Coway - AirMega 150 (AP-1019C)

I bought two air purifiers just last week after reading this sub! Coway 150 and ap-1512HH(W), they were on sale on Amazon.ca and I read somewhere I can use the carbon pellet filter from the AP-1512HHS in the non S version. So far so good!

Hey The Coway Airmega 150 is a solid unit, but it only has a CADR of 234 m³/h. For a 4.8 ACH, it's perfect for your room, but only if you run it at full speed. If you want to target a lower ACH, go for it, since most probably you won't run it on max speed. What I generally recommend is buying something way more powerful than what you need. Here's why: Purifiers with higher CADR than what you need mean you can run them on lower speeds to achieve the same CADR of a smaller one. This results in less noise, less mechanical stress on the purifier, and a longer life of the fans and longer filter lifespan. (The filter lifespan of ~1 year is calculated in a room suitable for the purifier. If you get a bigger purifier for a smaller room and run it on low speeds aka night mode or speed 1 instead of a normal usage you'll get more life out of the filter as well which translates to less frequent filter changes so $$ saved as well in the longer run) As per what I recommend, I would say go for at least a 350-400 m³/h CADR unit that provides a good noise level (look at both sleep mode and turbo noise) and power consumption. I am personally using a Philips PureProtect 3200 in my room (same room size as yours), but only because I caught it on sale for $206 usd. Since it has a whopping CADR of 520 m³/h my purifier is never leaving the sleep mode setting, and I can barely hear it. And for that CADR it is quieter on both sleep mode (15 dB vs 20 dB) and turbo ( 47.5 dB vs 48.3 dB) than an Airmega 150 while outputting 2.22x the performance of the Coway unit. Plus app support and temperature + humidity sensors if you like the extra stuff. This is the type of deal you want to be looking for. See what's up for sale in your country.

Coway is the best in industry. I can recommend Mi AP4 as well. It has everything that you need

I think people confuse between AQI and PM2.5. I have Mi AP4, and it shows PM2.5 reading instead of AQI. And I also have a AQI meter which shows both AQI and PM2.5. And Mi one shows the accurate 2.5 reading as the AQI meter. Honeywell is also good but I would rather go with either Coway for best purifier and Mi for best tech one.

Go with Coway if you have space. It is the best purifier. Otherwise Mi AP4 because of its compact size and tech features. And just go with AP4. The money you will save on lite is not worth it. I have the temtop P10 Air Quality meter but honestly, I got it because I was paranoid about the purifier working and wanted something to check it’s quality. But after the first week, I have rarely used it. Save your money, the purifiers work and you will know automatically if they are working or not. The AQI indicator on them are good enough.

So after spending more time looking into purifiers I went for something else. I bought a Coway Airmega 150 (for our attic bedroom) and a Coway Airmega 300s for downstairs. Both had 20% discount on their website and The 2 devices cost me less than the Daikin . Hopefully I made a good choice 😅

I ended up going with the Coway Airmega 150, and bought it on their website for a discount. Thanks!

I got the Coway 150 as well. What do you think of the Green HEPA?

Storm has a CADR of 360 and AM150 has 300. The price gap is huge. If your room is small to medium you should definitely go for the AM150.

I have a Coway 150, it works with a smart plug since it has power on memory.

I have 2 dyson hot+cool- cost /min is Rs.1 1 coway airmega 1019 - cost /min 50 paisa 1 coway 1018 - cost / min 50 paisa And Philips AC1215 (shittiest air purifier) - cost / min Rs.2

I use Coway from Amazon. So far I have the Airmega 100 for my bedroom and an Airmega 150 for the living area. Might get one more for my office at some point. ETA: I have severe allergies and migraines and I have noticed an improvement in both. I wake up with a clear nose and have had way fewer migraines.

I'd go for a Coway or a Winix. They both perform well cost/price-wise. Depending on the model, both brands have options with carbon filters (for bad smells). I own a Coway Airmega 150 and Winix Zero Pro. They've both been going strong without any issues for 4 years now.

I too am returning my coway 150 purely due to shitty auto mode which keeps on changing fan speeds like crazy. Moreover i believe they should have included more number of fan speeds. When the indicator shifts from green to yellow, the fan drastically becomes very fast which disturbs the person instantly. They should have gone with a smoother switch between green and yellow. You are absolutely correct the fan speed balance is damn. Fan speed 1 is very low and fan speed 2 is very loud.

I got the coway 150 2 days back but its auto mode isn't very peaceful, it keeps on fluctuating a lot compared to others, which disturbs a lot. Otherwise the cleaning efficiency is good. But due to auto mode i am returning it! For coway aim i can say is it doesn't resume on its own after a power cut which is a solid drawback. I haven't used it so can't comment on its auto mode I now will try the newly launched Honeywell v5

I ordered the coway 150. Thanks for your suggestions

Bro the coway 150 keeps switching from yellow to green every 2 minutes which is really annoying. This isn't the case with my other purifiers( philips, Havells). Atleast an air purifier should remain in the same level for atleast 5-10 minutes when all the doors are completely closed and there isn't any air entry from outside. The auto mode is very unstable. I have also checked with aqi meter, the speed keeps switching when the aqi is same!

No because of inconsistent auto mode

Auto mode is worst on coway 150, it keeps switching fan speeds instantly over and over which disturbs sleep a lot

I am using coway 150 from last week, no smell at all! Also coway aim doesn't resume by itself after a power cut but coway 150 does resume! But due to the auto mode fluctuations i am returning the coway and getting mi AP4

Ik heb ook een Coway. Airmega 150. Seems to work well.

I have the green 150 and just found another exact match at a garage sale so now my living room has two lol

Walmart had the Cowaway 150 at around $100, but as of yesterday morning they jumped back up to $170+. Not sure if it was the result of people seeing the great deal on various deal tracking sight, or if it was a jump in demand due to fires. The 150 has been in my room for 6 weeks and it has been great. There are some Coway models on Amazon, but you probably won't get them until Sunday/Monday. If you need something now, Costco carrys a Winix circular model that is in stock at the warehouse. The better Winix unit is only online from [Costco.com](http://Costco.com), so that won't likely arrive until next week. Best Buy will have units in stock.

Coway Airmega 150 or Airmega Aim. I have both and happy with both of them.

Similar to 150 if running full speed. The replacement filters are expensive in comparison but initial cost around 40% less.

I've been happy with my Coway 150, even if sometimes it gets noisy (vibrations).

Not just Air Purifier but please Vacuum Clean your home too. Dust and Pollen allergies with air pollution is given in Bangalore. Both of them together definitely helps. I use Coway Airmega 150 Professional Air Purifier and Karacher WD 3 Bag Vacuum cleaner.

Got mine from BlinkIt, had a last one left at the nearest store. 

Don't expect an aqi meter in a budget friendly air purifier. People expect way too much from air purifiers, a good aqi meter costs u about 5k and filters cost u 4k (company ko bhi profit kamana hai) coway ka color dikha deta hai to its enough and number dekhkar tum kya hee krloge I have a coway mega 150 and trust me there's no need of wifi(it's only useful when u come from office and u rlly need to switch it on before u enter ur house and that's it) U should go for coway Got it for 11250 during Diwali sale

Coway Airmega 150, was using one since 1 year, and ordered 2 more 5 minutes ago for other rooms.

That was yesterday. Just ordered 2 today from Amazon. See if its still there.

Oh ok, may have run out. I ordered mine in the morning.

My coway is stuck at red must be a filter/fan problem. Moral coway wil lsu k if your insulation is bad!

Coway 150 and Aim do make more noise than Mi air purifier. But yeah the expensive one of coway ie strom has 22-23 dB noise while Mi has 33 dB noise. But its winter and if i turn on my mi 4 lite during night in sleep mode, i can sleep peacefully. Both cover same area, coway storm is 2.5x times expensive than Mi 4 lite.

I just bought and loved it but then just found out I can’t pair it with n op and I am gutted!

I owned this C610 for 1 month and then returned it. It began making a non stop whining sound. Trash, bought a coway 150 instead and love it.

I had the exact same problem ! Returned it. Bought a coway instead.

For anyone still researching this purifier, I've checked my two units with an accurate PM2.5 monitor. On highest sensitivity, it actually tends to go blue (cleanest) after the PM2.5 drops under 8-10, which is actually pretty decent. Brought a smoky room of a 850 ft³ at PM2.5 200 under PM2.5 5 in 30 minutes with an 8 month old filter that just got flagged for a replacement by the machine. Going to compare it to my less used filter soon. My two units keep my apartment clean. With new filters, they could clean a 1700ft³ room in 20 minutes on max, and were able to keep the air clean (at PM2.5 of 1) on its medium setting. With both on max, they keep my 1400 sqft apartment under a PM2.5 of 3 with an outside level of 20

Ohh Thanks for sharing all this information mate I got my purifier yesterday, and I have to say, it MAKES a difference. I mean in the beginning I thought it was psychological as I have spent 14k that’s why I am feeling its difference😂 But no, Idk I can’t explain the difference properly but the main difference is that I feel room’s air lighter to breathe. It is like when I inhale outside the room, it feels like I filled my lungs as much as possible but still I am feeling some breathless and heaviness but inside the room I am feeling really airy and lighter. Idk if it’s still psychotic or not but thats my experience. Is it real or is it me only being delusional? Please tell

Also I want to know one thing from all coway airmega 150 buyers It has been 24 hours now, mine has started some mechanical ticking sound when the machine is in auto mode and light is green or blue. However it is a very light and little ticking that you can only hear if you place your ears near the fan. It comes only when fan runs at its lower and lowest levels, feels like something inside the fan setup is slamming. Is it normal in all (meaning the poor design problem or something) or should I just replace mine?

Coway is worth it. It is the topmost accurate models out there. It is the cheapest in terms of maintenance and filter changes.

Coway Airmega 150. Got it for 13K.

These are some good ones I could reccomend

They're all good. Coway is one of the better ones. Sharp has a really good product as well. I'd reccomend getting either of the two. Filters can range from anywhere between 2-4k for these devices, and you'll have to change them every year.

My location is around 150+ AQI, indoor with doors and windows closed. Have been running Coway Airmega 150 since last 3 hrs, still shows red. for some 10-20 seconds it shows light green but soon turned red. What's happening?🙄

Where do you find Coway airmega 150 filter at 1100 INR? I've just got one delivered and wanna return to buy an Mi or Honeywell just for the cost. Coway purifier is costly and even its filter is costlier than Mi. Coway doesn't even indicate AQI and the others show wrong AQI on display

I went by the same before buying But even after using Coway for 24 hrs during peak festivals it shows RED. in normal days it makes air to GREEN and during 10am to BLUE

Why rectangular? Have used air mega 150, it fails in a city like Delhi. one needs 2 of these in a 100sqft room in Delhi. Plus, air mega 150 is discontinued by Coway. Only benefit is washable Pre-Filter

Using Coway mega 150 plus Honrywell air V5 simultaneously in a 100 sqft closed room. Fail to go below 70 AQI from 10pm to 7am Delhi

don't like TWO working in 100sqft to do just that. Mi look more powerful ss heard. Sharp might be costly

I bought Mega 150 at 11k, was gwtting Aim at 7500 but cancelled it since Mega 150 has flat filter easily available

Coway is objectively better than Philips. [Philips AC0920](https://www.amazon.in/Philips-AC0920-Purifier-Allergens-Bedrooms/dp/B0DB83LFM3?linkCode=ll1&tag=trendtrond07-21&linkId=b31e9e3330c082f3981bbf15edfb74b3&language=en_IN&ref_=as_li_ss_tl&th=1) is suitable for mid-sized rooms (up to 380 sq ft). It has a 2-layer HEPA filtration mechanism. It is quiet, energy efficient and comes with a 2-year warranty. [Coway Airmega 150](https://www.amazon.in/Coway-Professional-Purifier-Anti-Virus-AP-1019C/dp/B08GJ57MKL?th=1&linkCode=ll1&tag=trendtrond07-21&linkId=870d38f08725eab610ad57d43863366d&language=en_IN&ref_=as_li_ss_tl) is also quiet and makes less noise (making it suitable for bedrooms). It also comes with a similar area coverage of around 355 sq ft. It is a best-selling device known for product quality. Also, the 7-year warranty makes it more attractive to buy. Go for Philips only if you want to cheap out in the short-term. Even taking the filter costs into account, Coway is cheap in the long run as the 7-year warranty will cover costs for the 7 year period. Coway is currently being sold at a discount and is even better to buy at the current price.

Using Coway Air Mega 150 from past 5 years. Works well!

I live in a peaceful residential area in Kolathur, Chennai, but there was major storm water drain work happening for months, and the dust inside our house became unbearable. My grandmother, who's over 80, started coughing and sneezing a lot, and her health was affected. At first, no one in the family believed an air purifier would help—my mom kept the windows shut and mopped daily, and my dad was skeptical too. But I decided to get one anyway. It's been six months now, and even though the construction is done, the dust that the purifier collects is shocking. The purifier has three filters: one for big dust particles, then a HEPA filter, and a carbon filter that tackles odors and gases. We run it 24/7, and we clean the dust filter every two weeks. The HEPA and carbon filters may need replacement after a year. It’s really made a difference, especially for my grandmother's health. So yes, I’d definitely recommend getting one. I have the Coway AirMega 150 model.

I have two of these as well. Have had them for several years. Easy to maintain. Plenty of third party filter options. First one is a bit older and you can’t turn off the lights. The second one you can turn them off. I assume it’s a standard feature now. Also run them 24/7 365.

Bought coway 2 weeks ago.... Go for it...

The one that looks box like. Yes but it has light indicator - like traffic signals. Red yellow green... Also I think you may want to check if Honeywell sells filters separately. Cz when I was researching availability of filter was also one parameter. Also coway was consistently on top 5 for all tech reviews for last 2 years, I did not check beyond that Took a leap of faith and have tested the machine a lot of home. Agarbatti bhi jaake ke dekha... Saamne jhadu bhi maarke dekha... It changed colors quite accurately to show if dust/ pollution has increased in the room. Please do this testing in a closed room. Khidki darwaze khol ke nahi. Dyson has been on top in case you have budget.

Correct!!

I finally took the plunge and got myself the Coway airmega 150. I was unable to find a lot of reviews here or on YouTube. So here's my mini review: Looks: Aesthetically, I love this thing. I opted for the blue version and it's so damn pretty (although my fiancee calls it a "large Lego brick lol) Noise: thing is dead silent on silent mode. If you put your ear next to it, all you can hear is some air moving. Setting 1 is audible. Setting 2 is too loud to use most of the time (but also moves a lot of air!). I heard some people complain about a whining noise or vibrations, but I have experienced no such thing. Performance: On "Silent" mode (settings are "silent, 1, 2" in my region, even though other variants use "1, 2, 3.") it moves some air, although not a lot (around 50 cubic meter an hour). Settings 1 and 2 are very efficient, but I rarely use setting 2 when I'm in the room due to noise. I haven't been able to test the carbon filter yet, but mine came with the apparently superiors carbon-pellet filter, as opposed to the carbon sheet. So I'm excited to see if it's able to remove some of the VOCs produced in our home (i.e. farts) "Smart" features: The Coway 150 has a PM sensor of sorts, but it's not very good. I set the sensitivity to its highest setting just to see what would happen and the machine would constantly rev up and down, going from silent to 1 and 2 several times in the span of a few minutes. So I put it back to normal sensitivity. I don't think normal sensitivity is sensitive enough, however. I would recommend to manually adjust the settings to your needs. In hindsight, I should probably have gone with the Coway 250 to be able to move more air more quietly. Our living room is around 213 square feet, which is almost too large for the 150. But I opted for the 150 because of its 20db silent mode to be used in the bedroom at night. All in all, I'm quite happy with my purchase and would recommend it for smaller spaces where noise is a concern.

I’ve Coway airmega 150 and noticed a clear improvement in my symptoms once I got it

AirMega Aim is a great product for a specific situation. If you got allergies and you just want a fan, that blows clean air at your face, then go for it. It is not mainly meant to clean the air in your room, but it will do that a little bit. Airmega 150 if you’re looking for quality, it will be worth it.

I was going to go for the coway mighty, but ended up choosing the 150 purely because it has activated carbon filters, while being cheaper than the mighty filters.

where did you hear that its discontinued? Infact, its one of the models that got slight revision, changed the slim poopy charcoal filters to proper activated ones..

Mi tends to have a faulty air sensor. I had to return mine twice. Coway is goated. Go for it.

I don't like the fabric design either. I just got a 211, because I need to clean a bigger room and it was the only good deal on craigslist. I can't imagine it being graceful to remove without making a dust cloud. I've also seen some comments that cats can interpret it as a scratching post... I've always had brand loyalty to coway (they lowered the cost of home air purifiers, right when I needed it); the cover keeps the dust contained, and their stack set-up of a prefilter, charcoal, then hepa makes clean-up much easier. I don't think I even need to take it outside. Winix has the same setup. I have one newer coway 150; these are more modern, and I don't like the sliding prefilter -- if you make the mistake of not letting it coast down and it's dirty, the air blows the dust around. Yuck.

I would avoid Dyson purifiers. Their Clean Air Delivery Rates (CADRs) are too low. The standard rule is that CADRs should be *at minimum* 2/3 of your room's area (assuming at 8 feet or 2.4 meters high ceiling). With a baby and high pollution levels, it would be wise to increase CADRs well beyond this rule. The next issue is sound levels. According to a *Pediatrics* article, the "recommended noise limit for infants in \[USA\] hospital nurseries" is 50 dBA (decibels A-weighted).^(1) Many air purifiers exceed this threshold on their higher or highest speed settings. To compound the problem, many sound level specifications do not match real world sound output. Purifiers are often louder in your home than what the brand states. Air purifier CADRs are greatly reduced on the quieter lower settings. This would be inadequate for a high pollution environment. Therefore I would recommend buying *multiple* air purifiers and running them at a middle speed setting. Using a [sound level meter](https://en.wikipedia.org/wiki/Sound_level_meter) would give you an exact measurement as to actual decibel levels for each speed. My first recommendation in terms of brands would be **Coway**. They offer higher quality than Philips, Dyson, or Levoit and ensure availability of filters for discontinued models (from what I've heard online). Models could be: * [Coway AirMega 150](https://cowayindia.in/coway-airmega-150) air purifiers: ₹13,900 each \[purchase 3 units\] * [Coway AirMega Storm](https://cowayindia.in/coway-airmega-storm) air purifiers: ₹24,900 each \[purchase 2 units\] You may need to ask Coway about CADRs for each speed setting on the purifier you want to purchase. I'm American, so unfortunately I have no familiarity with vendors or retailers of Coway purifiers in India. The Coway AirMega Storm may be out of stock or no longer on sale. Other considerations: * [Philips Smart Air Purifier (AC4221/61)](https://www.domesticappliances.philips.co.in/air-purifier/ac4221-61): ₹23,399 each on [Amazon India](https://www.amazon.in/Philips-AC4221-Purifier-Display-Allergen/dp/B0DB83DSSJ/) \[purchase 2 units\]. Someone claimed in this subreddit that Philips may not ensure filter availability for discontinued purifier models. For the [Levoit Core 300S](https://www.amazon.in/Purifier-Particles-Warranty-Indicator-compatible/dp/B08L73QL1V), I would purchase *three* of these units due to the lower CADR (240 m³/h). ---------------------------------------------------------------------------------- ^(1)Article cited is Hugh et al., "Infant Sleep Machines and Hazardous Sound Pressure Levels" in *Pediatrics*, (April 2014), Permalink: [https://doi.org/10.1542/peds.2013-3617](https://doi.org/10.1542/peds.2013-3617)

Yes, I like the **Coway Airmega 150** for smaller rooms. I'd say the maximum room size for this model would be 229 sq. ft. with an 8 ft. ceiling, calculated by the Smoke CADR of 153 CFM. The **Coway Airmega 200M** is a good performer for that price. Maximum room size should be 369 sq. ft. with an 8 ft. ceiling based on a Smoke CADR of 246 CFM. However, it appears to be louder at its top speed (55.1 dBA or decibels A-weighted). The **Airmega 200M** also has an ionizer which can be switched on or off. If you have any pet birds, you'll want to keep the ionizer off. This is due to the possibility of a small amount of ozone generation; birds are much more sensitive than humans. Keeping the ionizer off may affect the CADR somewhat, although I don't know by how much. A few studies are concerned ion generation can react to produce byproduct pollutants (typically gases) in the air.

Recently got 3 Coway 150 and 1 Winix 5300-2. Im really liking the Coway 150, but Winix is good as well.

Coway 150 is in my current room and winix is in other room so I cant say too much. But Coway seems quieter and seem to blow stronger air at max settings. Coway has 3 levels and Winix has 4. But If i were to get more purifier, I'd lean towards Coway. With that said, I believe replacement filter for Winix is more affordable compared to coway. (coway also looks better if you care about the design)

i have the coway airmega 150. did me good all last quarter

I have this one in my son's room and I'm happy too. I also have the 250, 300 and 400. I'm very satisfied with Conway. 

I got the model delivered today. Looks - on the internet, it looked like a boring ,inspired kind of design. In real life, it looks good - minimalistic and well proportionate. Performance - I don't have a professional aqi meter so don't actually know the efficacy. But it seems like it works. No funky smell which I have experienced in other air purifiers! Also, when I move out of the room, the air feels smoky. Switched it on and it showed red. (My city's aqi is 400+) I put it on the highest mode for 20 minutes and it got to green (2nd best aqi). Within the next 10 minutes it became blue(best aqi). Then I put it on fan 1 - the noise is like a split AC -very much tolerable. The air quality shifts between green and blue. Works alright in this room. This room has no visible gaps anywhere. Scenario 2 - in one room the purifier couldn't achieve the green level even after 30 minutes. The reason probably - because that room has glass partion on one side with a glass door which has some minute gaps. I tested the Philips air purifier and that also didn't change from red indicator in that room. Auto mode- it doesn't have much utility since the air quality keeps on changing and so the fan speed also keeps on changing. Once the purifier shows blue level, it goes into silent mode which is inadequate for high aqi. Then the air purifier shows green ,and the fan speeds up. Conclusion - I feel the auto mode is useless like in the other air purifiers. But overall the purifier is good. Use it on the highest setting for initial 30-40 minutes till it stablises on blue and then put it on mode 1 (low noise) - it will keep the air quality satisfactory- usually at blue (sometimes shifting to green) if you don't keep openning the doors now and then. Price - got it for 13 thousand rupees which is a little costlier - a month back it was available for 10,500 rs on amazon. Also, it doesn't have any other feature like timer or app connection.but had to buy it now since the aqi levels are booming. Alternatives - I did not want a circular filter type purifier. They don't have a washable prefilter mesh. But companies like sharp and Honeywell are similarly priced. I couldn't find much testing reviews of those companies so went with coway. Cons 1. The fan speed levels are not balanced.speed 1 is low but the aqi jumps up. While the only other option speed 2 is too noisy. Should have provided more fan speeds But in conclusion,I feel like coway is much better than Philips AC 1215

Got a new coway 150 yesterday. Never touched green even after 6 hrs of running on day 1. Its the market leader, don't expect much from newbies like Qubo on this tough wicket.

i have the coway 150, happy with it,simple straightforward and does a good job

The aim is inferior to the 150 in every way. It is not the same at all.

You have a cat - be aware, hair will get in the unit. DO NOT buy a cheap round purifier. They will get fouled very quickly. Levoit VITAL (not Core) is a good choice. As is Winix 5500-2, Coway Mighty or 150. 3 rooms at 300 square feet each shouldn't be an issue, but you may want to size up for the largest space (living room, I'd assume) which could certainly use a Coway 250 instead. If it were me, I'd do Coway 150 or Winix 5500 or Levoit Vital in the bedrooms, and Coway 250 in the living space, unless your master bedroom is bigger. In our house we have Coway 250 in the Master, smaller units in the other bedrooms, and another larger unit in the living area.

The Winix 5500-2 is better than the C545, and roughly equivalent to the Coway 150. The 150 is newer design and likely quieter. :) Those are the two I'd be looking at.

Mi 4 lite uses hepa 12 which is not that effective against delhi pollution, you need "true hepa" or "hepa 13" for proper filtration. I suggest you go for airmega 150 as it has hepa 13 and one of the lowest filter replacement costs in the hepa 13 segment. Plus the airmega 150 is really practically designed. No bullshit aqi meter or app features, just turn it on and it easily clears a room of 350 sqft in like half an hour. Everyone should consider filter replacement costs.

We have a Coway Airmega in the nursery and absolutely love it. BUT I will say there is a super cheap alternative that is just as good. Buy a 20 inch box fan and a 20 x 20 HEPA air filter. Tape it on the back and it works perfectly! It's just louder. But highly effective, we have multiple of these around the house!

The only smaller air purifier I have is the $200 Conway in my kitchen. Its like a jet engine when on high speed. That's OK when I've burnt something. But there is no way people are running it at that noise level in general use. The smaller the air purifier the more likely that its homeopathic in real use. Also, with a home's ducted HVAC system running, the air cleaner is attempting to clean the whole house.

We’re super happy with the Coway ones we got! We’ve got both of the midrange models. They were on sale yesterday.

They are minimalist and we have one in the bedroom! It has a smaller footprint than the comparable Levoit and it’s easier to carry around. It’s not small per se, but for what it is I find it very unobtrusive. Huge fan honestly.

Coway and BlueAir are great. Make sure it says "True HEPA," unless you build a corsi-rosenthal box Levoit ones aren't always true hepa.

I have two Coway Airmegas and a Winix D4. I prefer the Coway. They all make a significant difference with the smoke.

I have a Conway Airmega for my chicken brooder (chickens create a ton of dust as they grow, and they have to be inside for a few weeks cause they don’t have feathers yet) and it really cuts down on the dust.

I have 1 Conway AirMega ($170 ea) in each room that runs on med 24/7 365. Prior to the air purifiers the kids n wife would always have allergies n congestion/cough for what seemed like year round. My wife would have to pop Benadryl till it knocked her out. Slowly I started putting the air purifiers in each room, vacuuming the pre filter every time we vacuum the floors and they’ve gotten so much better since then. It’s been several years at this point. They still have the allergy fits every once n a while but it’s a lot less frequent. It’s not the prettiest solution to have one in every room, but for us I think it’s been worth the ongoing expense as the filters aren’t particularly cheap ($34 for 2). I’ve done a few other things that probably helped too. I swapped out the 1 inch filter return registers for 4 inch returns. I get 4 inch merv 13s from AprilAire. And I also started vacuuming with a true hepa vacuum.

Used these for 3-4 years. Never broke. They do the job but a Conway airmega is significantly quieter and an handle a bigger space, also has air quality monitoring that is super helpful and can be set to automatically increase filtration if air quality is poor. That said Levoit remains an excellent choice if you’re on more of a budget.

I love my Coway AirMega! We’ve had it for a few years now and any time we have strong cooking smells or if I spray some hairspray, it kicks into gear and I can tell it’s working! Can’t speak to the longevity/BIFL just yet but I’ve been happy thus far and it seems like it’s great quality. I also buy their name brand filters. *EDIT: brand is “Coway” and phone auto corrected to “Conway”

Yep, we’re a 4 Coway household here too.

I’ve had Coway AirMegas, Winix, and Whirlpool Whispure, and Coway is by far the best home purifier in my opinion. I have an AirThings air quality monitor and a dust allergy, and these filters make a difference. You do need to clean the Coway prefilter regularly, but it’s easy to do. I didn’t know they sold off market filters so I’ll have to look into that because the filters can be costly.

I have 2 Coway airmegas that are super quiet that I’ve had for nearly 2 years. Do you change your filters regularly? Only one I would not recommend is Winix—I had one of the smaller models and its noise was very inconsistent and it was poorly constructed compared to the Coway Airmega and the Honeywell Whispure (a tiny model).

I have 3-4 Coway Airmegas and Winix 5500s. I found them all on my local Facebook Marketplace for $50-75 over the last 12 months. All in great condition. Previous owners sold because they were moving (college students; young professionals).

Buy the Coway air mega it usually goes on sale pretty often. 10/10

If I’d known about Austin Air when I bought my Coway Air Mega and Blue Air, I would’ve definitely picked Austin Air and I may still get one. It’s pricey, but so are Coway and Blue Air when you add up the cumulative price of filters. And, I find I need filter replacements much more often than recommended further increasing the cost.

Coway airmega it's excellent. I have mine going 24 hours a day and it senses everything. It also filters the tiniest particles.

The airmega. You can buy filters specifically for dust. There's 3 different types of filters i believe you can buy, the original and two more alternatives

This is the choice - had mine over a year and still going strong

We have two Coway Airmega units, one on either side of the house. They have been on 24/7 for several years now. Maintenance and cleaning are very minimal. Cost is about $150-200, although there are larger units based on how big of an area you need to filter. We are very happy with them! Whichever purifier you choose, I highly recommend you look into one with a replaceable HEPA filter. Other filtration methods just won’t give the same results.

Agreed! And they now offer different filters depending on what is most important to you to filter: one for smoke, one for allergens, etc.

This is the only correct answer. Don’t get air mega aim tho that’s a scam

Seconding. Got ours 2020 so can't really vouch for the longevity. We usually keep it on auto... though once in awhile we have to go turn it off when watching TV because it goes into overdrive for no apparent reason-- but this is fairly rare.

We have a 2500 sq ft home so we have several air purifiers. I went off wirecutter’s list and got Coway Airmega for the rooms with higher ceilings and Levoit for the kid rooms and office (where the litter box is). We have had them for a year and I’m happy with them. They’ve significantly cut down on daycare illness transmission within our household. Instead of all 4 of us getting sick it’s 1 kid and sometimes 1 parent per illness.

I have one. They are legit.

We also have the Coway Airmega. Have one on each floor. They work very well. However, we prefer the replacement filters no direct from Coway- read the reviews on Amazon, but the Coway ones had some issues with plastic smells/making air quality worse. Some type of defect.

Coway airmega gets my vote. Got 2 on amazon since pademic and they've been pretty good by far.

I have the Coway mega and a taotronics ap-003. I like the taotronics ap-003 more and it cost 85 usd.

I've got a Coway airmega in our bedroom, and a BlueAir in my office at work. I love both of them... I'm a therapist and work in an 8'x10' room talking to people for an hour 5-6 hours some days. I think the BlueAir is a big reason why I haven't picked up any of the respiratory stuff some clients have come in with (well, that + vaccines + mindful hand washing/sanitizing). It's also pretty quiet which is important to me. I'm planning on picking up another BlueAir or two for the rest of my house this spring. The pricepoint is kinder than my Coway, and it's much quieter.

Coway Airmega; which model depends on the size of the space. Make sure it has a charcoal filter.

This. I have a winix 5500, two blue air 411s and two coway airmegas and the coway is my favorite by far.

\+1 Coway Airmega.

I picked up a coway airmega during the Smokey season last year and let it run in the living room. It does a pretty good job of keeping the dust, cooking odor and old house smell to a minimum.

The sensors are amazing. The review on Amazon sold me " my dog farted and it instantly kicked on and I never smell them anymore" Yes whenever I cook or smoke they instantly kick on and work really well.

I really like the Levoit. It’s super quiet on the lowest setting and you can turn the lights off. My husband is a bozo who needs white noise to sleep so he always turns it up to its highest setting and then doesn’t turn the lights off. We have a coway airmega for our living area but I prefer the way the Levoit looks and my older son kept messing with the coway and it got stuck on a setting so I can’t turn it up or down. ETA I also have a roomba because I am allergic to dogs but my dog is my favorite child and I let him sleep on my bed during the day.

Air purifiers aren’t regulated so getting one that has undergone 3rd party testing is important in order to know they do what they claim they do. Coway Airmega does 3rd party testing. The ones that have an ozone setting have it as optional — something you have to turn on to use. We just never use it. Insane to me that they even have those. Yes, ozone is bad for people with asthma. Also bad for pets, especially birds. And probably people generally. I love that my coways automatically rev up in response to detected poor air quality. And they are whisper quiet when just in background mode. We only notice them when the go into high gear — usually when we are cooking. Edit to add: wirecutter still rates coway as a top purifier: https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

I’ve had mine for over 6 years and they’re still going strong. I love them

Coway Airmega looks like a solid pick, especially as it’s clearing out musty smells and reducing allergens while adding that cool breeze feature. I’ve run a few models non-stop in rooms with high humidity, and once they started picking up those subtle odors, I knew I was onto something. I’ve tried some models from Blueair and Medify before, but ConsumerRating is what I ended up trusting because it lined up features like filter life and energy efficiency to my needs. Coway seems to hit that balance of performance and reliability, which is exactly what I’m after.

I have three too. They've run 24/7 for years without an issue. Third party filters work fine and are half the price.

I recommend the Coway Airmegas. To be effective, it will need to run at full blast. Get one with a high CADR or pick up multiples.

I vote for Coway Airmega. I have 3 of them and they’re great

We bought an Airmega four years ago (the last big wildfire year in California's bay area) and it's been a terrific purchase. It helped then with that acute problem, but it also helps keep particulates low year round. It's quiet, doesn't take a huge amount of space, and it makes a noticeable difference in the main living areas of our home (I don't expect it to work in bedrooms at the other end of the house). Do recommend, but the Coway app is pretty crappy.

I don't think those will be effective in such a large open space. For heating and cooling, with what you could spend on a couple of those Dysons, you could get a mini-split heat pump for heating and cooling. As a purifier the BP04 will be okay but you can spend half as much for better performance with a Coway Airmega or Nuwave Oxypure. You could build a Corsi-Rosenthal box for the best performance to price, but DIY isn't for everyone.

I have 4 Coway AirMegas in my house they’re great

That’s what we have! My baby is also obsessed with it; not a day goes by that he doesn’t crawl up to it and start poking his little fingers into the holes on the front 😂

I love my coway airmega.

I have several Coway airmega and they are legit wonderful. They have an app so I can set programs for the speed, and report on air quality. I run these full time for years and they still are working great. Ive had several other brands but these are the best.

I tried a Dyson TP07 once, but it felt pricey for my budget, so I leaned toward Coway Airmega because it handles pet hair and dust pretty nicely.

I have a Coway Airmega at home, and it handles smoke and pet dander well without getting too loud.

I have two Coway Airmega that run like absolute champs and have very widely available and affordable filters

We're so happy with our 2 Coway Airmega for each bedroom.

Me too! I’ve tried the fancier copay’s but this one is the best for the money. Filters are reasonable and it has good power to circulate air. 

I love the Coway Airmega! I run it all day in the living room. Thinking about a small one fit the bedroom too.

First thing I want to say and it's important. The most important thing you need to know is that the air purifier has got to have true HEPA that is not an option ... 3m/filtrete is a joke of a purifier. They are terrible and do not last. biggest problem you have with their air purifiers are they are not sealed purifiers. There is a lot of dust that gets through other places and bypasses the filter in the unit and then what happens is it collects after the output vent so you will eventually start seeing dust there. Another is their filter cost. It's insane. if you look at their filter replacement schedule, it says the filter lasts 12 months used six hours a day.... air purifier are supposed to run 24/7 to have full effect so if you run it 24 seven that’s every three months their filters are also small... but I personally recommend and have used the past is these two for your size room are these I'll link. you get an air purifier that is going to be more powerful in your price range and will last for starters... There’s a reason why you want something with a higher CADR is because it will clean the air more frequently in that room and clean it better. You will get more air changes per hour basically and that’s a good thing. Also, you’re not gonna have dust getting past your filters and leaking out of the top of collecting everywhere else. You will also get a true 12 month filter when you run it 24/7. It comes with a TRUE HEPA and four replacement carbon filters. One of them will even include a additional year of filters if not both of them out of the box. The Coway Airmega is also another amazing air purifier for the price, however the filter costs have you replacing filters every 3 or 4 months with full use. Alen is also expensive from the get go but filters are annual. I have used these Winx purifiers in the past and I love them the plasmawave can be turned on or off I'd it's a concern but it doesn't produce ozone. I am just linking site so you can get all the information on them however I don’t know if you have a Costco membership or they still sell them or not but it was a great place to get these at an even cheaper price. https://www.winixamerica.com/product/c535/?_gl=1*1v4e0th*_up*MQ..&gclid=CjwKCAjwwLO_BhB2EiwAx2e-35mFNXJgc1BeCOGMGegBQ-An_KwmCD6L29mTNy-0yyIBkVrET2C_jhoC034QAvD_BwE https://www.winixamerica.com/product/c545/?_gl=1*u8q5cp*_up*MQ..&gclid=CjwKCAjwwLO_BhB2EiwAx2e-35mFNXJgc1BeCOGMGegBQ-An_KwmCD6L29mTNy-0yyIBkVrET2C_jhoC034QAvD_BwE

Coways are sold in europe but you need to find them on sale and that only happens once in a while, I was able to get my coway airmega for \~450 eur. Your other options are AEG (currently having lots of discounts) and winix. There is also rowenta, phillips & amazon basic, I personally don't like rowenta so I'd avoid it. If I was looking for a purifier, I'd try to get the AX9, has an insane CADR and costs around 330 eur right now.

I followed the Wirecutter recommendation and have a Coway Airmega. Two technically, one for our room and one for the baby's room. My allergies are a lot better after using them. My only gripe is that the first one we got makes a slight knocking noise sometimes, like it's just a bit out of balance. Usually if I turn it off, let it sit for a minute, and turn it back on again it goes away, but it absolutely drove me nuts when I was trying to sleep. I can't hear it over the white noise machine we use now though.

We've been happy with Coway airmega (one for kitchen, one for bedroom).

Wirecutter recommended the Coway Airmega. I got 2, one for the living room and one for the main bedroom. They have a sensor and cycle higher when there’s more particulates in the air. It has a prefilled and a main filter (that you change only once a year). It has an indicator light to tell you when to clean/change. Here’s the wirecutter piece: https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

These. I raise pet pigeons (very very dusty) in my house and these are what I use.

so you need specifically, a HEPA filter - Austin Air makes a terrific one. So does Coway - the AirMega

For what its worth, NY Times Wirecutter blog tested a bunch and ranked the Coway Air Mega as the best option. I bought one and am happy with it. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

budget budget, build a corsi-rosenthal  otherwise, get a coway airmega. it's a little pricier than some but it has a carbon filter which is great for smells. prefilter catches a lot and saves wear and tear on the hepa panel

The Coway Airmega is really good. We have three of the larger model.

Is there enough ventilation overall? Opening windows in the winter will dry out the interior air but a fan or air purifier is just recirculating the air already in the room. I recently got an Inkbird CO2 sensor to see when it's getting stuffy. I did a DIY hack turning a 自然換気口 (passive air inlet vent) into a powered intake fan that has a PM filter. The models were basically the same size so it was an easy swap. Then I ran an extension cable to an outlet. For air purifiers I use Airmega Coway as the filters are robust. I don't use humidifiers due to condensation risk from poor construction (less of an issue in concrete mansion).

I've had a Coway airmega going 24/7 for six years that hasn't developed any noise problems

Second the coway airmega- we use it for our kid's room, but have it on a set setting (rather than the auto setting) because when it would turn on to max air purifier it gets pretty loud.

After pursuing BIFL I decided to pick one up as well. I have two kids with seasonal allergies and this thing has been amazing!!!

Second Coway.

Agree. Our Coway Airmega does a great job, and has an "economy auto" mode you can just leave it on all the time. And if you remove and brush pet hair off the prefilter once in a while, your filters should last a long time.

The Coway Mega is fantastic for dust, pet dander, woodsmoke. Had mine for a year now.

Coway Air Mega for the win! It’s big. It’s quiet on low speed. Did I say it’s big? It sucks a vacuum cleaners worth of crap out of my air every three or four months.

This one is kinda meh. Get a Coway Airmega instead

We have a Levoit Everest-air by our grey’s cage, and a couple of Coway Airmegas in each bedroom. I would say an air purifier is mandatory for your health if you own a dusty bird like a grey. Always turn off the ionizer (or get one without it A prefilter that is removable for cleaning is super handy. If you keep it washed (or vacuumed) your air filter lasts so much longer. It’s crazy the amount of dust that collects on the prefilters!

I’m a huge anti-viral illness and clean air mindful person and based on my research and cost, I’d recommend the Coway Airmega. The prices can be decent, sleek look, not too loud, and most importantly they have many articles out there recommending them for actually working.

I’m in the uk and got a Coway airmega and it’s great. Did my research and wouldn’t change it. If you reaaaaaaly want to go all in, there’s some guys on yt that build their own using PC fans but it’s a bit overkill

Coway room aipurifier is amazing. We have it in our bedroom. Though our area is quite clean it does remove dust and fungal odour during winters
