Coway - Airmega 240

Noise is an important aspect to consider. A noisy filter will likely never be on. It's not just about sound level. It's about how annoying/soothing the sound your filter produces is. On this aspect I l like Coway's airmega 150 and 240. It's also easy to find replacement filters for these models.

Get the Coway Airmega 240. Its on sale and should be around the 1512 price and it's more powerful. You want to oversize it so you don't have to run at max speed. If you got the space and money the Airmega 300 is a nice unit also. Blue air is garbage!

If i were re-buying for a large space, id consoder trying to get my hands on the airmega 240 but it seems to be out of stock https://cowaymega.com/products/airmega-240 Or the airmega250 https://cowaymega.com/products/airmega-250?srsltid=AfmBOopMFwg2kp4uHXLg6CFV-JDBNwspkjiAVJNPEuy2c7nXEakKbirz which is also often sold out apparently. we have an airmega 150 in each bed room and they are awesome https://nl.coway.com/products/airmega-151?srsltid=AfmBOoo63FcMmUk2KnsIu0J6h55Q6nfrxzyrCVz05W6ltykwF44dmMC3q We have the airmega mighty in our large living dining kitchen area https://nl.coway.com/products/airmega-mighty-1?variant=39686230671432 it works well but is uglier than the 240 and 250 that are currently sold out. You can find more information on this sub https://www.reddit.com/r/AirPurifiers/ including threads that will explain what you can and cannot expect from an air filter (not do much heavy dust removal unless you buy units much much larger than the minimum, how to calculate the needed air turnover rate for your case and space, etc...)

Do have the Coway 250 as an option? I got one for $250 open box or refurbished on Amazon. It’s amazing. The sound it makes is very pleasant and it’s easy to clean, and aesthetic. The Coway or 240 is also a good choice and comes in white. The Winix 5500-2 or C535/C545 is also a solid choice and a bit more affordable. I believe Costco has good deals on the C545. Lastly, you could check local marketplaces. I got some Winix, and Blue Air purifiers (the 203 slim, 403, and 503) for a great price.

I just did this a couple of years ago. I put an air purifier in every bedroom, the office and living room in my home. I went with coway. I got a combo of 240s and 400s

Yes, they’ve been great. Would purchase again

Grab one that's bigger than you need so you can run it on level 2 and it wont be so loud, and more efficient. If you want one without ozone, get one that does not have a UV or ionizer. Coway240 would be good for you. I bought one for my room, have been running for a week. so far so good.

right. grab a couple coway 240's and call it a day.

Hey! i recently spent the better half of a week scouring the interent for what i beelived to be a really quality air purifier but at a cost effective price. It really deepnds on your budget. I would say around $600 i would suggest the better Coway models or the air oasis personal. for around $1000 id suggest the austinn air units with all that activated charcoal or some higher end from IQ air. Above that i beleive youd be better to have medical grade purification system installed with your HVAC system, for several grand. I trecently bought a cheaper aproxx $300 unit, the \*coway 240\* , and think its the absolute best air purifier for under $400, however the coway 400 is astep up( and probably worth the extra hundreds if youre purifying a large living quarters. It can often be found at a discounted price(under around 400, a good deal) ive heard. I went with coway240 for size and im only purifying my bedroom. i wouldnt go ANY cheaper than the coway 400 or 240 models and think they are the most cost effective but very reliably proven purifiers. IF you MUST go lower id look into wynix.... thats it. anyways, I have no complaints about the coway 240 and i have notice iit battle a little smell(remember you need a decent amount of charcoal to absorb substantial amount of smell, if youre really looking for smell reduction the autin air unit are probably best, tons of activated charcoal) Im completely new to air purifier too! but there thats my novice two cents, also i DEFINITELY suggest consulting the "buying guide" here in this reddit, very useful.

Okay, so minimum CADRs of 240 CFM. We usually recommend the Coway brand first as they offer higher quality units. For the 30' x 12' space, the [Coway Airmega 240 in Warm Gray](https://cowaymega.com/products/airmega-240?variant=42429066248446) would be good. It's also available on sale in [Dove White at Sylvane for $239.99](https://www.sylvane.com/coway-airmega-240-hepa-air-purifier.html).

he Coway models you listed would be underpowered for the \~500 sq. ft. space; you'd need \~334 CFM CADRs. CADRs should be *at minimum* 2/3 of a room's area (assuming an 8 ft. ceiling). I would avoid the Coway Airmega 100 in particular. Coway is better quality than almost all other consumer brands on the market, but they're more expensive. Some of their Smoke CADRs are low even on the more expensive models. So you'd need two air purifiers to meet CADRs in that room (e.g., one [Coway Airmega 240](https://cowaymega.ca/products/airmega-240?variant=40263676592170) and a [Coway Airmega 160](https://cowaymega.ca/products/airmega-160)). The only purifier that comes close to all except one particulate CADR and budget is the Winix C909. Drawbacks: it's loud on "Turbo"; using the Decibel X app, my C909 measured 60 dBA. Winix is more mid-grade with some people reporting whirring, whining, or clicking noises after the 2 year mark. This is usually a motor bearings issue. PlasmaWave (the ionizer) generally aids the Pollen CADR. It's possible you could see a drop in this value if it's turned off. Keep in mind CADRs are for the highest speed setting only. Lower speeds have lower CADRs. **Winix C909** * Dust CADR: 336 CFM * Pollen CADR: 384 CFM * Smoke CADR: 323 CFM * Price: [$289.99 CAD at Costco.com only](https://www.costco.ca/winix-c909-4-stage-air-purifier-with-wifi-and-plasmawave-technology.product.4000257649.html) EDITED: I glossed over your post and didn't see the "Canada" bit. I've corrected links to their Canadian countertparts.

Per [AHAM](https://ahamverifide.org/ahams-air-filtration-standards/), the particulate Smoke Clean Air Delivery Rate (CADR) should equal your room's area (assuming an 8 ft. ceiling) for wildfire smoke treatment. I assume the small apartment is mostly open plan? Purifiers can't overcome walls and doors. * Big bedroom: minimum Smoke CADR of 155 CFM * Small apartment: min. Smoke CADR of 240 CFM The Honeywell purifier you linked has a Smoke CADR of 110 CFM, so it's underpowered for both rooms. You haven't listed a budget, so my suggestions might not be suitable. The big bedroom and small apartment could each have their own [**Coway Airmega 240**](https://cowaymega.ca/products/airmega-240). Its top Smoke CADR is 282 CFM. Coway is a high quality consumer-grade brand. If you want to order directly from Coway, use the code **COWAYMEGA10** for an extra 10% off. Alternatively, each space could have its own [**Levoit Vital 200S**](https://www.amazon.ca/Purifiers-Bedroom-Powerfully-Allergies-Coverage/dp/B0BGPF71Q6/?th=1). Its top Smoke CADR is 250 CFM. Levoit is lower quality than Coway and more of a mid-grade brand. Keep in mind that the CADRs listed are for the highest airflow speed/setting only. Lower settings have lower CADRs, which means reduced cleaning effectiveness.

Not sure where you're seeing the [Coway Airmega 400](https://cowaymega.com/products/airmega-400) CADRs, but I included the Coway product page link in my last comment and now this one. As taken from that page, CADRs are: * Dust: 328 CFM * Pollen: 400 CFM * Smoke: 328 CFM The [Airmega AP-1512HH Mighty](https://cowaymega.com/products/mighty-ap-1512hh) uses the "Vital Ionizer", a bipolar ion generator. Turning it off may affect one or more particulate type CADRs. And if the highest setting is too loud, you'd have to use a lower one... the second highest one would probably give you adequate CADRs. If you didn't want to spend that much on the Airmega 400, you could also consider the [Coway Airmega 240](https://cowaymega.com/products/airmega-240) for your bedroom \[240 is sold out at Coway currently, but still [available from Sylvane.com](https://www.sylvane.com/products/coway-airmega-240-hepa-air-purifier)\*\]. There's a discount code at the moment for Sylvane that gives random discounts - **SPOOKY**. As for third party filters, it's a gamble in terms of like-for-like performance. They may void your warranty. I don't know anything about Cabiclean filters.

Generally you have to spend more for higher CADRs, better energy efficiency, good reliability/build quality, and quiet(er) operation. I don't know how much noise you can tolerate while sleeping. Coway is a high quality consumer-grade brand. If it's in your budget, I would consider the [**Coway Airmega 240**](https://cowaymega.com/products/airmega-240). Keep in mind that the CADRs listed for purifiers apply to the highest airflow speed/setting *only*. Lower settings have lower CADRs, which reduces cleaning effectiveness. If you want to directly order from Coway, use the discount codes **COWAYMEGA10** or **FORYOU10** for 10% off.

Yes, in my opinion. The Airmega 240 has higher CADRs, is more energy efficient, and has activated carbon pellets\* unlike the Airmega AP-1512HH Mighty. \*To be fair, Coway and most other common air purifier brands have very little activated carbon for gases, vapors, or odors. Coway et al. are designed for particulates capture instead.

Quite a lot, unless you want to use a less restrictive filter. Smoke CADRs tend to be a bit lower than Dust or Pollen CADRs (not always). The cheaper compromise is the [AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro), a Corsi-Rosenthal box design using proprietary Efficient Particulate Air (EPA) E11 filters. E11 is two filter classes below H13 in the [EN 1822-1:2019](https://www.airum.com/frontend/immagini/files/EN%201822-1.PDF) standard. No Smoke CADR exists because the AirFanta is not tested to ANSI/AHAM AC-1-2020. Instead, it's tested to the GB/T 18801-2015 Air Cleaner" standard which yields a top composite CADR of 413 CFM. There is an option for E11 filters containing activated carbon. It won't be terribly quiet on high though. You'd need two units, especially if you run them on lower settings for quieter performance. It's $176 with the combined E11 + activated carbon filters. If you wanted a traditional air purifier using H13 HEPA, you could go with two [Coway Airmega 240](https://cowaymega.com/products/airmega-240?variant=42429066215678) purifiers. Smoke CADR for one unit is 282 CFM. Coway is considered one of the highest quality consumer brands.

Yes, although the best time to have purchased a purifier was likely during the Amazon Prime Days when I made my initial comment (July 9th). Other websites discounted their goods heavily to compete with Amazon. You could buy *two* [Coway Airmega 240](https://cowaymega.com/products/airmega-240) purifiers. Two of these have a combined top Smoke CADR of 564 CFM | top Dust CADR of 584 CFM | top Pollen CADR of 686 CFM. If you want to buy directly from Coway, use the discount code **COWAYMEGA10** or **FORYOU10** for 10% off.

I noticed you said your ceiling measurements aren't actually 12 ft. But to address your original scenario: >Did I do my math correctly in seeing that my max CFM requirements are 175 CFM's? Not quite. It would vary by room, but I'll use just one example. *Minimum* (not maximum) CADRs for the living room would be calculated the following way for [AHAM's 2/3 rule](https://ahamverifide.org/ahams-air-filtration-standards/). 2,160 cubic ft. ÷ 8 ft. = 270 sq. ft. as the "adjusted" purifier coverage rating. Then, 270 sq. ft. ÷ 1.5 = 180 CFM. Minimum CADRs for the living room would be 180 CFM. However, we generally recommend higher CADRs if you have allergies or asthma to reduce the severity or onset of symptoms. And since you want to run purifiers at a lower speed anyhow, oversizing would definitely be recommended. Unfortunately many brands do not list CADRs for airflow speeds/settings other than the highest one. Lower speeds have lower CADRs of course. ➡️ I would definitely recommend the [**Coway Airmega 240**](https://cowaymega.com/products/airmega-240) instead of the Airmega 250. The Airmega 240 is quieter, cheaper, more energy efficient, and has higher CADRs. If you really wanted to oversize, I would recommend the [Coway Airmega 400](https://cowaymega.com/products/airmega-400). The top-of-the-line and very quiet [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox) is a fantastic price (in Mocha Beige only) right now, but it would be very big. If you want to calculate energy costs, use this [U.S. DOE Appliance Energy Calculator](https://www.energy.gov/energysaver/estimating-appliance-and-home-electronic-energy-use). Unfortunately most Coway purifiers aren't discounted right now. But sale prices pop up very frequently. Check back daily. Additionally, you can also utilize discount codes like **FORYOU10** or **COWAYMEGA10** for 10% off even on discounted models (most of the time).

There are some Black Friday \[BF\] deals already, but I think there may be more to come in the week leading up to Thanksgiving or BF. I would generally recommend **Coway** first. They're one of the highest quality consumer-grade brands. I think their larger and more powerful models may not be discounted yet. * Four bedrooms, 1,400 cubic feet: [Coway Airmega 250](https://cowaymega.com/products/airmega-250) \[discounted\] or [Coway Airmega 240](https://cowaymega.com/products/airmega-240) \[currently out of stock from Coway\]. * Master Bedroom: [Coway Airmega 250](https://cowaymega.com/products/airmega-250) or [Coway Airmega 400](https://cowaymega.com/products/airmega-400) \[full price; likely will be discounted closer to BF\] * Living Room, \~2,160 cu. ft.: [Coway Airmega 250](https://cowaymega.com/products/airmega-250) or [Coway Airmega 400](https://cowaymega.com/products/airmega-400) * Open Space, \~12,600 cu. ft.: no single purifier will cover this space. You would need *two* [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox) units to meet AHAM 2/3 rule minimum CADRs of 1,050 CFM. Obviously nowhere close to your budget anyways, but don't buy the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox) at full price ($999). It could drop to $619 - $649. For the open space, you may want to consider large DIY Corsi-Rosenthal boxes with [MERV](https://www.epa.gov/indoor-air-quality-iaq/what-merv-rating) 13/14 furnace filters and PC fans. We generally recommend the [3M Filtrete MPR 1900 MERV 13](https://www.filtrete.com/3M/en_US/p/d/b00039899/) (1-inch deep) filters for C-R boxes. A guide is here: [https://itsairborne.com/pc-fan-corsi-rosenthal-guide-a611dabf7e0c?gi=a61b9774d0dd](https://itsairborne.com/pc-fan-corsi-rosenthal-guide-a611dabf7e0c?gi=a61b9774d0dd) A less DIY approach would be to buy several [AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro) units. It uses Efficient Particulate Air (EPA) E11 filters. Top composite CADR for the CARB-certified edition is 413 CFM.

If you have high levels of particulates *and* gases/vapors/odors/VOCs, you really need two types of purifier. Most common purifier brands have very little sorbent media for gases, vapors, or odors (includes VOCs). Sorbent media are activated carbon, activated alumina, or synthetic zeolites. On the other hand, heavyweight sorbent media purifiers clean the air more slowly than particulates-focused units. This is due to "dwell time"/"residence time" and the thick sorbent media beds. As a result, "delivered" airflows are lower and particulates aren't removed as efficiently or quickly. Unfortunately you budget is probably too low for conventional HEPA purifiers + sorbent media purifiers in each room. # Particulates units You'd have to oversize conventional HEPA purifiers for quieter operation and high CADRs due to asthma & allergies. This would be very expensive. For example, the open concept Living/Dining/Kitchen space needs a minimum of 305 CFM CADRs. You'd have to go with something like the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox) for sufficient CADRs and quieter operation. (I don't recommend buying the Airmega ProX at full price.) The Bedroom needs bare minimum CADRs of 102 CFM. I'd recommend the [Coway Airmega 240](https://cowaymega.com/products/airmega-240) \[currently out of stock; should be back somewhat soon\]. **Corsi-Rosenthal Boxes & Similar** If you want to save money, you could try building large Corsi-Rosenthal boxes with [MERV](https://www.epa.gov/indoor-air-quality-iaq/what-merv-rating) 13/14 furnace filters and PC fans. PC fans are much quieter than a box fan. CADRs will depend on airflow speed, # of PC fans, # of filters, and filter size. You may want to add a fine mesh pre-filter overtop the MERV filters to catch coarse particulates like dog hair and visible dust. Cheap [3M Filtrete MPR 2500 MERV 14 filters in a 4-pack can be found at Costco](https://www.costco.com/p/-/filtrete-air-filter-1-mpr-2500-merv-14-high-performance-premium-allergen-ultrafine-particles-bacteria-and-virus-filter-4-pack/4000181409). A guide: [https://itsairborne.com/pc-fan-corsi-rosenthal-guide-a611dabf7e0c](https://itsairborne.com/pc-fan-corsi-rosenthal-guide-a611dabf7e0c) Alternatively, have a look at the [AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro) for each room. It uses Efficient Particulate Air (EPA) E11 filters, which is two filter classes below HEPA H13. Top composite CADR is 413 CFM, but this may be quite loud for you. # Vacuum Choose a bagged vacuum with a HEPA exhaust filter. This is superior to many (if not all) bagless or cordless vacuums. I have the [Miele Classic C1 Pure Suction HomeCare PowerLine - SBCN0](https://www.mieleusa.com/product/11262170/canister-vacuum-cleaners-classic-c1-pure-suction-homecare-powerline-sbcn0-autumn-red). It cut down on my runny nose while vacuuming. **Caveat**: the supplied AllTeQ SBD 365-3 floorhead will *not* work with long hair, whether human or animal. My floorhead's axles have hair wrapped around them; now the wheels won't turn. I had to buy the [TurboTeQ floorbrush (STB 305-3)](https://www.mieleusa.com/product/10455360/turboteq-floorbrush-stb-305-3) for this purpose. # Gases/vapors/odors/VOCs units For gas range or gas stoves, a ducted exhaust range hood would be ideal for cooking-related pollution. But I'm guessing you're in a rented space, so upgrading the range hood is likely not feasible. **To figure out which VOC "species" are in your air, you'd have to do testing with Gas Chromatography-Mass Spectrometry (GC-MS) analysis.** Many sorbent media purifiers use plain or chemically untreated activated carbon. The problem is that plain or chemically untreated carbon (or other sorbents) do *not* have high removal efficiencies for all gaseous "species". Sometimes you need to modify sorbents (via chemical impregnation) to improve these removal efficiencies. If you were to use plain sorbents only, you could run into some unwanted problems. E.g., "sweet" odors emanating from the activated carbon filter which may be the not-well-adsorbed acetaldehyde or spikes on tVOC monitors despite a reduction in odors. Even impregnated sorbents have their issues, especially those that break down certain gases. Depending on the exact air chemistry, these oxidizing sorbents may produce problematic byproducts. (Typically this is an issue in totally unknown or highly complex air chemistries, e.g., wildfires or fires in the built environment.) An example of an oxidizing agent is potassium permanganate (KMnO₄) used to impregnate activated carbon or alumina. KMnO₄ can off gas as it saturates or loses efficacy. **Heavyweight sorbent media purifiers are very expensive, VERY loud, and clean the air more slowly than particulates-focused units.** An example entry-level unit is the [AllerAir AirMedic Pro 5 which has a 14 lbs. VOCARB carbon canister for $594.98](https://allerair.com/products/airmedic-pro-5?variant=11868544892972). AllerAir's standard option carbons are plain/chemically untreated. You'd have to contact them first for customized carbon blends based on your air chemistry.

You could have mold growth behind the walls and above the ceiling, hence the mustiness. Have you contacted your landlord? [Here's an article about range hood types](https://www.kitchenaid.com/pinch-of-help/major-appliances/types-of-range-hoods.html) (not an endorsement of this brand). Yours may have [baffle filters](https://cosmoappliances.com/wp-content/uploads/2021/03/668ICS-668A-AS-668WRC-WRCS-RS.jpg) or [mesh filters](https://broan-nutone.com/getmedia/59639005-28ec-46eb-86b7-1c778e442632/SB08087153_1.jpg). Clean them according to the owner's manual to maximize airflow and grease capture. For the living room, you could upgrade to the [Coway Airmega 250](https://cowaymega.com/products/airmega-250) or the [Coway Airmega 240](https://cowaymega.com/products/airmega-240) \[the latter currently out of stock at Coway, but a very good model\]. Having an oversized purifiers means more versatility in terms of choosing quieter yet still (probably) sufficient airflow speeds. For the kitchen, it may depend on cooking methods and frequency. You could stick with the [Coway Airmega 160](https://cowaymega.com/products/airmega-160?variant=40477296394399) or again go a bit bigger with the Airmega 250 or Airmega 240, assuming you have the physical space to do so. If you want to order directly from Coway, try using the discount codes **COWAYMEGA10** or **FORYOU10** for 10% off. They may not work on Black Friday deals, but could work at other times or for other models.

Definitely avoid the PuroAir pictured here. It's astroturfed to death, not high quality, and the [company tried suing a legitimate review website for an unfavorable review](https://www.youtube.com/watch?v=RNonfByE9xc). I *wouldn't* buy the Dyson recommended by someone else either. Dyson is known for glossy marketing and poor performance for many of its purifiers. The HushJet has a top Clean Air Delivery Rate (CADR) of 131 CFM. Even on sale it's $299.99! That's ridiculous. See the AutoModerator comment. Purifiers aren't good at reducing *visible* dust as it's large and heavy compared to invisible pollutants like PM2.5. See our FAQs wiki page entry ["What else can I do to reduce dust?"](https://www.reddit.com/r/AirPurifiers/wiki/index/faqs/#wiki_what_else_can_i_do_to_reduce_dust.3F) for other strategies. Most common purifier brands don't have much activated carbon or other sorbent media by weight for gases/vapors/odors/VOCs. Instead, they're designed for capturing particulates. 700 cubic feet would be the result of a room's length × width × height. If I divide 700 cu. ft. by a hypothetical 8 ft. ceiling, this would give me 87.5 sq. ft. Minimum CADRs for a 700 cu. ft. room would be 59 CFM. Coway is typically our first recommendation for a high quality particulates air purifier. Normally I would recommend something like the [Coway Airmega 240](https://cowaymega.com/products/airmega-240), but it's been out of stock for some time in the USA. Good alternatives would be the [Coway Airmega 150](https://cowaymega.com/products/airmega-150) or [Coway Airmega 160](https://cowaymega.com/products/airmega-160). Either model has a top Smoke CADR of 153 CFM. Models like the [Coway Airmega Mighty AP-1512HH](https://cowaymega.com/products/mighty-ap-1512hh) or [Coway Airmega 200M](https://cowaymega.com/products/airmega-200m) have higher CADRs, but tend to be fairly loud. If you want to order directly from Coway, use the discount code **COWAYMEGA10** for 10% off.

Per the [AHAM 2/3 rule](https://ahamverifide.org/ahams-air-filtration-standards/), a 100 sq. ft. office with an 8 ft. ceiling needs *minimum* CADRs of 67 CFM. If you experience wildfire smoke conditions, the Smoke CADR needs to *equal* the room's area, so a Smoke CADR of at least 100 CFM. Unfortunately most brands only list CADRs for the highest airflow speed/setting only. Therefore you need to definitively "oversize" a purifier to (hopefully) achieve sufficient CADRs on lower speeds. Coway is a very good brand. The [**Airmega Mighty AP-1512HH**](https://cowaymega.com/products/mighty-ap-1512hh)**\*** and [**Airmega 200M**](https://cowaymega.com/products/airmega-200m)**\*** are good value for money, although they will be too loud to run on the highest airflow speed or setting. They're also less energy efficient per CADR than some of the more expensive Coway models. Both models also have an optional bipolar ionizer. Turning off the ionizer may reduce one or more particulate type CADRs. Occasionally the Mighty or the 200M develop fan balance issues (e.g., abnormally loud operation and "walking" across the floor). **\***I've used the USA Coway website as the Canadian site doesn't have product pages for these models. If you wanted to stretch your budget a bit, consider the [**Coway Airmega 240**](https://cowaymega.ca/products/airmega-240). It has higher CADRs, should be quieter, and is more energy efficient than the Airmega Mighty AP-1512HH or Airmega 200M. If you order from Coway Canada, use the discount code **COWAYMEGA10** for an extra 10% off. That brings the price down to $348.71 CAD with estimated taxes.

This user must be a bot or using AI. They told you get to "true HEPA", but recommended the [Smart Air Sqair](https://smartairfilters.com/en/product/sqair-air-purifier/) which doesn't use HEPA. It uses an Efficient Particulate Air (EPA) E12 filter. And the Sqair does not have "higher CADR and better filtration" than the Airmega Mighty 1512HH. Someone's welcome to correct me here, but I've *never* seen any Blueair Classic models with only "HEPA" filtration as opposed to Blueair's "HEPASilent" technology. And then they recommended an IQAir HealthPro. Even if your budget "isn't tight", the [IQAir HealthPro Compact XE](https://www.iqair.com/ca/products/air-purifiers/healthpro-compact-air-purifier?Model=XE) is $1,584.99 CAD!

If you need to filter particulates (e.g., smoke particles) *and* smoke gases/vapors/odors/VOCs, you really need two types of air purifier. Most common purifier brands have very little activated carbon or other sorbent media by weight. They are designed to capture particulates quickly. You need many pounds of sorbents for longer-term or high concentrations of gases/vapors/odors/VOCs. Heavyweight sorbent media purifiers are very loud, very expensive, and clean the air more slowly than particulates-focused units. This is due to the need for "dwell time"/"residence time" and the thick media beds. If you're in a country outside of the USA and Canada, you have fewer choices for sorbent media purifiers. Usually the only choice would be the IQAir GC or GCX series units, specifically models using potassium permanganate (KMnO₄) impregnated activated alumina. KMnO₄ improves the removal (via redox reaction) of formaldehyde.\* As for VOC or PM2.5 sensors, most consumer-grade purifiers use very cheap and inaccurate ones. I would invest in a standalone AQI monitor like the [PurpleAir](https://www2.purpleair.com/products/list) (Flex or Zen models) or the [AirGradient ONE](https://www.airgradient.com/indoor/). These are more accurate. Of the brands & models you listed, the Coway Airmega 200M would likely be best. I'm unsure if other Coway models are offered, but I would more strongly recommend the Coway Airmega 240, Coway Airmega 250, or Coway Airmega 400 if they are available to you. \*As an oxidizer, KMnO₄ has the potential to produce problematic byproducts depending on the gases in the air. This is usually an issue with highly complex or unknown air chemistries (fires in the built environment or chemical spills).

I bought a Coway Airmega 240 for my 1br apartment and even before the smoke the biggest thing I've noticed -- and I'm sorry if this is weird -- is that I *enjoy* breathing in my apartment? It's the first thing I do when I get home, like I'm stepping out into the Swiss Alps for the first time. And waking up in the morning, my throat is less dry. I also don't have to dust as much! I was worried that I'd spent all that money on something that I'd barely notice, but I would say that it's been worth it. And my power bill only went up by a dollar!

After lots of research I finally decided I wanted to get the Coway Airmega 240 purifier, only to find out it’s sold out on Coway’s website and most other seller’s websites. I did find it at Target for $299. Right now the 250 is on Black Friday sale on Coway’s website for $240. I know the 250 has lower cleaning rates (I don’t remember the exact terminology 🤦🏼‍♀️), and is louder. Do you think the discounted price would make it worth it to get over the 240? I’m planning to get two to use in my 1200 square foot house, primarily to help with allergies and eliminate potential mold spores (I don’t have any leaks or visible signs of mold). I just don’t know if the lower cleaning outputs would make THAT much of a difference, or if the louder model would be THAT much more annoying. Any insight would be appreciated!

Thank you! That’s good to know. I went ahead and ordered two of the 240s!

I'm sorry! I actually ended up returning one of them, so maybe try keeping an eye on this link to see if they add it back to the listing?
