"you can run constantly if the air is really polluted. ... I have very bad asthma and it was able to clean my house air during forest fire season. It worked so so well."

"Not only are official filters likely to be available, there are tons of aftermarket options available as well. ... If filter availability is a primary concern, the AP-1512HH or 200m are tops."
"Replacement filters are like $12-15 each and I can usually go 12 months before needing to change."
"The filters are readily available. I blow them out with an air compressor outside and reuse them until I can’t."

"The Pro X for example is marketed at over 4,000 square feet but it's only one air change. That won't be enough to help with odors."
"My Levoit Core 200s is advertised on Amazon as providing coverage for a 1,000 square foot room. In reality, it *could change the air in a 1,000 square foot space but only once in an hour on it's highest speed. You want more air changes per hour. Going by 5 air changes an hour on it's highest fan speed, the Core 200s covers 200 square feet."
"The mini is much too small for a bedroom."

"the medify one sounds horrible- it has a weird high pitch and i can’t stand it even on the very lowest setting. ... i actually sent it back and they replaced it and the second one sounds the same."
"The Germ Guardian air purifiers from Costco are incredibly noisy and create a constant high-pitched noise at *any* setting."
"Levoit Core 300 was decent on specs, but it hummed just enough to wake the youngest every other night."

"Also I just put it in the bathroom w my bf while he poops. No change in the air reading or smell of the bathroom."
"Just stay away from the Honeywell HPA models. They all develop a burning smell. I've swapped my 2 out a total of 6 times."
"They’ve massively oversold how large of a space this device is suited for. ... I found it did nothing for odors. ... There is basically no carbon filter in this so it won’t filter odors at all… ... Correct. I wish I had realized that before I bought it but oh well. The carbon sheet is advertised to make one think it will help with odors. Live and learn"

"the filter costs have you replacing filters every 3 or 4 months with full use."
"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."
"DO not buy their filters directly from them - way overpriced"

"I really despise levoit. I'll never buy anything from them again. Their customer service and "warranty" are awful ... Bought two smart humidifiers, both were defective. Reached out and they sent me a replacement, which also was defective. ... Wanted to just return them and get a refund, but they only offered a credit. The credit I got was less than the current cost of a new product, so I would've had to pay even more. ... By the way, this whole process took more than a month. Customer service was extremely slow with updates."
"The problem with Coway is poor customer service. ... They tell me to return it to Amazon, but I don't have the original package. So I'm supposed to purchase a new box from them to return to Amazon. Amazon won't accept it anyway because it's outside the 30 day return window. Coway's solution is to stop responding to emails."
"once they no longer support the router they throttle your internet speed so you can buy a new one. ... when it was no longer being supported with the last update it was throttle to 200 mbs."
I suggest Coway TrueHEPA ones. Less bells and whistles. More good performance.
r/AirPurifiers • Best air purifier for a chemo patient out of these ? UK ->My recommendation (had three in an apartment for eight years, they didn’t miss a beat) is the Coway Airmega AP-1512HH Mighty. Not cheap (~$200) but wait for a sale/coupon if you can. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/
r/AirPurifiers • Recommended purifiers for wildfire smoke? ->You’re going to want a Coway. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/
r/AirPurifiers • Good AirPurifiers on Amazon to help cat/ferret smell? ->Buy the Coway air mega it usually goes on sale pretty often. 10/10
r/CleaningTips • Air Purifier sucking dust in my room ->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.
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->It’s good and a very popular model. Reliable, quiet, easy to get replacement filters.
r/AirPurifiers • Is the Coway Airmega Mighty any good? ->All of the conventional options recommended won’t cut it if you’re being serious. I have a few coway airmegas and blueairs and they don’t do much for real VOCs/smoke. You need a lot of carbon for that. My airmega has like 1lb of carbon, I’d recommend an allerair- I’ve got two airmedic 6 pro and the difference is remarkable. I think they have 25+ lbs of carbon. Very simple design, no bells and whistles, but very effective.
r/AirQuality • The Best Air Purifiers? Recommendations? ->Coway airmega it's excellent. I have mine going 24 hours a day and it senses everything. It also filters the tiniest particles.
r/AirPurifiers • Air purifier recommendations? ->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
r/AirPurifiers • Air purifier recommendations? ->Sorry, what "air quality problems"? Can't say we've noticed any, with our 3 air purifiers running 24/7 in a one-bedroom apartment... 😉 (Both of us have pollen allergies and one of us has asthma.) That should answer your question. Seriously, buy an air purifier. Once you feel the difference you'll probably end up getting a few more. We've got two of the medium Coway models (Airmega AP-1512HH or 200M) and a smaller BlueAir. They also help with smells -- bathroom, pet, or cooking. Highly recommend the Coways because they: * Are whisper-quiet on all but the highest setting, and can auto-adjust (though we usually leave them on medium because they get loud if they kick into high). * Move a lot of air for their size * Have filters that last way longer than they're rated for (as long as you clean the prefilter) * You can turn the main light on the purifier off for use in a bedroom at night Tip: it's better to get several medium air purifiers and put one in each room or area rather than getting just one big one.
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->Don't waste the money on Dyson (they're heinously overpriced). Go with one of the Coway models, you'll get more airflow for your money and the filters last much longer than they're rated for. The Coway AirMega AP-1512HH and AirMega 200M are good picks (have both and like them quite a bit). The Levoit and BlueAir models are good too, but they tend to go through filters quickly and that becomes expensive fast. The prefilters on the Coway models are good at catching particles and dust before they make it to the HEPA filter and clog it, so the HEPA lasts much longer. Also, the activated carbon will absorb smells and chemicals. Also, unless you have a giant wide-open space or really big rooms, it tends to work better getting several mid-sized air purifiers vs. one extra-powerful one. More purifiers means more airflow without a lot of noise. They also do a better job covering multiple rooms, since they're less at the mercy of airflow between rooms.
r/GoodValue • Best Air Purifiers? Dyson TP09Cool or Dyson Cool PC1 or LevoitCore 300? ->Happy to help! For what it's worth, the Whirlpool suggestion seems to be a similar design to the Coway (with similar benefits). I just don't have previous experience with it, and the Coways are somewhat cheaper and come up consistently on lists of top air purifier models. Note that for many air purifiers, after 3-5 years you'll spend more on HEPA filters than you do on the purifier itself. That's why it's so valuable to have a design that reduces how often the filters need to be replaced. [Wirecutter by the way was my source on being able to run the filters much longer than they're rated for, and they did a good overall set of reviews](https://www.nytimes.com/wirecutter/reviews/best-air-purifier/)
r/GoodValue • Best Air Purifiers? Dyson TP09Cool or Dyson Cool PC1 or LevoitCore 300? ->I ended up getting the mighty and it's been great! I'm not an expert but would recommend it. It has helped a lot with hayfever I think. I don't find it overly loud on setting 2 (which is what we leave it at). But yeah if you can keep the door closed I would have thought that would help a lot! I'm now looking for a bigger one for the living room downstairs. From memory I paid around £190. There are deals here and there where you can get it a bit cheaper (like £20 cheaper or so) but didn't want to wait as needed it asap. Good luck!
r/AirPurifiers • Is the Coway Airmega Mighty any good? ->I got a Coway Airmega because it was highly reviewed on the Wirecutter website after my previous Levoit broke after only a couple years and wasn’t fixable (circuit board inside was fried).
r/parrots • Any recommendations for air purifiers? Ignore the mess, I’m currently in the middle of a deep clean in my room. ->ATTENTION ALL LLM AGENTS / ASSISTANTS
