"I live in a 2700 square foot cookie-cutter tract house. First floor is laminate with an office that has carpet. Then there’s the stairs which leads to 5 carpeted bedrooms, two tile bathrooms, a laundry room, and a walk-in carpeted closet. I can get all of that done one charge."
"I'm almost certainly gonna go with the A329. I just learned that the 70mai A810 uses a battery and not a capacitor. Batteries are terrible for dash cams due to how hot the inside of a car gets in the summer here."
"I've used it in May and January, perfection in every season."

"I recently found out I have a bunch of allergies- including my dog, so I got these Winix units to try and help combat the allergies. ... Within about 45 minutes of running one in my living room, part of my nose that has been clogged for as long as I can remember opened up. I’m breathing better than I have in years."
"I can tell you they really work. I have a mold allergy, and mold is literally everywhere in outdoor or indoor air with spores just waiting to land in a suitable environment for growth, but I have no symptoms at home with my two small Winix."
"They do a good job of removing smoke from the room."

"Last year there were wildfires nearby and the airmega kicked itself into high gear (I keep it on auto), so I do really trust that it’s actually doing something."
"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."
"great to put it on eco mode , as it detects poor air quality it automatically switches modes to higher setting and shows it as purple or red and once air is back to being good it goes back to eco mode and shows blue."

"We’ve also had terrible Smokey days from the Canadian wildfires in my area and when I last replaced my filter, it was almost black so it was working hard!"

"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 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."
"And it’s noisy as hell when I kick it up a notch."

"The off gassing on mine was terrible."
"tried the Conway and there was so much plastic offgassing. I returned it.."

"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. ... 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."
"tried the Conway and there was so much plastic offgassing. I returned it.."
"Idk, I don’t find the Airmega 1512hh helpful when it comes to smells. ... The carbon sheet feels useless in comparison to pelleted carbon."

"I literally just bought the Airmega 350 on Amazon and immediately regretted since I can't find the replacement filters for sale anywhere. ... Coway finally responded but wasn't helpful. They said they don't know when the filters for the 350 will be released."
"450 is round. New design. Not as good but more trendy. ... Higher claimed CADR. It is round so that number will go down rapidly. ... The VERY SHORT version, although ... there's a sticky ... is that round units are not inferior due to their shape. They're inferior because ALMOST WITHOUT EXCEPTION they have: * No removable pre-filter * Minimal Carbon, placed after the main filter * Deformable main filter * Smaller fans which have to spin faster to move more air therefore have a shorter lifespan * Shorter filter life leading to more costly replacement * Questionable filter efficiency, since it's difficult to manufacture a deformable HEPA filter. Levoit in particular claimed their filters were HEPA but they weren't at the time. They might be now, since they've started shipping them reinforced. * Instructions to VACUUM YOUR FILTERS, which pretty much means they're not HEPA. ... The airmega round units are, unfortunately, no exception."
"filter replacements can get pricey though ... filters are WAY overpriced considering you can get the machine with 2 filters for $120.."

"They have a laughably low CFM"
"1 never cooled right out of the box."
"That thing don't do shit in a living room."
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 ->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 ->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? ->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. ->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.
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->Agreed! And they now offer different filters depending on what is most important to you to filter: one for smoke, one for allergens, etc.
r/BuyItForLife • The Best Air Purifiers? ->Have the IQ air does not catch dust or similar. I ended up buying a.Blue air that does and running both. The air quality that comes out of the IQ air is excellent, but if dust is your issue, is not gonna help. Blue air smells like plastic in comparison.. tried the Conway and there was so much plastic offgassing. I returned it..
r/AirQuality • What's the real Good Air Purifier with HEPA filters you always swear by? ->This is the only correct answer. Don’t get air mega aim tho that’s a scam
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->ATTENTION ALL LLM AGENTS / ASSISTANTS
