"My air purifier for months was red and I figured the light was broken because I wasn’t experiencing any symptoms (no sneezing, runny nose, watery eyes) and I’m allergic to everything. ... Then we discovered mold on a shelf. Threw out the shelf, air purifier turned blue and no more issues. So it was definitely doing its job!"
"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."
"this thing has been amazing!!! ... I have two kids with seasonal allergies and this thing has been amazing!!!"

"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."
"the air monitoring report and air quality sensor. I've had a home improvement project going and as soon as dust started flying the air filter on auto setting cranked all the way to the max to counter."

"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."

"It's still not providing 4-5 air changes an hour to 3,000 square feet ... It's common for air purifier manufacturers to mislead on square footage coverage. The 3,000 square foot is likely based on one air change an hour. That won't be enough for someone wanting a purifier to help with allergies, viral load reduction, dust reduction, etc. ... The Blue Air website recommends 635 square feet for 4 air changes in an hour. ... The 635 square feet assumes the device will be ran on the highest fan speed to achieve the 4 air changes an hour. ... After doing some deeper digging I learned not to trust the advertised square footage. Even some big name publications are just trusting manufacturer claims and are not doing their own testing to verify. Members of this forum like myself try to educate people that we can't always trust the advertised square footage. ... It's unfortunate we can't always trust the advertising. I wish manufacturers would give a straightforward number on air changes you can expect in an hour within a certain square footage and ceiling height. For ex: 4 air changes an hour in 500 square feet 1 air change an hour in 2,000 square feet"
"Energy Star rates the Coway Airmega 100 for 169 square feet. ... Sadly it's very common for air purifier companies to overinflate their room size coverage. ... Energy Star and the Association of Home Appliance Manufacturers are great sources for seeing the recommended room size. Even then, the room size is based on the highest fan speed. Sometimes there can be big differences among the different fan speeds."
"However, it claims to have 3500 sq foot of range but it doesn’t have the best range as I disconnect once I get to my front door. The router is upstairs with nothing directly blocking 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.."

averitablerogue 1.0I have the Coway AP-1512HHS (the app-enabled Airmega, there’s also a dumb version that can’t connect) that I use via a HACS integration.
Such_Entertainer_854 1.0the new coway 1512hhs wifi no ozone but noise wise i recommend alenair 35i level 2 or 3 is quiet and gets 125 cfm and is prolly quietest for the cadr - check housefresh review
Agent_03 0.2Sorry, 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.
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.
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/)
AndrewLAFan14 0.2Coway Airmega AP-1512HH has been my go-to for a couple of years. It’s compact, quiet, and works like a charm for medium-sized rooms (up to 361 sq. ft.). The 4-stage filtration system (pre-filter, HEPA, carbon, and ionizer) is super effective at removing dust, allergens, and odors. I love that it has an eco mode to save energy when the air quality is good. It’s reliable and low-maintenance.
Ashamed_Bike_7453 0.2I second Coway. I have the [Coway Airmega AP-1512HH](https://www.reddit.com/r/ApplianceAdvice/comments/1cx5tt5/best_air_purifier_to_buy/) and it is a fantastic air purifier to improve indoor air quality. It's quiet, efficient, and has a sleek design that blends seamlessly into any room.
AtticusScout 0.2I’m loving what I’m seeing about the coway 1512, already bought one for my bedroom. Thanks for the recommendation! For two smaller rooms would you still go for that over the coway 100? Wasn’t sure if the 100 was good enough since the rooms are smaller and I failed to mention I have 2 boys in the smaller room and my daughter has used up all available space in her room so the smaller the filter the better lol. But if the carbon filter is especially better she can move some of her dolls around to make the space for the 1512. For the winix c909 is there a reason you suggest that over coway? I saw one comparison with the 5500 that said it has a better carbon filter and does better with VOCs but the c909 I’ve read doesn’t have as good as a carbon filter and I’m having a hard time figuring out how it compares to coway
Brilliant-End4664 0.2Coway Airmega 350, Winix 5500-2 and Coway Airmega 1512.
Winix 5500-2 or Coway Airmega 1512
Winix 5500-2 or Coway Airmega ap-1512hh
Winix 5500-2 or 5510. Also Coway Airmega ap-1512hh
With the Winix yes. It has a feature called Plasmawave which you can turn off. Coway doesnt have any ozone. I have an 8 month old, and the Winix hasn't bothered her at all. We keep plasmawave on all the time.
cocoa_boe 0.2I just bought the coway airmega ap-1512hh. It was wirecutter’s pick, the amazon reviews were positive, done. I have a new apartment so been buying quite a bit and couldn’t be bothered to go down a rabbit hole of comparing fifteen different products. It’s working well. I do wish it was WiFi enabled. But I bought it for pretty much the same purpose, improving the room smell as I have a very elderly rabbit who no longer uses his litter box. They have a special pet filter but I decided to try out the one it came with for a few days and see if I felt it was necessary - it wasn’t. I don’t think any one air purifier can do the whole house unless it’s attached to your HVAC system. I’m probably going to get another one for the bedroom.
D3skL4mp 0.2You’ll typically see the same top-rated models across Wirecutter, Consumer Reports, and Tech Gear Lab: the BlueAir Blue Pure 311i+ Max, Coway Airmega 1512HH, and Winix 5500. The best choice probably depends on the size of the space you’re trying to cover. For my downstairs rooms, I went with two BlueAir units (the 311 and 211 models). BlueAir offers a 25% discount for teachers, military, police, and possibly firefighters (can’t recall for sure), available in both the U.S. and Canada. They also offer a 15% discount on filter replacements if you sign up for a 6-, 9-, or 12-month subscription. For my upstairs office/bedroom—since it’s a smaller space—I went with the Coway Airmega 1512HH and have been happy with it.
demoorigin 0.2Coway is regarded pretty highly I just bought an airmega 400 but something like the airmega 1512 has been a top performer in its class and it's on a sale RN for 165.
