Coway - Airmega 200

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

Second, we've got 2, they're great. The Airmega 200 is basically the same unit too. Multiple smaller air purifiers tends to work a lot better than single big ones.

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.

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/)

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).

They don't really work if you have an active infestation. Ive got 4 lg ones in an 800sq ft house and I swear they do almost nothing. We even have this electrostatic filter in the hvac and still I've get systems when the doors close or the AC goes on. I have 2x airmega 200s, germ guardian rated for 900 sq ft, coway with uv rated for 600 sq ft. 2 upstairs and one down. If I were you id try to build the biggest Rosenthal filter or several as they don't get down hall ways or around stairs, etc. The think I don't like is they really tank your electric bill and are very noisy, as they have to stay on high mode.

Coway 200M is also the same thing with the same filters as the 1512 just a bit less aesthetically pleasing, cheaper and sometimes goes on sale. I got 2 for $158 each recently. Looks like Walmart has them for $149 currently.

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.

firstly-whatever you want a 'purifier' to filter out has to be able to get to, into and through the device. i've yet to see a consumer level air filter that's strong enough to stir dog hair/dander up off the floor. for dust ? they all suck. i'm in colorado, very dusty area. they all suck. any good filter will clog quickly by definition. remember that ;) having said that, i use a coway 'airmega' in my bedroom and i'm fairly pleased w/ it. has a carbon pad for odors, filters out some dust, smoke, etc. they will all have yearly filter costs-generally anywhere from 50-200 bux/yr., mebbe ? none of them that i've seen are anything to sneeze at. ;-p

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..
