Airmega 200

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/)

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.

Absolutely love our Coway Airmega 200M. In fact, will be buying more shortly.

I have been running a Coway Airmega 200M for about three years now and it genuinely makes a noticeable difference with smoke and cooking odors. The key with smoke is you need a HEPA filter combined with activated carbon because HEPA alone catches particles but the carbon absorbs the volatile compounds causing the smell. In your budget the Coway and the Winix 5500-2 are probably your best bets for actual performance rather than marketing claims. How big is the room you are trying to cover and is the smoke coming from outside or inside?

These worked very well for me when my area was inundated with smoke. My house is old and porous, so it was fairly smoky inside without them. I started with one that I would move with me from room to room. I now have 3 plus one smaller model. Edit: Coway has another model that is exactly the same but with a nicer looking front plate. I think it might be the 200?? I don’t know for sure. It takes the exact same filters as the 1512.

I have a Whirlpool Whispure that is about ten years old and has performed well, but I think you can get a similar sized Conway Airmega 200M for about half the price, and they are very well rated. A full filter set lasts for a year, you change the carbon prefilter every three months. The filter set will cost you about $35 each year.

I have the Coway Airmega 200M in my office which is approx 10x12. I also have an AirGradient indoor sensor. My particulate readings with the air filter are almost always at 0 for PM2.5, PM0.3 and PM1 readings.

How many sq. ft? Coway Airmega 200M or 250. Winix 5500-2. Yes they will help a lot for allergens and odors, as long as you clean the pre-filter weekly, replace the carbon filter every six months, and replace the HEPA filter every year.

I love my Airmega 200's, but they're so loud on high :(

it is a nice white noise, remember to hold the Ionizer button to turn off the light at night :)

The NYT just did a review and ranked the Coway Airmega 200 as the best air purifier. They're under $200. I bought two and like them a lot so far. They have an ionizer, but you can turn it off. They're quiet and move a good amount of air. There are two types -- one has a large circular front and sucks in air around the edges of the circle, and the other is a regular rectangular front that sucks air in across the entire front. I have the rectangular front model. They also have a good handle for moving it around. I really liked the Honeywell HPA300 (I think that was the model), but they stopped making them. The ones they sell now look similar but are about 1/3 bigger, and don't perform any better. I feel like the bigger model is really weak at lower levels and only works well on turbo, which is really loud, while the older models worked better at lower levels. And it's just way too big for the average room and has no handles for moving it around. I have one of those cylindrical Levoit purifiers, and it works fine but I don't like how it only sucks in air at the bottom 1/3 of the purifier. A lot of the bird dust I get (I have a grey) is floating much higher in the room.

Ahh I was thinking about the small Airmega 200M. It's functionally the same as the mighty (which I actually have but prefer the look of the newer airmega). I've had it for 9 years and it's been great.
