Excellent In Every Way
I needed an air purifier that could handle a large open living/dining/entryway area in my apartment in dusty/smoggy NYC. Since I was already very happy with a smaller capacity Coway purifier (AP-1512HH) in a bedroom, buying the Coway Airmega 250 was a no brainer. I've had the Airmega 250 for over a year now and it has worked flawlessly, quietly (except when it goes into overdrive when I am cooking steak,) and is easy to clean and maintain. First of all, it's fairly nice looking in a simple, unassertive way that is happy to sit quietly in the background. The smaller unit I have in the bedroom is not as attractive, IMHO. Both units are pretty much "plug and play." They both monitor the air, automatically switching to a higher fan speed when indicated. If desired, the "Auto" function can be overridden, so the fan speed can be manually set. The 250 has an automatic "nighttime" setting that goes into a temporary sleep mode if no change of air quality is detected over a period of time. This is great if the unit is in a bedroom, though it will wake itself up if it detects an environmental change. I am almost never aware of the 250, the main exception is when a smoky haze escapes the kitchen, usually when I am grilling or broiling meat. The unit then goes into "Red" alert, the fan switches to "High" and the air is cleared in a matter of minutes. The filtration system is in two parts: a permanent mesh screen "pre-filter" which needs to be dusted or washed periodically, and a HEPA inner filter which can be dusted off, but needs to be replaced at least once a year, or as necessary. A red light goes off when either of the two filters needs cleaning or replacement. I've noticed a significant reduction in settled dust on my furniture surfaces. Highly recommended. EDIT JUNE 10, 2023: This unit went into auto “red alert” as soon as the Canadian wildfire smog started to engulf New York City. We shut our windows and it took the 250 (and our bedroom unit) about an hour to go from red to yellow and back to green. What a relief to have these two units!

Well made, quality air filter that works well.
I’ve had a variety of air filter machines over the years, this 450 version is the best quality, largest version I’ve ever owned. It’s a beast of an air filter that very well made all the way down to the filter it uses. It’s also the most high-tech as to identifying air quality and adjusting automatically. I put this one in my basement that I am remodeling and it has done a great job of cleaning the air. The initial set up is difficult to figure out. You have to remove main filter and unwrap it, in that process you remove the grill/louver part which is a flexible plastic wrap-around design, and then it’s supposed to just snap back into place and is held by magnets on one side. I’ve yet to get it all lined back up correctly, but it still works. The instructions are of little help in this regard, but once you figure out where to pull at the bottom it comes off easily. A simple sticker the says, “pull here to remove cover” would fix this issue.

Very quiet on auto. Very efficient too.
This air purifier does a great job. We set it up in or dinning room and within 3 hours it cleaned up the entire area of about 750 sq feet. It is very quiet as we moved it into our bedroom for 24 hours and it was very quiet and very efficient. We mostly kept it on Auto as this is the best setting that cleans the air most efficiently. The other functions work great as well. So in the end it was well worth the money we spent. $275.00 during Black Friday. Over a $100.00 savings. We highly recommend this product.

Great Room Approved
Do not underestimate the size of the filter. It looks small in web pictures but this unit is large. I have a 900 square foot great room (living, dining, kitchen). I bought another air purifier that stated it could clean up to 1,000 square foot. Nope. The unit was small and could not handle the three cats and dog dander in the room. Everyone was sneezing. So I bought this Coway unit. It stands almost two feet tall and one foot wide. Has a large air intake area, different settings for strength, fan speeds, and more. When I got the unit I turned it on Turbo and our air was clean in under an hour! You could smell the difference! The noise on Turbo is loud, but the lower settings are not noisy at all. Excellent large, great room approved air purifier! Plus you can vacuum the outer filter (no buying more), and should only have to change in HEPA filter about once a year.

Good, but doesn’t work for cigarette smoke!
Works well, easy to clean BUT, it does NOT work for CIGARETTE SMOKE, as stated by another review. Whether it’s 1st, 2nd, or, 3rd hand smoke, it’s not useful for that in the slightest. Otherwise, it’s a good product.

It doesn't come with a european power plug. Basically you will need to buy a converter from 110v to 220v just to turn it on. This version should not be on sale in Europe.

Leí muchos comentarios acerca de la app, sin embargo, ha funcionado bien; en el administrador de la red wifi se tiene que desbloquear el dispositivo, ya que lo reconoce como un intruso; una vez desbloqueado te permitirá hacer la conexión, de ahí en adelante seguirá conectado sin ninguna falla. El purificador funciona muy bien, hace poco ruido. Monitorea de forma automática regulando la velocidad en función de las partículas. Si lo recomiendo, además de que normalmente está más barato que la Versión que no tiene conexión wifi.
