Air Purifiers for Large Room Whole Home Up to 2,640ft², True HEPA Filter for Smoke, Allergies, Pet Dander, Odor, PM 10 AQI, Turbo Eco Mode, Timer, Energy Star, 3yr Warranty, Airmega 350 Beige

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.

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.

The Coway Airmega is amazing! Super quiet, sleek design, and it really makes a difference in air quality. I noticed the air feels fresher within hours, and my allergies have improved a lot. It covers a large area perfectly and the smart features (like air quality indicator and auto mode) make it effortless to use. Filters are easy to change, and the overall build feels high quality. Definitely worth the investment if you care about clean, healthy air at home.

I just got the 350, so far it has been performing incredibly well. 1: the CADR is overkill for my space (~400 sq ft) which means it typically stays pretty silent. I find the auto feature to be pretty sensitive which means it'll kick on pretty quickly if I'm cooking or taking out the trash, etc. There is a feature to calibrate this as well which is really nice. 2: it’s the first time I’ve been able to cook without setting off the alarms. Might have just been a coincidence, but after I set it on turbo it was able to clear the apartment and go from “unhealthy” to “healthy” in about ~20min. 3: it uses activated pellet carbon vs mesh/fiber which is nice. However, they haven't released the exact weight of the carbon yet, but I'd assume (based on their other models) the base filter has around ~0.40 lbs (+/- 0.20) of carbon. 4: it’s aesthetically pleasing and fits within my small apartment. Very quiet, and even on turbo I find it not too loud and I can still watch my shows right next to it. 5: it fit my price point. If you're debating what air purifier to get, I’d stack rank your “must haves” and “nice to haves” and just compare it from there. I didn’t really care about an app, I wanted high CADR, I wanted something from a trusted brand that also has the filtration type I want. And it needed to be relatively quiet and not an eye sore. Like, yeah, if I spent $1,000 I could get the perfect unit. But I don’t want to spend that. I also think you start to get diminishing returns.

Minor annoyance: When I went to register for the product warranty, the serial number was not recognized on the coway website. Finding support on the website is something of a runaround also, because there is no web based support form. All support is via email. So I sent the serial number and requested warranty registration to the support email. Happily, the email request for product registration was answered the next morning, very prompt IMO. Initial impressions: This thing is a beast. I ran it on high overnight and the air is notably fresher the next day. It is notable loud in high mode though, so we'll see how auto mode does, and we'll see if the sensors hold up over time. 3 year warranty so fingers crossed. Another note: this model does not have WiFi, so there was a moment of frustration before I realized that. Not a real concern for me, but just be aware in case it matters for you
