Testimonial

"I purchased the AiIRMEGA 300 during the Santa Barbara fires last December 2017, when the air quality was terrible for many weeks. It brought relief for my respiratory symptoms due to smoke issues even in my apartment. It has been operating continuously, 24/7, on the Smart Mode ever since. Two weeks ago it quit. I am extremely pleased with the excellent customer service provided by Chuck at Coway. This is a very responsive service supporting AIRMEGA products. After one initial phone call, all communication was by email and was prompt and very efficient. I was emailed a prepaid label to return the malfunctioning purifier via UPS. I received a brand new unit free of charge under my warranty." - Music Lover Forever

Testimonial

"I always purchased the air purifiers with the washable permanent filters and while they worked really well the first couple of days after cleaning them, I have to say I'll never go back again. Even though you have to replace the filters (which btw I'm a cheap a$$) it's beyond worth it. I have a 750 sqft 1 bedroom apartment and while this unit says it will do 300-600sqft it works very well on my entire apartment. I will have many friends over on the weekends to hangout and the majority smoke, I didn't used to allow smoking inside but with this I keep it on auto and it keeps the air clean to the point my non-smoking friends are actually impressed how well it cleans the air. The next morning you don't even smell that stale cigarette smell like I have smelled in the past when I would say screw it and let people smoke inside. I have 3 Oreck air purifiers which I've had over 10 years, while they work okay, the 3 of those can't even compare to what this 1 unit does. I will undoubtedly purchase another one of these if I ever upgrade to a larger place and most definitely would recommend it to any one. I hope this review helps. If you're ever wondering if it's worth breaking down and getting something you have to replace filters on, the answer is yes! Do it! It's worth it and the filters are easy to change. Don't forget that's coming from a penny pinching cheap a$$. This is an amazing product I'm very happy I purchased." - RB

Testimonial

"High price, yet, high quality. This unit exceeded my asthma relief expectations. I mounted this unit on the wall next to my bed in the master bedroom (400 sq.ft.). Now, no more wheezing, coughing, sneezing, or itchy eyes at night or in the morning. I let the Rabbit run all night long on medium speed and I wake up hopping with joy in the morning. I haven't had to use my inhaler at all since I installed this unit in my bedroom two weeks ago. I live in the Silicon Valley Smog Pit and have severe asthma from smog. This unit give me immediate relief. Now I sleep straight through the night. The Rabbit is very well engineered, very well thought out, and quietly delivers amazingly clean air. After two weeks of ownership, I have no observed defects or abnormalities to report at this time." - EagleOne

Testimonial

"We have FOUR dogs in our house. The smallest being 14 lbs. and the largest being 175 lbs. Family stopped coming over because of the doggy odor we went nose blind to. This has solved that. They were very impressed by the difference it made. The largest dog has skin issues that creep up from time to time. When it does, the smell is horrific. This air purifier simply rids us of it spreading throughout the house until we can put treatment on it. It is amazing. I never even heard of this brand of air purifier but rest assured, I will never get any other brand for now on. I’m sold." - Holly Turner

Testimonial

"I have an old home (over 100 years old) and the Air400 has been amazing in terms of improving the freshness (i.e. smell) of my home. I initially put it in the basement and it seemed to work really well to eliminate that "basement" smell. Then I thought that I would try it in my attic which just smells "old". I immediately noticed the basement smell came back once the Air400 was removed, but my attic smells fresh and clean! I have decided to return it to the basement (as it is used more often) and add the Air400 to my future wish list for the attic!" - AC

Testimonial

"I probably purchased a slightly smaller size than I needed - the room it is in is closer to 350' and this purifier said it was for up to 200'. Since we had not had one yet, we didn't want to go "all in" on one for a larger room until we knew if we would utilize it. I have been pleased with with one though. Every once in a while I would smell a bit of a damp odor in our bedroom that I assumed was coming from the adjoining master bath (natural stone tiled shower). We have been using this for almost 2 months and I have not smelled that since and normally would considering our humidity!

The options for high, medium and low are nice. I'm not sure that the 8 hour option works like I thought it would - I thought that if you selected that it would run for 8 hours and then stop for 8 hours etc... but it runs for 8 hours and then shuts off. Which probably makes sense but I couldn't remember to turn it back on! So at night we use the sleep option and hope that one of us will remember to change it in the morning! I think this is a good air purifier for the price and would recommend purchasing it." - Nashville066

Testimonial

"I've purchased four of these True Hepa Air Purifiers (2 for me and 2 for someone else) w/in the last 4 months. As far as I can tell it works very well. I cannot SEE if it's taking in any dust, mold or mites but it sure picks up odors. I live in an apt building and a light cigarette odor was coming into my apt. in the evenings. I didn't keep it on 24/7 (electric bill) but would put it on in the evenings. The light would be blue to start out and around 8p I would begin to smell the cigarette odor and the amber/red light would come on. Shortly thereafter the smell would disappear and the light would go back to blue. ANY, and I repeat ANY, odors and the amber light comes on. When I go into my bedroom at bedtime and turn the 2nd purifier on, the light turns amber even though I don't smell any odors. It must be picking up dust and whatever. I live in New York City and there is LOTS of dust and dirt in the air from all of the construction and traffic! The purifier is letting me know there is something in the air that needs cleaning. The blue light goes on about 10 min letting me know the air is clear. I then put purifier on auto through the night. If I spray perfume or anything, the amber light comes on and goes off once the odor is gone. I also like the different levels of speed that it has. It is quiet until it goes to the 4th level but it's not unbearable. Too bad this model doesn't come in off-white/cream." - Winny B.

Testimonial

"I took a picture of it with my grubby sandle in front of it for size sake. It's fairly quiet, it's "smart" and I'm so glad I bought it. I applied fingernail polish which is pretty stinky and it kicked up to high to clean the air. The lights show you the speed and and your air quality. It seems to be working for my stinky house! I have a fairly small house and I live with a cat and a small dog. I have a carpet, which I never will have ever again, because carpets suck up every bad smell the second you install them. I have asthma so I needed to do something before another winter so I can breathe better. It seems to be working! I bought an extra filter which I won't need for a long time because one can place the filters into the sun to refresh them! I am very happy with this purchase! I would recommend this air filter to anyone! If you have a larger house, you at need two or a larger model. This one came with a True Air plug in wall fan which I put in y kitchen and I love it too. The price is reasonable for this!" - Robin

Testimonial

"This is the third air purifier of this type we have purchased and is the best value of all three. Recently we made a decision to go with a different product that is only a filter. While the product had good reviews the performance was nothing compared to the Green Air Pro. We are very happy with our decision to pay more and get a product which actually removes odors and can cover our entire house (about 3000 sqft of living space). We immediately smelled and felt the difference this purifier makes in our house. Great product. Excellent price. It is also quieter than the last purifier we purchased.
If you are looking for a high performing air PURIFIER look no more and buy this now." - Kevin Gentzler

Testimonial

"This thing is amazing, purchased for my wife due to her allergies - but have found that it works for everything. We placed in living room and once you turn it on (silent/auto) it takes care of it self. example---my wife started to take off her nail polish off, a minute after opening the remover bottom it went from blue (light) silent to red high, 5 minutes after she finished it went back to blue silent on its own. Cooking in kitchen it will go from blue silent to purple med (even with no smoke). This thing has a great sensor that picks up different things going on in home and adjusts. Clears the air quickly and adjusts on its own. It also has a removable front filter that can be rinsed off and then the larger filter pack behind it. Very quite, cool operating and extremely smart. The nail polish remover episode blew me away.
Bottom Line ---- If you are looking for a Purifier for your home THIS IS THE ONE" - Mark Ferreira
