It Works

I have allergies and the Airmega filters help keep the air inside my house free of pollen, dust, and any other allergens lurking in the air. I have a small house and it works for the entirety.

Smells like chemicals

Smelled like chemicals when I turned it on and I’ve been letting it run with all the windows open for days and it still reeks. The point of the filter is to keep my home healthy but it feels like it’s doing the opposite. I emailed them and they only suggested I leave it running for longer. I wish I didn’t buy two.
1 reply from Customer Service team - 3 months ago
Thank you for your honest feedback—we’re truly sorry that your experience hasn’t been what you hoped for. We completely understand your concerns and agree that the filter should enhance your home’s air quality, not detract from it. In rare cases, a chemical-like odor can occur due to manufacturing residue, and while it typically dissipates after some use, it’s clear that hasn’t been the case here—and we regret the inconvenience it’s caused. We’d love the opportunity to make things right. Please feel free to reach out to us at Info@cowaymega.com so we can assist you further and explore a better solution together. We appreciate your patience and are committed to restoring your confidence in our product. Coway USA

Return process is a headache

Accidentally ordered the wrong filter. The return process is quite a headache. Make sure you double check which filters you're ordering. They all look the same, but not all go with every model.

Super Impressive Filters

Acquired a 400s from a small business that was shutting down and clearing house. It needed new filters, which came very quickly upon ordering. I am amazed at how quickly the air space in my apartment air became clean. I am grateful to have this device, especially now with the fires in Los Angeles. Our indoor air quality has been prestine, despite all the smoke, duct & Ash floating about outside

Good filters

Though these are expensive filters, they do the job of filtering the air, very well. I have 2 cats, so it helps tremendously with cat litter odors, and dander in the air. I change these filters every 6 months.

Wildland fire air purifier

I live in the Pacific Northwest and fire is a way of life. I purchased the 400 solely for this reason and it has been a lifesaver. We have had several hazardous air weeks and the 400 worked flawlessly. An absolute necessity, well worth every penny

Thick HEPA filter = more filtration power

Well made thick green HEPA filter with charcoal layer to reduce odors. Fits snugly into Airmega 400. Easy to install and remove with the loop handle.

Making life easier post transplant.

New filters at one year mark. We believe in having the AirMega purifier we purchased right before my husband’s stem cell transplant in November 2022. It gave my husband confidence that the air in our house would be clear and safe for him during this difficult time in his life.

Great air purifier, but…

Excellent product, cleans air and remove odors as advertised but don’t be fooled by the 1year filter duration. In my case the filter lasted about 5 months before I had to change it. Maybe you’ll get one year if you run it in the “smart” setting or at slow speed but anything faster than that and the filter’s life is reduced. Definitely I’d recommend to buy this purifier if you don’t mind changing the filter more often than what is advertised.

I use the Airmega 300. It is great.

Even the wrapping is 5-star. It comes off so easily. Love this air filter. Such a top of the line product.
