Coway reviews and discussion

I have 2 Coway air purifiers now and they have significantly improved my indoor allergy symptoms during the winter, and kept outdoor allergies from bothering me in the warmer months. I have an old house and they also have really reduced the amount of dust.

I started off with just one in my house, but I loved it so much that now I have 3. I had another brand before, but it was wayyy too loud and bothersome to have on even when it was on its lowest setting. For my air mega, I really only hear it if it’s on the max level. I feel like I keep my home somewhat tidy, but seeing the amount of dust it picks up when I go to clean it is very eye-opening.

I love this air purifier! Not only do they all look great and modern, but the filter and technology is great! It works quickly to deodorize and clean the air of my apartment, and looks great while doing it!

Coway’s Airmega 150 is a stylish air purifier available in sage green, pink, and white. Love the auto feature, which is triggered by heightened allergens or dust in the air. I’ve noticed that after scooping my cats’ litter box, which is adjacent to the purifier, it automatically turns up the purification level to reduce the dust. Only con with this air purifier is the high cost of replacement filters. Otherwise, it’s perfect!

I have a few different styles/sizes of the AirMega in my home. Air quality in general is confusing because there are so many invisible factors involved (PM+dust, CO2, VOCs, etc), but what I can say for certain is that I've noticed a significant drop in airborne dust in my home. Issues with it are that the filter replacements are expensive and the app has become more and more inaccessible over time, to the point where I can't even use it anymore. I wish they'd add something simple like Matter/HomeKit support.

I've had two 'Mighty' air purifiers for the last 4-5 years, and they're great. I have the older/less feature-rich models, but they do the job well and it's easy to clean the pre-filter and replace the filters periodically. The auto feature is nice to have it determine how quickly to filter the air depending on air quality.
