The Coway Airmega 400S is a great choice if you want an air purifier that can clean a lot of air without making a lot of noise. This unit is not too expensive and is easy to use. It has a user interface on the unit itself and can also be used with an app.
The unit also has an air sensor that tells the “smart mode” how clean the air is so that the filter can be turned on or off. Most importantly, the filter is one of the best at cleaning the air, making it a good choice for people who are sensitive to airborne particles.
[content-egg-block template=offers_logo hide=price]You can get the Airmega 400 in white or graphite/silver. I tried out the model in graphite, which went well with the darker colors in my dining room. The unit is 23 inches high, 15 inches wide, and 15 inches deep. It takes up some space, but it doesn’t take over the room.

Where to get Coway Airmega 400 True HEPA Air Purifier?
With that kind of power, you can reach a lot of people. It feels best in a room no bigger than 1560 square feet, which is three times the size of the area that the Dyson TP04 Pure Cool Tower can cover. If you add more, its 400 CFM rating will start to go down. But what’s crazy is that the Alen Breathe Smart Classic Large Room Air Purifier only covers 1100 square feet but costs $100 more.
Some air purifiers have three stages of filtering, but the Coway Airmega 400 only has two, or more like two and a half. This sounds like it would be less effective, but in reality, it combines filters instead of splitting them up. Particles first hit pre-filters, and then the activated carbon green True HEPA filter Coway Airmega combined.
Even though a few air purifiers in this price range do a better job, the Coway Airmega 400 has more to offer than just performance. It’s still worth every penny, but the fact that it can be used with an app makes it even better. If you have Wi-Fi, the app will let you know when the HEPA air filters need to be changed. The Oransi Max HEPA Air Purifier is less expensive, but it only cleans air in half as much space.
