The Airmega 400S's fans are notably powerful. They're capable of easily pushing the air of a 700 square feet room up to four times in an hour. Its CADR rating is 350, an impressive result considering that most purifiers score 200-250, which is quantifiable proof of its effectiveness in cleaning large spaces and guaranteeing good air quality, even if the air is very contaminated.

The 400S changes has 3 modes that adjust automatically depending on its sensor's readings. The Auto mode automatically adjusts the air filtration speed based on the air quality readings, while the Eco mode turns off the purifier when the air quality remains good for 10 minutes and turns it back on if it senses contamination. The Sleep mode detects ambient light levels and, once it gets dark, it will run the purifier at the lowest speeds possible, to keep the noise level as low as possible. See More
You can schedule the unit to run only on specified days and certain hours. With this option, you can eliminate useless running and save both energy and filter life. It's also useful for light sleepers, as the unit can be set to turn on automatically on low speed in the middle of the night when your sleep is at its deepest. See More
Instead of the numerous LCD status lights found in other purifiers, this unit has an LCD screen that shows real-time data regarding the operation of the purifier. The screen gives you info about the current airflow, power level, and filter status, among other useful stuff. This screen is easier to understand and more precise than indicator lights. See More
