Real-time Air Quality Monitoring
Airmega’s pollution sensor tells you the indoor air quality in real-time. The
brightly colored LED bar lets you know if your indoor air is fresh or unhealthy
every minute of the day. In addition, the particle sensor classies the particle
size of the PM10 and PM2.5, and the Bar display level of air quality.
Smart Mode
With Smart Mode, Airmega adapts to its surroundings. Fan speeds
automatically adjust based on the room’s air quality and room conditions.
Rapid mode
Rapid mode enables faster indoor purification.
The product operates at maximum performance until the air quality is
reduced to level 1.
EZ release
Coway’s unique front open type was applied to the product to remove and
insert a frequently cleaned pre-lter easily.
Max2 Filter
The Max2 lter (an activated carbon lter plus Green True HEPA lter)
reduces more than 99% of volatile organic compounds (VOCs), odors such
as NH3, CH3CHO, CH3COOH. It also captures and reduces up to 99.97 %
of airborne particles in the air such as pollen, pollution, and other allergens
Filter lifetime : Approximately 12 months(based on daily 8 hours usage at max speed)
Filter Lifetime Notications
With status alerts for Max2 filter & the Pre-filter, you’ll know when it’s time
to clean the Pre-filter regularly & replace the Max2 Filter. And because the
Airmega gauges how much air has travelled through it, you can be sure the
notifications are accurate.
