Creative Design
Smaller than its competitors, this lightweight smart air purifier was created to integrate into your home. It not only performs exceptionally well but doesn’t distract for its surroundings.
When looking at the outside skin of the unit, you’ll notice that the air vent holes become smaller the closer they get to the top. This pattern reflects that as air is pulled into the purifier through the sides, it’s cleaned as it moves upwards.
Instant Air Quality Monitoring
Unlike other air purifiers where you’re never quite sure if it’s really working, the Airmega 300 Smart Air Purifier provides you with instant feedback. Located on the front of the unit, the Air Quality Indicator constantly monitors indoor air pollution and gives you real-time information regarding its findings. Those findings are conveyed to you directly on the indicator in 1 of 4 easy-to-understand colors.
- Good (Blue)
- Moderate (Purple)
- Unhealthy (Pink)
- Very Unhealthy (Red)

Super Quiet Operation
