Power and Effectiveness
The Airmega 400S dual filter system, featuring a pre-filter and the MAX2 filter, removes up to 99.97% of allergen, molds and fine dust. It also removes up to 99% of volatile organic compounds.
Air pollutants as small as one micron in size can be removed. The unit is very powerful and can cover an area of up to 1,560 square feet, cleaning the air of a room that size every 30 minutes.
Noise
The amount of noise produced by this air purifier depends on the power setting you are using. On the lowest setting, the Airmega 400S is surprisingly quiet, and you probably won’t even hear it unless the room is otherwise completely silent. On the highest setting, it is louder but not intrusively so — it’s roughly as loud as a fairly large plug-in desk fan.
Modes
The Airmega 400S has three modes and will switch between these automatically as needed. On Auto mode, the unit will automatically adjust its speed based on the pollution level of the room in real-time. On Eco mode, the 400S will shut down its fan when it senses good air quality for 10 minutes.
It will turn back on if pollution is detected. On Sleep mode, the units light sensor will detect when the room is dark and automatically switch to a quiet setting so that you can sleep in peace.
Monitoring and Control
The main unit uses LED lights to continuously display the air quality of the room. There is also an indicator that tells you when to change the filter — so you don’t have to worry about forgetting!
The Airmega AP-2015E(G) 400S connects to your home Wi-Fi network, not Bluetooth, and once this is set up, you can access all of this monitoring information from the app, which also gives you information on outdoor air quality. You can switch between these modes manually, either from the unit’s touchscreen panel, the Mega app, or through Amazon Alexa.
Conclusion: Should I Buy the Airmega AP-2015E(G) 400S Air Purifier?
The Airmega AP-2015E(G) 400S is a high-end, powerful and efficient air purifier. It can clean huge spaces quickly, and its dual filter system is truly effective at removing airborne pollutants, so you’re left with clean air.
