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. With its Smart Mode, you don’t need to worry about it being left on high settings too long, costing you money and wearing down the filter.

It will automatically adjust its power level based on the pollution in the room. Although it’s a powerful, user-friendly device, Coway haven’t focused on function at the expense of form — the unit looks great and won’t cramp your style. Just opening the unit up and looking at the filters will be enough proof that this is something you need.

Air Recommended Air Purifiers

Our Pick Perfect for bedrooms, playrooms, and living rooms, the Coway Airmega AP-1512HH is one of the best-performing, most durable, and most economical purifiers we’ve tested.

Most Popular The Levoit Core 300 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.

Also Great With high end air cleaning performance and a whisper quiet fan, the Winix 5500-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.

Best of the Best If you have a large space you want to remove irritants from, We recommend the Airmega 400S. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them. The 400S is designed to accommodate large room sizes.
