Our take

The Airmega 400 pulls air through both sides, so it needs two filters, and this set has both. Each Max2 filter combines a True HEPA layer with activated carbon.

Coway tracks filter life by use rather than time, and the purifier tells you when to change. The washable pre-filters are separate; rinse them, and replace them if they tear.

  • Airmega 400 and 400S owners

Questions about the Airmega 400 Max2 Filter Set

Do I need to replace both Airmega 400 filters?
Yes: the purifier draws air through both sides equally, so both filters load at the same rate. The set includes two.

How we judge. We haven't tested the Airmega 400 Max2 Filter Set in a lab of our own. The figures come from independent ratings (AHAM, Energy Star, NIOSH, the ASPCA) or the maker, and the verdict is ours, from those figures. No brand pays to be listed. Last checked Nov 7, 2026.
