xOverview
The Medify Air MA-40 Genuine Replacement Filter is a authentic 3-in-1 cartridge designed to fit the MA-40 purifier. It combines a pre-filter, a True HEPA H13 layer, and activated carbon in a single unit, delivering a compact, easy-to-install solution that supports cleaner air in homes, schools, or offices.

Three-layer purification for everyday air
This filter relies on a three-stage approach to address a wide range of indoor air challenges.

This combination is designed to handle common indoor irritants such as dust, pollen, pet dander, and household smells.
