Medify MA-40

Who Is Medify?

Medify has become a household name in air purifiers and air purification products. An air purifier is a motor and a fan that draws the air in the room into the unit and forces air through the filter or filters, removing contaminants. The purified air is then returned to the room, and the cycle continues over and over again to continuously improve the air quality. What sets Medify purifiers apart is the advanced H13 True HEPA filtration which traps more dust, pollen, pet dander, smoke, bacteria & viruses than leading competitors, and can help dehumidify rooms. A poor-quality filter allows air to blow through a fan faster, so a company can claim to cover more square footage. They are not really giving you the performance you need and deserve.


HEPA is a type of pleated mechanical air filter. It is an acronym for "high-efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm) (*Source:
