  Reduced airflow in your Medify Air Air Cleaner can be due to a couple of reasons. First, the back grille may be blocked, so make sure side intakes or the front outflow area are not obstructed. Second, the filter may need replacing, so try replacing the filter.

The Medify Air MA-50 is an air purifier designed to improve indoor air quality by removing airborne particles, odors, and gases. It utilizes a multi-stage filtration system, including a True HEPA H13 filter, a carbon odor filter, and a pre-filter.

Function Description:

The primary function of the MA-50 is air purification. It draws in air, passes it through its filtration system, and releases cleaner air back into the room. The True HEPA H13 filter is capable of removing up to 99.9% of airborne particles as small as 0.1 microns, which includes common allergens, pollen, dust, germs, pet dander, mold spores, and smoke. The carbon odor filter, with its substantial carbon pellets, is designed to reduce household odors, volatile organic compounds (VOCs), and gases like formaldehyde, as verified by independent laboratory testing. A pre-filter is also included to capture larger particles such as hair and dust, extending the life of the other filters.
