What is Indoor Air Quality?

Indoor Air Quality (IAQ) refers to the air quality within and around buildings, especially as it relates to the health and of the building's occupants. Removing common pollutants indoors can help reduce your risk of indoor health concerns. Particles that can impact Indoor Air Quality include common smoke, bacteria, tobacco smoke, pollen, pet dander, and dust.

What is a HEPA Filter?

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).

Why are Medify Air Filters Special?

Medify filters use a three-layer system to catch and remove allergens, pet dander, and more; and are tested to remove 99.9% of particles down to 0.1 microns. The filters have an airtight seal, to reduce leakage of dirty air bypass the filter, and ALL Medify filters are HEPA H13.
