An air purifier is a device that removes airborne contaminants in a room to improve 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 99.9% (H13 HEPA filter removes 99.9% and our HEPA H14 filter removes 99.99%) of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). *Source: epa.gov, What is a HEPA filter?

How does it work?

An air purifier is essentially a motor with a fan that draws polluted air in a room into the unit and forces that air through different layers of filter. The purified air is then returned to the room repeating this cycle over and over to effectively improve the air quality.

Why are Medify Air filters special?

We, at Medify, use a three-layer system to catch and remove allergens, pet dander, and more; and are tested to remove 99.9% (Our H13 HEPA filter removes 99.9% and our HEPA H14 filter removes 99.99%) of particles down to 0.1 microns. We make sure our filters have an airtight seal to reduce leakage of dirty air bypassing the filter. Our filters include H14 and H13 options, ensuring high performance and air quality.
