What Is a HEPA Air Filter?

The HEPA air filter works on the principle of air exchange. Designed to block up to 99.97 percent of all airborne particulates, a properly rated, true HEPA air filter is efficient to capture particles as small as 0.3-microns. In Florida today, we see them used in vacuum cleaners, air purifiers, humidifiers and, you guessed it, HVAC systems.

The Humble Beginnings of the HEPA Air Filter

Just like duct tape, GPS and Super Glue, the high-efficiency particulate arrestance (HEPA) filter got its unceremonious start in the U.S. military. Originating with the Manhattan Project, the rationale for the HEPA filter borrowed from World War II-era military gas mask canisters. The same paper used in these filters largely remains the same to this day.

Hidden Dangers In Your Home

While you may not be seeking to trap radioactive particles in your home, HEPA air filters are instrumental in trapping pollutant particles that otherwise exacerbate allergies and asthma. It’s not just all the natural and man-made irritants found in the air; the comforts of home such as drapes, bedding and carpeting do a lot to keep many of these elements inside the home polluting the indoor air quality far worse than what exists outdoors.

HEPA Filters Contribute to a Healthy Home

Your indoor air quality management is enhanced when you use HEPA air filters. Aside from capturing dust and pollen, they can reduce bacteria and viruses, help to eliminate mold and mildew spores, pet dander, dust and dust mites, passive tobacco smoke and pet dander.
