Interesting Facts About HEPA Filters

HEPA (high-efficiency particulate air) filters lead the way when it comes to air purification. The MERV (minimum efficiency reporting value) rating, which measures HVAC filter efficiency, ranges from 1 to 16, and HEPA filters go beyond MERV 16.

Are HEPA air filters the best? If they’re the most efficient, why don’t all homes use them? To answer your biggest questions about HEPA filters, let us first share some interesting facts about these wonderful filters below.

They Were Initially Used in Nuclear Facilities

Before they were used in residential settings, HEPA filters were originally designed in the ’40s to be used for nuclear facilities. They were tasked with removing over 99% of radiated air pollutants 0.3 microns and larger.

Two decades later, hospitals began using HEPA filters in hopes of curbing the spread of airborne germs and particulates. Today, these air filters are considered the gold standard in medical settings.

Your house doesn’t have to be as polluted as a nuclear plant or as contaminated as a health clinic to benefit from a HEPA filter. It’s actually a sound choice to improve your indoor air quality if you live with furry pets.

They Can Give Allergy Sufferers Some Relief

Anyone sensitive to pollen, mold, dust and other airborne allergens can experience less frequent allergy attacks with the use of a HEPA filter. It may not be able to block bacteria and viruses, but it’s good enough to trap a long list of air contaminants.
