There are several tactics and devices that you can use in your home to improve air quality. If you are concerned with the air quality in your home or have family members with allergies or asthma, look into HEPA filters. Using HEPA filters in the home is one of the most effective ways to purify indoor air.

The Origins of HEPA Filters

HEPA filters were originally invented in the 1940s to protect workers in nuclear facilities from radioactive particles. They were so effective that hospitals began using them to prevent the spread of viruses and other applications.

What Makes HEPA Filters Superior

HEPA filters capture particles that are 0.3 microns or larger. They become trapped in a mat of randomly arranged fibers made from fiberglass. The particles stick to the mat and remove 99.7% of contaminants from the air that are bigger than 0.3 microns. When shopping for HEPA filters, make sure the label says “True-HEPA” instead of “HEPA-like”. Many manufacturers try to use the HEPA name without meeting the specifications.

Applications for HEPA Filters in the Home

There are three main ways that HEPA filters help inside of your home. HEPA filters can be used with vacuum cleaners, HVAC systems, and air purifiers. Because HEPA filters capture particulates better than standard air filters, they’ll get dirtier faster and will need to be replaced more often.

HEPA Vacuum Cleaners

Dust and other allergens on your floors and embedded in your carpets directly affect your indoor air quality. A HEPA vacuum is especially valuable for pet owners because it captures tiny dander particles without releasing them back into the room.


HVAC filters play an important role by filtering the air that circulates throughout the entire house. The quality and thickness of HVAC filters vary widely, and you’ll spend more on HEPA filters than the cheaper, standard types. Consider it an investment in your family’s health.

HEPA Air Purifiers

This year, the popularity of air purifiers has soared due to COVID-19. People are buying air purifiers for their homes and businesses to make the indoor environment safer and healthier. A HEPA air purifier can reduce the transmission of airborne viruses.
