HEPA air filters, also known as high-efficiency particulate absorbing filters or high-efficiency particulate traps, can remove at least 99.97% of airborne allergens and contaminants – including mold spores and dust as small as 0.3 microns.
HEPA filters are used in applications where contamination control is required, such as hard disk drives, medical equipment, semiconductors, nuclear power, the manufacture of food, and pharmaceutical products, as well as in hospitals, homes, and vehicles. HEPA filters in homes are often used in stand-alone whole-house air filtration systems. This equipment is placed in your ductwork and operates in partnership with your HVAC system.
The great thing about HEPA filters is that they effectively clean the air. The design of these filters makes them ideal for trapping more significant pollutants such as pet dander and pollen. These filters are also relatively cost-effective and only need to be replaced every few years.
