What Is a HEPA Filter?

You already know you should be changing the air filter in your HVAC system each month. But do you know which air filter you should be choosing for your home and system? There are lots of different air filters on the market, and each one serves a different purpose.

Take for example, HEPA filters. HEPA, or high efficiency particulate air filters, are air filters that can remove a great volume of particles from the air. In fact, HEPA filters can remove particles can be as small as 0.3 microns (a human hair, by contrast, is 17 to 181 microns in diameter). Learn more about these particle-catching wonders here.

How HEPA Filters Work

HEPA filters work by forcing air through mesh layers that are made of fiberglass. These layers trap particles such as pollen, dust, smoke, pipes or cigars, pet dander and other allergens. Most air filters that are sold now are fitted with HEPA filters. They are easily found in big box stores and hardware stores.

Buying the Right Filter for Your Space

A “true” HEPA filter must pass a test before it can get the HEPA seal, which is why these filters tend to be a little more expensive than other filtration devices. However, because of the high quality performance levels these filters tout, the extra cost is worth it.

Before buying a HEPA filter for your home, it’s important to know how powerful the filter should be in order to clean the air. Considering every home is different, it’s best to contact an HVAC professional to be sure you’re choosing the right size filter for their homes.
