The Importance of Air Filters

Action Air recommends checking your air filter each month and replacing if needed.

But what kind of filter to use?

Several types of air filters are common in HVAC systems:

Importance of Changing Air Filters Regularly

  • Fiberglass filter. This throwaway air filter is the most common type. Layered fiberglass fibers are laid over each other to form the filter media and typically are reinforced with a metal grating that supports the fiberglass to prevent failure and collapse.

  • Polyester and pleated filters. These filters are similar to fiberglass filters but typically have a higher resistance to airflow and a superior dust-stopping ability.

  • High efficiency particulate arrestance (HEPA) filters. These units filter the air passing through them at a very fine scale.

Because filters are fairly simple, they essentially are porous membranes that allow air to flow through them.
