The nominal size is a shorthand number rounded to the nearest whole or half inch, while the actual size is an exact measurement that depicts the filter's precise dimensions. If your current air filter does not have a dimension listed on the frame, use a tape measure to find the actual size.

Changing your air filter is important for maintaining a healthy lifestyle, as breathing dirty air can put you at risk of developing asthma, allergies, and other respiratory ailments. We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. Our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system as long as you choose the proper size.
