Before you can begin changing your air filters, you have to find them first! Once you do, you can write done where each filter is located, along with the size and type of each. Also, keep in mind, some systems may have more than one filter!

Which Room Are Air Filters Located?

  • Look in the attic — the air handler may have a removable cover on it.
  • Check your basement.
  • Look behind the return of a mounted wall unit.

Vertical HVAC Systems:

Vertical HVAC systems are typically found in basements or crawl spaces where space is limited. If you have an up-flow vertical HVAC unit, the air filter will be located at the bottom of the system. If you have a down-flow HVAC system, the filter is most likely located at the top of the unit.

Horizontal HVAC Systems:

These units are found in attics, garages, or large basements. You can find the air filter positioned vertically in a slot on the side of the unit.
