How On Time Air Filters Works

Step 1
Find Your
Filter Sizes

Standard sizes (what most homes need) are organized by thickness (1", 2" 4" and 6").

Whole house filters (usually 4 - 6") are sold by brand, as each brand's sizing is very specific.

Some systems require custom-sized filters. We've created a list of common custom sizes, but if you don't see yours listed, just let us know and we'll add it.

Homes with more than 1 filter will save 50% on every additional filter.*

How often do you like to replace your filters?

Experts recommend replacing filters every 3 months, but these factors may affect your decision:

  • Heavy or low A/C usage

  • Some whole-house filters require less frequent replacement*
