Need a replacement air filter?

There’s a lot of talk about actual vs nominal measurements for filters and we’re here to help clear up any questions you may have.

Actual measurement: The measurement you get when you measure the filter yourself (Usually will include ¾ and ½ sizes).

Nominal measurement: The measurement printed on the side of the filter (Rounded up to the nearest number).

Did you know: Filter measurements are usually rounded up to the nearest number?

While using a tape measure will give you the most accurate measurement of your filter, you will need to round up the numbers to match them with a filter size.

When in doubt order the nominal measurement if possible.
