Air filter Size and Installation
Filters are sized in two ways: nominal and actual. Nominal is the approximate size of the filter, rounded up to the nearest inch. Actual is the filter’s exact size.
In addition to standard height and width dimensions, air filters also vary by thickness. They can be less than one inch thick, or up to six inches thick.
The most popular air filter sizes are listed below, sorted by width x height x depth in inches.
Getting an exact fit is crucial to having an effective air filter - the wrong size won't fit and will cause the filter to stop working properly . To ensure you get the right fit, take your current air filter out and check the size printed on the frame.
- When inserting your air filter, make sure it fits snugly in the chamber. Loose filters may let air pass around the filter instead of through it.
- Make sure your filter is sturdy. The frame should be strong enough to withstand pressure caused by the air that moves through it. Check the frame after installation to see if it is intact and that the joints are secure.
