Due to supply chain issues, some filter deliveries may take longer than normal. We apologize for the inconvenience.

Custom-Sized Air Filter Policy

Custom filters are made specifically for you and cannot be returned - please measure carefully!
Unlike stock sizes - custom filters are made to the exact measurement that you specify.
1" custom filters will be 3/4" in thickness, 2" custom filters will be 1 3/4" in thickness, 4" custom filters will be 3 3/4" in thickness.
Custom-sized air filters are built to tolerances of +/- 1/8".
The manufacturing of extra-large sizes may consist of more than one filter taped together.
