Select Exact Dimensions:

Custom filters are made specifically for you and cannot be returned or exchanged – please measure carefully!
Unlike common nominally sized filters – custom filters are made to the exact measurement that you specify.
Each case of custom filters can take up to 5 business days to make and ship. Accelerated shipping options are not available.
1” custom filters will be ⅞” in thickness, 2” custom filters will be 1¾” in thickness, 4” custom filters will be 3¾” in thickness.
The manufacturing of extra large sizes may consist of more than one filter taped together.
