Please Note: Due material limitations used to build a custom filter, we construct a double filter (two filters fused together) when any filter dimension is larger than 24.75” on both sides and or larger than 29.75” on one side. Please allow up to an additional five (5) business days for processing your custom filter order.
Custom filters are not eligible for return or refund.
How to Measure Your Filter
Steps 1 & 2
Measuring Length and Width (L x W). (If your filter is not a square, the smallest measurement goes first).
Measure the thickness (Depth) of your filter from front to back.
