23 x 20 x 1 pleated filters in the the exact size of 23 x 20 x 1. Finding the perfect fit filter isn't always easy so we teamed up with AAF Flanders to offer high quality exact fit HVAC filters with a MERV 8 rating. This filter will be made to the exact dimensions of 23 x 20 x 1.
Important note: The "exact" 23 x 20 x 1 filters are custom made after an order is placed. The manufacturers label will display the smaller dimension first (20 x 23 x 1). If you are replacing an existing 23 x 20 x 1 filter that was not purchased from us please measure your existing filter prior to ordering as its actual size is likely smaller. Please review our return policy on custom/exact size filters.
