Have been using these filters for the last five years. They are great. I use two MERV 13 20x20x3 filters in my system and they last around 9 months between change outs. I use a manometer to measure pressure drop across the filter to tell me when I need to install a new set of filters.

Fits perfectly. I like the 3” thickness.
