Lasts longer

lasts longer than other filters. bought them specifically for dirt and sand as we live in the AZ desert and we get hit every year with sandstorms from the Cali sand dunes. Helps the pets with the seasonal allergies too. Grateful I do not have to climb the ladder a 12 times (x3) a year to change 3 filters out. Bought them for our shop too in 20x20s. Have to change 2 of them out there. I bought them for shop exhaust fumes and again dirt and sand.

These filters last longer than regular filters. I specifically bought them as we live in the desert and during monsoon season we get hit with sand from the Cali sand dunes. Helps the pets with their seasonal allergies too.

Actual dimensions of the filters
on July 21, 2025
Posted by: Eric R.
Actual dimensions of the filters received were smaller than 16x20x4 and did not fit snuggly in the filter compartment.
