Good Filter but lacks proper thickness

I normally buy 3M Filtrete 20x25x4 filters for my Honeywell HVAC units. They are actually 4 3/8 inches thick and the filters fit the plenum properly. The FilterBuy 20x25x4 filters are 3 3/4 inch thick and fit loosely in the plenum. I may have to have FilterBuy custom-make ones of the proper thickness in the future, or go back to the 3M Filtretes.

I heard about FilterBuy through their endorsement of the Dan Bongino show. When it HVAC guy recommended we upgrade our filters to a higher quality, they were the only place u looked.

I hate to admit it but I won't know if my filter is good or not until I change it in 6 months. But believe me, if it's not good I'll tell you.

Great Replacement Filter

The fit is great. Has only been installed for a couple of weeks and see a big difference in the amount of dust over the factory MERV 8 filter.

Product is good. Structure of filter box housing and contents could be more supportive. How well they filter the air wont be know until I change it out.
