Review on 🔍 Enhanced Filtration with FilterBuy 15X20X1 Pleated Furnace Filters for HVAC Systems by Mark Jefferson

I ordered a set of 15x20x1 MERV 11 "Gold” and received a rather mediocre quality. The folds of the filter material are distributed unevenly and the filter material itself does not have the same thickness/density. If you hold it up to the light, it's covered in spots where you can see straight through the filter, much like you'd expect from contractor filters. Compared to other more expensive brands I've bought from Revain in the past, I will stick with these other brands.
