The quality of the cardboard

The quality of the cardboard used to stabilize the filter is far above anything I have bought at the big box stores. . I used to be in the HVAC industry so believe me when I say the cost is very reasonable. I will definitely be a customer for life. Thanks for making such a quality product. .

So happy with these filters

My rental building gives me free filters but they were causing me to get lint all over my apartment. Im so happy I found Filterbuy. Better MERV than my old filters and no lint and dust all over everything. VERY happy!
