Great service and product!

I always hated buying furnace filters. Box stores were always expensive, if they had them in stock. Filterbuy is a very decent price for buying a years worth a time. I change my furnace filter monthly due to have a smaller filter and also with pets. The shipment is always very quick and comes well packaged. Highly recommend Filterbuy!

FILTERBUY: 20x25x1 MERV 8 Pleated Air Filter
on August 20, 2026
Posted by: Customer
Thinner than quality filters (supposed to be 1", but it is not). Does not provide a proper seal. Air can leak around border
Also, cardboard not as sturdy/thick as my usual brand.

It may seem overboard to describe air filters as "Simply Fantastic", but those two words accurately sum up my experience as a FilterBuy customer.

Looks like a quality control

Looks like a quality control issue. Filter was 3/4 of an inch small on all sides. Did not match size printed on filter and did not fit my opening.
