Quality Filters

These things look better than I was expecting and the materials seem to be a bit sturdier than other filters that I've bought.

Trying to cancel subscription

I've been trying to cancel this subscription for a while because I simply have too many filters! Unfortunately, cancelling is not as easy as signing-up. Sure, they are good filters, but be sure you have room to store extras!

Effective filters

I change the furnace filter once a month and you can see what gets caught. Without filter changes the heat exchanger and AC coil would get coated with dirt.

Filters are good quality MADE IN USA

I have been using these filters for a while & another filter company were sending promos for their filters. So I did some more research into Filterbuy as a company. There are 2 reasons I went with Filterbuy, MADE IN USA & they produce filters in Pittsburgh PA. I live in Pittsburgh so you have to support local!!!
