Trying to cancel subscription
on February 12, 2026

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!!!

We go from heat to nothing to air conditioning in a matter of days here, so I won't go without knowing the air is being filtered. FilterBuy is my favorite!

Wrong size
on December 20, 2025
Posted by: Anonymous
Two orders in a row now Filterbuy has screwed up the size on a custom order. The stickers on them are the right size, but when measured they are significantly larger. Same mistake both times. As a result they do not fit. This used to be a good company. They've lost their way the last 2 yrs. Try somewhere else.
