Filters do not fit
on September 1, 2026
Posted by: Customer
You sent me 2 custom 16x25x1…they are too big, I CANNOT use.
The six I originally ordered I still have…they are 16x25x1 and are too small, but at least I can put a LOT of duck tape on the ends and make them stick uo there.
I am very unhappy with these filters. THIS is the 2nd request to have some contact me. I sent photo last time.
Thank you. .

I like the fact I can receive quantity of these filters without the hassel of going to buy a few @ a local store. They are great filters.

Filters are okay, don't love the packing

When buying filters in a bit of a larger quantity, it is way more preferable to have them individually wrapped. I store these in a crawl space near my furnace, and had to find alternative storage. The price isn't so much cheaper that it makes me think "oh, this is worth that extra step"

Size is definitely custom made to fit my unit. Quality amazing especially since I have 3 dogs and 2 cats . I get the whole year and I am worried free. It’s filter everything out. Everything comes quick in a box packaged carefully and never been damaged. I been ordering for years

Ordering online was a breeze. Filterbuy have every size filter. The prices are very good. I don’t have to drive around looking for the right size and good deals.
