Great Filters
on May 19, 2026
Posted by: Customer
I've been using FilterBuy for years and I order four sets annually. The price is reasonable and love the automatic ordering so my filters arrive just in time for the next change which I do every three months.

Not as snug as the OEM filter
on May 13, 2026
Posted by: Customer
This filter was about 1/4 inch shorter than the filter that came with the HVAC unit. I needed to pad the underside with strips of with cardboard, so that it would fit snugly up to the top of the slot, since air travels across the top.

I’m so happy I discovered Filterbuy. It is so convenient to have them come directly to your door when needed. It makes it easy to repair some on schedule. The filters are really nice quality.

I was able to purchase three filters that I usually get. I have always found this filter to be great.

Filters work well

Overhead ducts stay relatively clean now that we are using Merv11 filters. The automatic shipments work well, no 2nd guessing or forgetting to order them.
