Perfect custom sizes.

My Rheem apparently requires an oddball size filter. Filterbuy makes them precisely the custom size it needs, and they're made in the USA. This is my 3rd order over 3 years (I change them every 3 months), and they're perfect every time, right down to the millimeter.

Merv 11 is anazing

I bought the Merv 11 its amazing. No dust at all and its been 2 weeks. Unfortunately, I measured without slotting room for the metal door to close . Its a little too big. It did force it inside but for the money I should have been more careful. It needed to be 1/2 inch smaller

Perfect filer and awesome price! This was a one-time purchase but I'm planning on signing up for Auto refill for convenience and savings.
