Filters fit like a glove after receiving custom size filters. They appear to be of good quality. Time will tell.

I have an odd size a/c filter and found these on Filterbuy. It was an easy choice and bought a 6 pack to last me a while.

Quality Furnace Filter

I was in need of a uniquely sized furnace filter in a new home that had not had a new filter in several months. These filters fit perfectly and did a great job cleaning the air.

Nice filters as far as I can tell. Just put my first in. They came in a sturdy box so they were in perfect shape. Cost per filter is low.
