I have been dealing with Filterbuy for a few years. The service and quality is absolutely fantastic. I can't think of better people I have dealt with in business . Over the years the business has grown and the service and quality has not changed.

Too thick for summer

Restricted the air flow causing the AC to freeze up leading to a very hot night! Went back to the filters we used before and it’s working again.

Very poor quality control. Pleats
on May 29, 2026

Very poor quality control. Pleats are bunched together on the sides instead of being uniformly spaced.
