Stops dust at the filter and with pleats greatly increasing surface area filter can be used longer before needing a new one. Doing a great job.

DO NOT BUY!

Huge gaps between filter and frame so particulate can completely bypass the filter. This makes them completely useless. Pay a little more and buy elsewhere!

A Perfect Fit
on January 6, 2023

The return air filter opening was custom made by the heat pump contractor in a size that is not standard. The previous owner was using a flexible fiberglass filter cut from a roll. I wanted better filtration with a high Merv rating. Filterbuy fabricated a custom size for me and I love how the air quality has improved. The company is well organized and my filter ships the same day. I highly recommend Filterbuy.
