It's great that you can buy in bulk, and they get cheaper the more you purchase depending on your budget. I will probably buy again once I an done with the one's I have.

Sized small - Loose fit
on November 7, 2023
Posted by: Anonymous
Filters appear to be excellent quality, built well and are competitively priced. The only problem I had is they are about a 1/4" smaller (length & width) than the 3M and Honeywell filters I had been using. As a result they are a very loose fit in my ceiling mounted grilles and fall out as I am trying to close the grille door. Balancing on a ladder and trying to hold the filter in place while closing the grille door is a challenge. Once installed, the filters lay on the grille until suction lifts it up about a 1/4" to 1/2" and then the filter drops back down when the fan shuts off. After I using the 4 filters already purchased I'll have to make a decision whether to go back to 3M or not

we have used the same type of filters for a few years and have not had any issues at all. When they work; keep using the same filters.

Inferior substituted product size
on November 6, 2023

This was another repeat order of same filters-this time smaller filters were just taped together to make our size significantly reducing the usable filter area and causing undo stress/pressure on furnace and ductwork. Very poor quality substitution without our permission
