Perfect Fit
on June 27, 2026
Posted by: Customer
Replacing the Filtrete we have been using because these are a much EASIER fit. We have ceiling vents. These fit without having to force them in over the screws. We are seniors. Not safe on a stool/ladder having to force them in.

Pleated air filter dimensions
on June 25, 2026
Posted by: Customer
Outside dimensions are smaller than most all other filters I've used. The filters have a loose fit in the filter housing. Since all 5 of my filters are in the ceilings, the filters drop down after the blowers shuts off. That's OK with me, but the filters snap back up each time the blower starts, resulting in an objectionable snap. I will be going back to my big box store's filters even though they are more expensive.

Hopefully Will Fit

We bought these to replace the Filtrate filters. We have typical Florida ceiling vents. The Filtrate are VERY hard to insert. Read these are “smaller” and much easier to insert. We are seniors and do not feel safe climbing up, having to force the Filtrate in. We will begin using the Filterbuy next time we change them in a few months.
