They were very badly made. Most of them was squished waste of money.

Filters appear to be good quality. Packaging could use a little help. I suggest corner protectors in the box. The filters are useable but a bit crumpled on the corners.

Perfect Fit

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.

Well Made, good price
on June 25, 2026

These are very well made and much more affordable than what is sold at the local retailer. I like that I can put these on a subscription that suits my needs. I have always rented and remembering to change the filters has always been a chore. I want my new home's a/c to work well, timely filter replacement is important for that and this makes it easier to do so.
