These are extremely low quality noisy filter. You will hear hissing and whining which doesnt happen with a higher quality filter. I am returning them all.

Not the quality I expected from a MERV 13. I have bought elsewhere same rating and 10 times the amount of pleats with much much higher quality. And the fit on this is smaller than the vent for the size that I bought in other brands the other brands filled the hole precisely as they should. This brand left gaps all the way around the intake. . very disappointed in this product

Love it. I have asthma and live next to very heavy traveled railroad tracks and i could not believe the difference a top notch filter made. Will definitely purchase these from now on.

Merv 13 Pleated air Filter
on September 20, 2025
Posted by: Anonymous
Have been using this product for 2 plus years. Upon upgrading to the Merv 13 filtration, I noticed some dustballs collecting on the filters after first couple of filter changes. Now, no dustballs. These filters use "nominal" sizing. I had to add shims to filter box in order to prevent air bypass. I use the 4" deep filters and change every 4 months. I'm very satisfied with performance of these filters and will continue to use.
