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.
