30" filter was a 1/2" inch short
on September 17, 2025
Posted by: Winslow S.
I purchased a 24" x 1" and a 30" x 1" filter, both stating they were 8" tall; the 30" came in a full 1/2" short, at 7. 5, where as the 24 came in at a full 8". How do you account for that? Now there's a gap in the filter and debris can get in the fan; not good enough

Live in a Dust Bowl
on September 14, 2025
Posted by: Anonymous
[This review was collected as part of a promotion.] I live in the desert Southwest that sees frequent dust storms. In the Summer I turn my system fan on 24 hours a day. I change the filters every 6 to 8 weeks. I rarely have to dust because the system filters do such great job of filtering all the dust out of the inside house air. I know I can breathe freely inside.

Quality of the filters

Had to buy a new HVAC system that came with one of the filters so I bought 3 more. Wife has asthma and we believe the foliage helped her breathing. So, I bought 3 more.
