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.

Product was slightly too big and had to modified to fit in the opening, not a complete seal but at least got it to fit in my opening.
