Junk Catcher
on April 21, 2026

Live near the coast so the air quality would seem pretty good. Don't run the HVAC much but when I do, the filter catches a lot of junk I don't to breath. We change the filter regularly by subsription so we save money on gas and I don't have to keep a log. Easy way to breath cleaner air.

Not tire sizing
on April 20, 2026
Posted by: Customer
We bought different 3 sizes of filters, was very disappointed that I had to shim the filters to make them stay and tape the gap so unfiltered air didn’t leak by. We had always used 3M filters that were always very tight, we will not be ordering them again, the sad thing is that we bought a 6 months supply!
