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!
