The quality was great! The performance is comparable with more expensive filters. The HVAC system hasnt missed a beat. I will order them again! It did take 2 weeks to get the filters, so plan ahead.

Took the smoke out of our home from CA & OR wildfires after taping the filter to the back of a fan. Took about 4 hrs for 2 story 4100 sq ft home and could breathe again. Thanks for a great product!

The 18x18x1 filter fit great. It's a size we weren't able to find good options for locally. The filter was high quality at a great value. Will definitely buy again.

This merv 13 filter is of better quality than the Filtrete that I have been using. It has eliminated the dust particles that my old one missed.
