Haven't need a new one yet.
I'm expecting the same quality as the expensive ones.

Too tight for my ac, which I didn’t know. They give no indication that you have to chose based on the ac unit in the description in the product page. I now k ow you have to go and dig for the link where it’s discussed.

I'm very pleased with the replacement filters for my HVAC system. I ordered the same ones last time and they do not disappoint. Also, they arrive MUCH sooner than expected. I saved more by ordering in bulk.
