Usually we have no issues with these filters. They worked great in our HVAC system for years. Now with that said my last orders the filters are running smaller. There is a major Gap in with on all sides, I can hear my AC is whistling and I can slide my finger in between the framing, very disappointing. I am afraid to order these again. What’s going on? As you can see I have placed a folded newspaper on top edge and size edge to help it fit and not flop around while the fan is blowing. Hope this doesn’t harm my system. Not have the funds to purchase new ones at this time. My last order was 2 Box purchase a total of 4 filters.
