My fault for not reading the specific measurements, the "4" isn't actually 4 inches. its like 3. 7 or something. Maybe I was born yesterday and this is normal for filter sizing, but it does not fit like the 20x20x4 Honeywell filter that my HVAC people put in when our furnace was replaced a few months ago.

These filters are outstanding I change it out once a month when I remove them they're black 18x18x 1. I bought this home as they were building it in 2021. thats when I moved from CA to FL I saw your ads and been using them ever since.

good filters

These furnace filters seem much better than the last ones we bought. The filters we bought previously had no reinforcement and the cardboard bent when I tried to slide it in place. These filters have 2 types of reinforcement in them and slide in place easily with no bending. We're very pleased with the product.
