Having been using thee filters for years, decades even. They help my allergies immensely. Today I was unable to install as the box was just a touch too big to slide into the furnace slot. Luckily I was able too bash the corner with a hammer slightly, and it slid it perfectly. 20x25 do it best, 51111539507 70-0714-1170-9
I would recommend this to a friend!
