Filters were not same size

Filters were not same size as OEM.Both marked as 4 but youd was under 4 and OEM was slightly over 4. I modified the unit so I can use yours but will have to see how they work before I buy more. I bought a years supply so hopefully I can use them.

On time, and fits perfectly

The shipment was actually a day early! The filters fit perfectly, and have a place to write the instillation date, so I remember to change on schedule. Reasonable price as well. Quality looks excellent.

Poor replacement!

I had High hopes for these filters till I placed one in the furnace and discovered that its size did not match the size of the original filter. Both filters are called 20x20x4, the original is actually 19 15/16 x 19 3/4 x 4 3/8 inches, your filter is 19-3/8x19-3/8 x 3-5/8. So much smaller that it does not stay in the filter guides, I had to tape a piece of cardboard to the edge to get it to fit the furnace, very disappointed and will be sending the others back.
