Carrier FILXXFNC0017 16x20x4 MERV 8 Replacement Furnace Filter - 2 Pack

My HVAC system requires a specific size filter. This was the only place I found that carried the correct size. When I ordered them the original delivery date was about 6 days out. They actually arrived in 3 days. I was extremely happy with the early delivery. This will be my go to place for future filter purchases.

As good in construction as the more expensive filters that I bought for years, and the Atomic Filter cost less also.

Fit perfect, didn't have to change anything or do anything different. It is now performing it's duty.

For me the actual size is more important for a better fit than the nominal size when I order.
