The flow rating for the Wix filter 42096R 14x4" paper element is 600 CFM.

Wix filter 46944R which flows 1000cfm is virtually the same as 42096. They are both 14X4 paper filters

The two other differences are cost and filter thickness

46944R costs $28 and is 1.25 inches thick 1000CFM
42096R costs $13 and is 2.25 inches thick. I guess the thickness accounts for the flow rating
