First, when did Wix revise their efficiency numbers? The Product Detail that I saved in July is different than the current one.
These are about the best priced filters I can get around here. I was pretty comfortable moving to the Baldwins which I can get locally but after seeing the new numbers from Wix I guess I'm rethinking it....again.
51040 OLD
50% at 15 microns
95% at 31 microns
Nominal 21
51040 NEW
50% at 6 microns
95% at 20 microns
Nominal 21
B43-S
50% at 18
98.7% at 40 microns
Established Micron Rating? Same as nominal? 18
