NAPA lists their Gold filters as 99% @ 30 microns. I was hoping for something like the Carquest Premium 99% @ 20 microns. Does anyone know what the NAPA Gold is rated at 20 microns?

Now that the NAPA Golds are made by PGI, I would think the efficiency would be the 99% @ 20u. Quite possible that the NAPA website is old info for the NAPA Gold when it was being made by WIX/Mann+Hummel.
Should try to email NAPA support and ask if that efficiency info is old and out of date.
