I am bummed and disappointed, but, I can't say that I am surprised. Read this conversation all the way to the end. I really pressed this technical support person. I asked them to double confirm 98% at 20-30 microns per ISO 4548-12.
My guess is that the filters that do still have the metal backed media are actually 99%= at 20 micron and that all new "premium" Fram filters are being built to with different materials and will be 98% at 20-30 microns per ISO 4548-12.
You can see in the conversation below that at 4:45pm we were signing off ... and that's when I asked if he is 100% certain about 98% at 20-30 microns per ISO 4548-12.
I definitely invite other BITOG members to contact Fram to see if you receive the same information.
