Spec sheet says 4 microns. Is this the old OEM specification, or are these filters compliant with new OEM spec?

Interesting … Since the spec sheet refers to “Racor’s genuine high efficiency dual pleat media replacement” and that it’s “tested to OEM standards” one would assume it’s the new design. However, since the 4-micron spec is stated without reference to efficiency (or beta rating) it doesn’t tell us much… i.e. is it 99% efficient at 4 microns or 50%? It just says “ultra efficient”
