I was filtering our IPA with "3 micron" perlite on my pressure leaf (aka DE) filter and could have sworn I could smell hops more in the unfiltered product. Last I checked, hop aromatics were to small to be filtered away -- am I wrong?
P.S. I usually mix some PVPP into the precoat -- could that be a factor?
