We wanted a direct replacement for our Blue Honeywell ESPs. They're blue in the photo, but what you get is an aluminum (silver) post-filter that doesn't look electrostatic. It's denser than the aluminum pre-filter, but my wife claims she smells like aluminum when the fan is running. (Your sense of smell is way better than mine so I can't disagree) Anyway, I can't find the original blues online so I might get stuck with these. I hope they really work in terms of dust collection.
