Wrench 1 - I see your point but that is not an 'anti-ice filter', it is an airframe fuel filter which removes all sorts of particles including ice -pedantry I know but most airframe fuel filters do the same thing.
True. But those filters are marketed, requested, and installed more for their "anti-ice" capabilities vs other contaminates. Semantics for sure, but when contracts list those filters under cold weather equipment requirements you can appreciate how they get grouped under that heading in all discussions.
