Nine stages is the most media Waterdrop packs into a whole house unit, and at $529.99 it tops that range. The argument for it over the $419.99 WHF3T-FG is breadth of media rather than any certified performance difference, since neither carries a published NSF/ANSI mark. That makes the extra $110 a judgement call on manufacturer claims alone, which is worth knowing before spending it. It is a point of entry system and needs plumbing into the main line.
