Filterbaby All-Metal Shower Filter Pro

Pros

  • Metal housing instead of plastic
  • Kept 94% of flow in testing
  • Cut chlorine 86%
  • Rated most durable build by WaterFilterGuru

Cons

  • Not NSF-listed
  • Inconsistent THM results; totals rose in one test
  • 3-month cartridges, with running cost higher than the leaders
  • Large unit that hangs low; restrictive return terms

A niche pick for the metal-housing and pressure-focused. The evidence is thin, so buy it knowing it isn't certified.
