  • Cut chlorine 86%
  • Rated most durable build by WaterFilterGuru

Cons

  • Not NSF-listed

What to know about Filterbaby All-Metal Shower Filter Pro

An inline filter in a titanium-aluminum metal housing, with a pleated microfilter around activated carbon and a 3-month cartridge. It cut chlorine 86% and kept 94% of flow in WaterFilterGuru's test, which also gave it most durable build. It suits buyers who want to avoid plastic housings.
Editorial notes

Why it stands out

Why we like it

This is the choice for buyers who specifically want to avoid plastic. In WaterFilterGuru's test it cut chlorine by 86% and kept 94% of flow, at 1.63 gpm, and the tester called it the most durable build.

All of that comes from a single tester. The filter is not on NSF's 177 list.

What to know

Skip it if certification matters to you. It is uncertified, and Interior Medicine places Filterbaby in its lowest tier because the company shared no data.
