iSpring WGB32BM review
iSpring WGB32BM 3-Stage Whole House Water Filter for Iron and Manganese
By Tom Calder
For well water with orange staining: the third cartridge targets iron up to 3.0 ppm and manganese up to 1.0 ppm, iSpring says. Above those levels you need a dedicated iron system. It does nothing for germs, so test a private well and follow CDC's advice on disinfection.
- Best for
- Well water with modest iron staining
- Skip it if
- Your well tests above 3 ppm iron
