iSpring WGB32B-PF review
iSpring WGB32B-PF 3-Stage Whole House Water Filter with PFAS Cartridge
By Tom Calder
A whole-house cartridge set with a carbon fiber stage iSpring says is SGS-tested for up to 99% PFOA and PFOS. That's a lab test, not a certification: it isn't listed by NSF, WQA or IAPMO. For drinking water, a pitcher or RO system certified for PFAS covers the water you actually drink.

- A PFAS-focused cartridge, if lab testing is enough for you
- Skip it if
- You want certified PFAS reduction
