Based on maker documents and certification records. We haven't tested these filters ourselves.

Common questions
Does a whole-house filter remove PFAS?
Look for an NSF/ANSI 53 or 58 PFAS listing for the exact model. SpringWell claims PFAS removal; we found no listing for it.
Do I need a filter and a softener?
They do different jobs. A filter targets chlorine and taste; a softener removes hardness. Many city homes with hard water use both.
