Under-sink carbon filters
An under-sink carbon filter treats the kitchen cold-water line. Typical job is chlorine taste and some organic contaminants. Lead only when a named listing says so.
It does not soften the house. It does not address arsenic or nitrate unless a certification row names those claims.
