Best match for Toledo

Whole-house carbon for chlorine

A single black whole-house carbon tank with a control head, installed in a garage and connected to copper pipe.
Whole-house carbon tank. No brine tank.

That is chlorine. A whole-house carbon filter with an NSF/ANSI 42 chlorine claim is the usual match. A softener will not take chlorine out.
