Best match for Orlando

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.

Orlando drinking water is withdrawn from the Lower Floridan aquifer and delivered by Orlando Utilities Commission. No OUC or City of Orlando residential softener ban like LACSD Measure S turned up. Ask the sewer agency on the bill before you cut a brine drain. This is not a legal opinion.
