Best match for Mobile

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.

Other options that still fit

  • Do not buy a softener on this supply

    This supply is soft on the published numbers. A salt tank is usually the wrong box unless you are on a well or a different utility. Test the tap before you buy hardness equipment.

    Shop water test kits

  • Under-sink reverse osmosis

    The under-sink RO we actually run is Cloud RO — NSF/ANSI 58, kitchen tap, not a whole-house tank. Check the exact listing if PFAS is why you are shopping. Shop Amazon first for under-sink RO, or buy Cloud direct. Waterdrop is a tankless option if you want that path. A certifier-listed pitcher is the cheap first step. Nobody is paying for a medical claim.

No district prohibition found in current research. Searched MAWSS and City of Mobile sewer pages and codes for a residential self-regenerating softener or brine-drain ban like LACSD Measure S. None turned up. Ask the sewer agency on the bill before you cut a brine drain.

Extra context besides the utility report and the chart above — geology, an unregulated table, or a published study. Not a second set of printed tap numbers.

Mobile drinking water is treated and delivered by the Mobile Area Water and Sewer System. No MAWSS or City of Mobile 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.

The 2025 Consumer Confidence Report prints hardness as CaCO3 49.6 ppm (range 38.3–49.6). We do not invent a second plant column.

Chlorine 2 ppm (range 0.29–2). Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
