A carbon filter tank and a water softener working together at your main line: chlorine, chloramine and hardness out of every tap in the house.
If your water smells like a swimming pool and leaves white crust on the faucets, you are dealing with two different problems, and one tank can't fix both. That's why the whole-home system we install uses two. It goes in where the main water line enters your house, so every faucet, shower, washing machine and water heater gets treated water, not just the kitchen sink.
Tank one is catalytic carbon. MAWSS disinfects with chlorine and chlorine dioxide, and some city systems use chloramine, which regular activated carbon is slow to remove. Catalytic carbon handles both, so the chlorine smell and taste actually come out. Tank two is the water softener. It trades the calcium and magnesium behind scale buildup, spotty dishes and soap that won't lather for sodium, then rinses itself clean with salt from the brine tank that sits beside it.
A quick word on the name. Some companies use "dual tank water softener" for two softener tanks that take turns. Ours pairs a filter with a softener, so one system handles taste, odor and hardness together. The equipment is the Hydrotech HT89UF HTO, which Hydrotech lists as certified to NSF/ANSI 42, 44 and 372, with upflow regeneration and a digital control valve.
Hardness changes from one water source to the next and from well to well, so we don't guess. We start with a free in-home water test, size the tanks to your household and your numbers, and install it. The system is $4,995, backed by our 1-year parts and labor warranty, or a lifetime labor warranty when you add our $34.95/month maintenance plan.
City water here arrives with a chlorine residual (MAWSS reports up to 2 ppm and adds chlorine dioxide), some systems elsewhere use chloramine, which ordinary carbon is slow to remove, and hardness changes from one water source to the next and from well to well. One system handles both, and a free water test sets the size instead of a guess.

A softener removes hardness and a carbon filter removes chlorine taste. On Mobile's soft, chlorinated water the filter often matters more. How to tell.

Published tests put most water here in the USGS soft range: MAWSS reads 2.2 to 2.9 gpg. When a softener earns its place, and the number that decides it.
