Salt-based water softener

Two tall mineral tanks and a black brine tank of a salt-based water softener, plumbed with copper pipe in a garage.
Salt-based softener: two mineral tanks and a brine tank.

A salt-based softener is the thing that actually removes hardness. Size it from your grains and how much water you use, not bathroom count. It needs a drain.

Also for the kitchen

Under-sink reverse osmosis

Under-sink reverse osmosis system with a white storage tank, filter canisters, and colored tubing in a kitchen cabinet.
Under-sink reverse osmosis: filters, tank, and a second faucet.

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.

Other options that still fit

  • Salt-free conditioner

    A salt-free conditioner changes how scale sticks. It does not soften. Soap and spots stay closer to untreated. No brine line.

  • Whole-house catalytic carbon for chloramine

    Catalytic carbon with a chloramine claim (NSF/ANSI 42 for chloramine). Regular chlorine carbon is the wrong box.

  • Test the tap first

    A homeowner kit is a start. It is not a state-certified lab. Use a certified lab when the decision is expensive.
