Advanced ion-exchange removes the calcium and magnesium behind the Florida Keys’ hard, mineral-rich water—reducing scale, spots, and dry skin so every tap runs soft, conditioned water.
The System Itself
A high-capacity resin tank with a built-in brine cabinet, installed right where water enters your Stock Island home. It runs itself—the electronic valve tracks your real usage and regenerates on demand, so you’re not wasting salt and you’re not running out of soft water.
Key Features
Sized for a family home in Monroe County and engineered to stay out of your way: high grain capacity, a valve that regenerates on demand rather than on a clock, and a high-flow design that keeps your pressure where it should be—perfect for life in the Florida Keys.

How It Works
Hard water from the main supply enters the system and leaves as soft, conditioned water. The softener removes the hardness minerals—calcium and magnesium—common in the Florida Keys, helping prevent scale, spots, and dry skin while giving you soft, luxurious water throughout your home.
Why hard water is a Keys problem
Calcium and magnesium are dissolved rock—common in hard, mineral-rich Florida Keys water. They don’t filter out like sediment; they come out of solution as scale on anything warm or wet: the inside of your water heater, the shower glass, the dishwasher element, the faucet aerators. Ion exchange is the only method that actually takes them out of the water rather than just changing how they behave.
Sits on top of the tank, monitors usage, and regenerates automatically when the resin needs it.
Ion-exchange resin attracts and removes hardness minerals common in the Keys.
Holds salt for automatic regeneration, recharging the resin so you always have soft water.
Regenerates on demand—not on a clock.
Timer-based softeners regenerate whether you needed it or not—wasting salt and water on a quiet week, and running out mid-cycle on a busy one. This valve meters what your Stock Island home actually uses and recharges the resin at the right moment.
See & Feel the Difference in the Florida Keys
Softening is one of the few upgrades you notice right away. Showers feel better, glassware comes out clear, and that hard-water ring around faucets stops coming back—especially with the mineral-rich water common in the Keys.

Soap and shampoo lather properly in soft water, so you use noticeably less of both.
In the Florida Keys, hard, mineral-rich water can leave scale in plumbing and water-using appliances. The Mr. Pure Water Whole-House Water Softener uses advanced ion-exchange technology to remove calcium and magnesium before water reaches a single fixture. A high-capacity resin tank—up to 42,000 grains—does the work, while an electronic control valve meters how much water your household actually uses and regenerates on demand rather than on a timer. The built-in brine cabinet keeps the resin recharged, and a low-salt indicator tells you when to top it up. The result is soft, conditioned water at every tap: less scale in the water heater, fewer spots on glassware, less film on the shower door, and noticeably less soap and detergent to get the same clean—ideal for Stock Island and the Key West metro area.
