Whole-home scale prevention, filtration, and salt-free conditioning for cleaner water—ideal for Dry Tortugas living, with no salt brine to buy and no slippery-feeling water.
The System Itself
The whole system is a single treatment tank plumbed in where water enters your building. No brine cabinet to fill, no drain line to run, and nothing to plug in—great for Fort Jefferson’s managed on-site water. The media does the work and lasts 10+ years.
Capacity & Pricing
The systems treat water the same—the difference is how many gallons the media is rated to handle before replacement. For higher-use sites in the Dry Tortugas, the 800,000-gallon build can be a better fit.

How It Works on Garden Key
Your on-site potable water enters the system and leaves cleaner, passing through three stages on the way.
Conditioning, not ion exchange
A salt-based softener strips calcium and magnesium out of the water and replaces them with sodium. This system leaves the minerals in—it changes their form so they cannot stick. The result is scale protection without a brine tank, without a drain line, and without the slippery feel that some people dislike—especially nice for remote Fort Jefferson locations.
First line of defense that reduces contaminants before they reach the rest of your filtration system.
Converts dissolved minerals into microscopic crystals that stay suspended in the water rather than sticking to plumbing surfaces.
Imparts a negative charge to the crystals, reducing their attraction to pipes and surfaces—helpful where marine air speeds corrosion.
Soft-water benefits without the slippery feel
Because minerals stay in the water instead of being swapped for sodium, you get salt-free conditioning without the slick, hard-to-rinse feel—an easy win for Dry Tortugas homes and facilities.
Effectively Removes & Reduces
The pre-filter and media stages handle the everyday range of what comes down a supply line—particles, chlorine, and the chemistry behind bad taste, odor and color—important when water is managed on-site in the Dry Tortugas.
Reduction performance varies with source water and household usage. We test your water on the visit so you know what you’re starting from—especially important in Fort Jefferson where potable water is limited and managed on-site.

Cleaner Water for Fort Jefferson Living.
Salt-free conditioning gives you scale protection without the slick, hard-to-rinse feeling—great for tropical maritime Fort Jefferson living.
Helps reduce buildup that fogs shower doors and leaves a ring around fixtures—great for island living near the sea.
Filtration reduces chlorine, taste, and odor—so your showers feel cleaner, too.
The Mr. Pure Water Salt-Free Water Softener combines whole-house filtration with salt-free scale prevention in a single tank on your main line—an ideal fit for Fort Jefferson’s remote Dry Tortugas setting where potable water is limited and managed on-site. City or well water meets a triple purpose pre-filter that catches soil, rust, sediment, silt and sand before they reach anything else. A catalytic media bed then converts the dissolved hardness minerals into microscopic crystals that stay suspended in the water instead of plating out on your pipes, and a final conditioning stage imparts a negative charge so those crystals are no longer drawn to plumbing surfaces. Along the way the media reduces chlorine, VOCs, chemicals and the compounds behind bad taste, odor and color. There is no salt brine to buy, no drain line, no external power and no drop in pressure—and fewer hassles for locations like Garden Key and Loggerhead Key where marine exposure can accelerate wear on plumbing and equipment. The media is rated for ten years or more of service.
