The System Itself

Capacity & Pricing
The systems treat water the same—the difference is how many gallons the media is rated to handle before replacement. Larger households and higher-use homes in Key Largo are often better served by the 800,000-gallon build.

How It Works in the Florida Keys
Water from municipal supply or a storage tank enters and leaves cleaner, passing through three stages along 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 Key Largo homeowners dislike about softened water.
First line of defense that reduces contaminants—helping protect Keys treatment systems and plumbing.
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.
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 feeling that turns some Key Largo households off traditional softeners.
Effectively Removes & Reduces
The pre-filter and media stages handle the everyday range of what comes down a supply line in the Keys—particles, chlorine and the chemistry behind bad taste, odor and color.
Reduction performance varies with source water and household usage. We test your water during your Key Largo visit so you know what you’re starting from.

Cleaner Water for Key Largo Living.
Salt-free conditioning gives you scale protection without the slick, hard-to-rinse feeling of softened water—great for Key Largo showers.
Helps cut the hard-water buildup that fogs shower doors and leaves rings around fixtures in Key Largo homes.
Filtration reduces chlorine, taste, and odor—so your Key Largo shower water is 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—ideal for Key Largo homes dealing with hard water and the Florida Keys’ limited freshwater supply. 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 with coastal humidity and salt air in Key Largo, reducing scale buildup can help protect plumbing and fixtures from extra wear. The media is rated for ten years or more of service.
