Best-seller whole-home filtration plus UV protection for cleaner, better-tasting, safer water from every tap in Marathon, Florida.
The System Itself
The whole system is a single filter housing and a stainless UV chamber, plumbed in where water enters your home. Compact for a garage wall or exterior run—great for Marathon’s tropical, storm-prone climate.
The UV Advantage in the Keys
Media filters are great at particles and dissolved chemicals, but they don’t reliably handle living organisms. UV-C removes nothing from the water—it disrupts the DNA/RNA of microorganisms so they can’t reproduce. In the Florida Keys, running filtration first also helps UV work better, because clearer water lets the light reach everything.
A dedicated sterilization stage plumbed in after the filter—whole-home.
Nothing is added to your water—no chlorine, no aftertaste.
A corrosion-resistant chamber built for salty Florida Keys air.
A long-life lamp with a simple, scheduled replacement—easy for Keys homeowners.

Final-Stage Protection
UV-C light helps neutralize bacteria, viruses, and other harmful microorganisms—without adding chemicals to your Marathon water.
In Monroe County, water can travel miles through dark, damp water lines before it reaches your home. Those conditions can support microorganisms and biofilm growth—so whatever treatment happened at the plant isn’t always the whole story. UV-C sterilization at the point of entry adds a powerful final layer of protection to help inactivate harmful microbes throughout your home’s water supply.

The upgrade is $500—and it covers what a filter can’t in the Florida Keys.
A media filter is excellent at particles and dissolved chemicals, but it does not reliably deal with living organisms. UV-C does not remove anything from your water—it disrupts the DNA and RNA of bacteria, viruses, and protozoa so they cannot reproduce, using no chemicals at all. If you’re on a local well/cistern, have had a boil-water notice, or simply want that last layer covered in Marathon, that is what the extra $500 buys. With the Florida Keys’ moderate hardness, ask us which build is the better fit—the standard system includes a polyphosphate scale-control layer that the UV build does not.

The Mr. Pure Water Whole House Water Purification System with UV Sterilization combines advanced 3-layer filtration with powerful UV-C technology to deliver cleaner, better-tasting, and microbiologically safer water throughout your entire Marathon home. The outer polypropylene layer catches sand, dirt, silt, and rust flakes—helpful for Keys wells/cisterns and older lines—and protects what sits behind it. The middle gradient media handles a broad chemical and clarity range—chlorine, VOCs, dissolved solids, and microplastics. The inner activated carbon core does the final polish and takes on PFAS and industrial chemicals. Then a 304 stainless chamber with a UV-C lamp finishes the job on what filtration alone cannot reach, giving your family the ultimate in water quality, protection, and peace of mind in the Florida Keys.
