Best-seller whole-home filtration plus UV protection for cleaner, better-tasting, safer water from every tap in Stock Island.
The System Itself
One compact filter housing plus a stainless UV chamber, installed where water enters your home—great for Stock Island garages or exterior runs. No tank, no floor space.
The UV Advantage
Media filters are excellent at particles and dissolved chemicals, but they do not reliably deal with living things. UV-C removes nothing from the water—it disrupts the DNA and RNA of microorganisms so they cannot reproduce. Running filtration first also helps UV work better, because clear water lets the light reach everything—especially important in the Florida Keys.
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 to live on your main line in the Keys.
A long-life lamp with a simple, scheduled replacement.

Final-Stage Protection
UV-C light helps neutralize bacteria, viruses, and other harmful microorganisms—no chemicals added to your Stock Island water.
In the Florida Keys, water can travel miles through dark, damp water lines before it reaches your home. Warm, humid conditions can support microorganisms and biofilm growth, which means whatever treatment happened at the plant is not 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 cannot.
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 are on a well, have had a boil-water notice, or simply want that last layer covered, that is what the extra $500 buys. And in the Florida Keys, hard, mineral-rich water can be a factor—ask us which build is the better fit. The standard system carries a polyphosphate scale-control layer that the UV build does not.
