Best-seller whole-home filtration plus UV protection for cleaner, better-tasting, safer water from every tap in Saint Augustine South.
The System Itself
A single filter housing plus a stainless UV chamber, installed where water enters your home. Compact for a garage wall or exterior run—no tank and no floor space taken up.
The UV Advantage
Media filters are excellent for 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 perform 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 to live on your main line.
A long-life lamp with a simple, scheduled replacement—easy for busy St. Johns County homeowners.

Final-Stage Protection
UV-C light helps neutralize bacteria, viruses, and other harmful microorganisms—without adding chemicals to your water.
In St. Johns County, water can travel miles through dark, damp lines before it reaches your home. In our humid, coastal climate, those conditions can support microorganisms and biofilm growth—so 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 in Saint Augustine South.

The upgrade is $500—and it covers what a filter can’t.
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 with hard municipal groundwater in St. Johns County, ask us which build is the better fit—the standard system carries a polyphosphate scale-control layer that the UV build does not.
