Best-seller whole-home filtration plus UV protection for cleaner, better-tasting, safer water from every tap in Key Largo.
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—ideal when space is tight in Key Largo. No tank and no floor space taken up.
The UV Advantage for the Keys
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 makes the UV work better, because clear water lets the light reach everything—helpful in Keys homes using storage tanks or treatment systems.
A dedicated sterilization stage plumbed in after the filter—ideal for Keys homes.
Nothing is added to your water—no chlorine, no aftertaste.
A corrosion-resistant chamber built for Key Largo’s salt air on your main line.
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 Key Largo water.
In the Florida Keys, water can travel a long way through dark, damp plumbing before it reaches your Key Largo home. Those conditions can support microorganisms and biofilm growth, which means whatever treatment happened upstream 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’re on a well, rely on a storage tank (common in the Florida Keys), have had a boil-water notice, or simply want that last layer covered, that is what the extra $500 buys. On hard water, ask us which build is the better fit for Key Largo—the standard system carries a polyphosphate scale-control layer that the UV build does not.
