The System Itself
The whole system is a single filter housing and a stainless UV chamber, plumbed in where the water enters your Duck Key home. Compact enough for a garage wall or an outside run - no tank, no floor space taken up.
The UV Advantage for Duck Key
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 (especially helpful with Duck Key municipal/desalinated water).
A dedicated sterilization stage plumbed in after the filter for Duck Key homes.
Nothing is added to your water—no chlorine, no aftertaste.
A corrosion-resistant chamber built to live on your main line in the Florida Keys.
A long-life lamp with simple, scheduled replacement for Duck Key.

Final-Stage Protection
UV-C light helps neutralize bacteria and viruses without adding chemicals to your Duck Key water.
Water may travel miles through dark, damp water lines and plumbing environments before it reaches your Duck Key home. Those 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 in the Florida Keys.

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. In Monroe County’s hard water, ask us which build is the better fit - the standard system carries a polyphosphate scale-control layer that the UV build does not.

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.
