See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Marathon Shores family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, and a UV chamber sits inline. No bulky storage tank—purified on demand, ideal for humid, hurricane-prone Marathon Shores.
First cartridge traps rust, dirt, and sand—great for Florida Keys Aqueduct water and post-storm plumbing debris.
Carbon block media that reduces chlorine, odors, colors and chemicals—great for Florida Keys Aqueduct water.
The heart of the system, rejecting dissolved solids and heavy metals—helpful with hard water common in the Florida Keys.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Keys drinking water.
Filtration Stages
Each stage handles what the one before it left behind—ideal for Florida Keys homes on aqueduct-supplied water. UV is the fourth step in the sequence and the one stage that is not filtration at all; it’s there to deal with what a filter cannot catch.
Removes rust, dirt, sand and large particles—especially helpful after Keys storms.
Reduces chlorine, odors, colors and chemicals in Marathon Shores tap water.
Removes up to 99% of dissolved solids, heavy metals and more—ideal for hard Keys water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for everyday drinking in the Florida Keys.
Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are the four filtration stages; step 4 is the built-in UV lamp for disinfection—extra peace of mind in hurricane-prone Marathon Shores, and included in the price on every system we install.

The Mr. Pure Water Under-Sink Reverse Osmosis System with UV Sterilization is a tankless point-of-use system that fits neatly under your sink with quick-connect fittings—great for Marathon Shores homes in the Florida Keys. Cold water enters a PP sediment cartridge that catches rust, dirt, sand and large particles, then a CTO carbon block that takes out chlorine, odors, colors and chemicals. The reverse osmosis membrane removes up to 99% of dissolved solids and heavy metals, sending the concentrate to the drain at a 1.5:1 pure-to-drain ratio. A built-in UV lamp then kills 99.99% of bacteria, viruses and microorganisms - the one thing a filter cannot catch - operating automatically on water flow pressure. An alkaline and mineral stage finishes the water, putting beneficial minerals back for a balanced pH. Five stages in all - PP, CTO, RO, UV and alkaline - producing up to 400 gallons a day on demand, with no bulky storage tank to hold water, take up space or invite secondary contamination.
Purified water makes clearer, better-tasting ice for every drink you pour in the Florida Keys heat.
A full cartridge set is about 8,000 bottles of water—clean water straight from your Marathon Shores tap.
Ultra-pure water with UV protection—peace of mind for hurricane-prone Marathon Shores.

The tankless build is compact, so you keep the cabinet space a storage tank would take—perfect for many Marathon Shores kitchens.
Four twist cartridges that swap out in seconds, with no tools and no mess.
