See the purity, trust the technology. A tankless under-sink system delivering ultra-clean, refreshing water on demand—perfect for Island Walk families in Collier County.
The System Itself
Designed for Island Walk homes, the system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. With no bulky storage tank, water is purified on demand—so it’s not sitting and waiting.
The first cartridge catches rust, dirt, and sand—helpful with Southwest Florida’s mineral-heavy water before it reaches the next stages.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—ideal for Island Walk water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain (helpful with hard SWFL water).
Final cartridge that polishes the water and adds beneficial minerals back for balanced pH—great for Island Walk kitchens.
Filtration Stages
Each stage handles something the one before it left behind. Here in Southwest Florida—where hard water and mineral scale can be a concern—UV is the fourth step and the one stage that is not filtration at all; it handles what filters cannot catch.
Removes rust, dirt, sand and large particles—common with hard Southwest Florida water.
Reduces chlorine, odors, color, and chemicals in Island Walk tap water.

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 Island Walk homes in humid Southwest Florida. 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.
