See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Isles of Capri’s coastal conditions.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, with a UV chamber inline between them. There’s no bulky storage tank, so water is purified on demand—ideal for Isles of Capri’s humid, coastal homes.
First cartridge captures rust, dirt, and sand—helpful in coastal plumbing exposed to salt air and corrosion.
Carbon block media that reduces chlorine, odors, colors, and chemicals—helpful with coastal water concerns in Isles of Capri.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for hard water in Collier County.
Filtration Stages
Each stage handles what the one before it leaves behind—helpful for Isles of Capri’s hard water and coastal conditions. UV is the fourth step and the one stage that is not filtration at all—it’s there to deal with what a filter cannot catch.

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—ideal for Isles of Capri homes where salt air and hard-water scale can be tough on plumbing. 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.
