See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Pelican Marsh families in hot, humid Southwest Florida.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, and a UV chamber sits inline between them. There’s no bulky storage tank, so you get purified water on demand—ideal for Pelican Marsh kitchens.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that reduces chlorine, odors, colors and chemicals ahead of the membrane—great for Naples-area municipal water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain (helpful with hard Southwest Florida water).
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in Pelican Marsh.
Filtration Stages
Each stage handles what the one before it left behind—ideal for hard municipal water common around Pelican Marsh and the Naples area. UV is the fourth step and the one stage that isn’t filtration at all; it’s there to deal with what a filter cannot catch.
Removes rust, dirt, sand, and large particles common in hard-water areas.

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 Pelican Marsh homes in the Naples area. 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.
