See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Hutchinson Island South’s coastal lifestyle.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the filtration stages, with a UV chamber inline. No bulky storage tank—water is purified on demand, ideal for Hutchinson Island South’s humid, coastal homes.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with coastal conditions near the Indian River Lagoon.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for St. Lucie County tap water.
The heart of the system, rejecting dissolved solids and heavy metals—helpful for hard water common in our area—and sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in Hutchinson Island South.
Filtration Stages
Each stage handles what the one before it left behind—helpful for hard water and coastal conditions around the Indian River Lagoon. UV is the fourth step in the sequence and the one stage that is not filtration at all; it deals with what a filter cannot catch.
Removes rust, dirt, sand, and large particles—helpful with coastal grit and scale.
Reduces chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals and more—great for hard water and coastal conditions.

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—perfect for Hutchinson Island South’s coastal, humid conditions where hard water scale and salt-air corrosion are common. 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.
