See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Fort Pierce South families.
The System Itself
Designed for Fort Pierce South kitchens: the whole system fits under your sink with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline between them. No bulky storage tank—water is purified on demand instead of sitting and waiting.
The first cartridge captures rust, dirt, sand, and larger particles—helpful for hard, groundwater-based supplies common in coastal St. Lucie County.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—great for Fort Pierce South water.
The heart of the system—rejects dissolved solids and heavy metals, sending the concentrate to the drain.
Final cartridge polishes the water and adds beneficial minerals back for a balanced pH—ideal for coastal St. Lucie County homes.
Filtration Stages
Each stage handles something the one before it left behind. UV is the fourth step in the sequence and the one stage that is not filtration at all - it is there to deal with what a filter cannot catch in Fort Pierce South water.
Removes rust, dirt, sand and large particles—great as a first step for Treasure Coast water.
Reduces chlorine, odors, color, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for hard St. Lucie County water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
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. It’s included in the price on every system we install in Fort Pierce South.

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 Fort Pierce South homes dealing with hard, groundwater-based supplies and scale buildup. 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.
