See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Leisure City families dealing with South Florida’s hard water and scale buildup.
The System Itself
The whole 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. No bulky storage tank—purified on demand for Leisure City homes in hot, humid South Florida.
The first cartridge—catching rust, dirt, sand, and large particles before anything downstream sees them.
Carbon block media that reduces chlorine, odors, colors and chemicals—great for Miami-Dade municipal water ahead of the membrane.
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.
Filtration Stages
Each stage handles what the one before it leaves behind—helpful with Miami-Dade’s hard water. UV is the fourth step in the sequence, and the one stage that is not filtration at all; it’s there to address what a filter cannot catch.
Removes rust, dirt, sand, and large particles common in municipal lines.
Reduces chlorine, odors, colors and chemicals common in municipal water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for hard-water homes in South Florida.
Kills 99.99% of bacteria, viruses, and microorganisms.

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 (not filtration). It’s included in the price on every system we install in Leisure City.

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 Leisure City homes dealing with hard water from South Florida’s limestone aquifer. 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.
