See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Cutler Bay families dealing with South Florida’s hard municipal water.
The System
Designed for Cutler Bay kitchens: the 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. With no bulky storage tank, you get purified water on demand—fresh in our hot, humid South Florida climate.
The first cartridge catches rust, dirt, sand, and large particles—helpful with South Florida’s hard municipal water.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for Miami-Dade tap water.
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 Cutler Bay drinking water.
Filtration Stages
Each stage handles something the one before it left behind—ideal for South Florida’s commonly hard municipal water. UV is the fourth step and the one stage that is not filtration at all; it is there to deal with what a filter cannot catch.

The built-in UV lamp helps eliminate bacteria, viruses, and microorganisms a filter can’t 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—perfect for Cutler Bay kitchens. 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. It’s also a smart way to help combat scale issues common with South Florida’s hard municipal water.
