See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Miami Beach living in a hot, humid climate.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings—perfect for Miami Beach condos and kitchens. 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 water is purified on demand rather than sitting and waiting.
First-stage cartridge that catches rust, dirt, sand, and larger particles before they move through your system.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for Miami Beach tap water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—helpful with hard South Florida water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Miami Beach drinking water.
Filtration Stages
Each stage handles what the one before it left behind—helpful with the hard municipal water common in South Florida. UV is the fourth step in the sequence and the one stage that is not filtration at all; it handles what a filter cannot catch.
Removes rust, dirt, sand and large particles.
Removes chlorine, odors, colors and chemicals from Miami Beach tap water.
Removes up to 99% of dissolved solids, heavy metals and more—helpful with hard South Florida water.
Kills 99.99% of bacteria, viruses and microorganisms.

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 Miami Beach kitchens where space matters. 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.
