See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for South Beach’s warm, humid climate and hard municipal water.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings—ideal for South Beach condos from SoFi to West Avenue. Four quick-change twist cartridges handle the four filtration stages, with a UV chamber inline. With no bulky storage tank, water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that removes 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.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for South Florida living.
Filtration Stages
Each stage handles what the one before it leaves behind. UV is the fourth step in the sequence—and the one stage that isn’t filtration at all. It’s there to address what a filter can’t catch, for extra peace of mind in South Beach.
Removes rust, dirt, sand and large particles—ideal for South Florida’s hard water.

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—ideal for South 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.
