See the purity, trust the technology. This tankless under-sink system delivers ultra-pure, clean, refreshing water on demand—great for Gulf Stream’s coastal Palm Beach County water.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges deliver the filtration stages, with a UV chamber inline. With no bulky storage tank, you get purified water on demand—ideal for Gulf Stream homes in coastal Palm Beach County.
The first cartridge catches rust, dirt, sand, and large particles—helpful with coastal Palm Beach County water.
Carbon block media that reduces chlorine, odors, colors and chemicals before 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 left behind—helpful with the hard municipal water common along coastal Palm Beach County. UV is step four, and it’s not filtration at all; it addresses what a filter can’t catch.
Removes rust, dirt, sand, and large particles—great for coastal Palm Beach County homes.

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 Gulf Stream homes dealing with typically hard municipal water in coastal Palm Beach County. 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.
