See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Surfside’s hard water and coastal salt air.
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 UV inline. No bulky storage tank—so you get purified water on demand, a big plus in Surfside’s hot, humid climate.
The first cartridge catches rust, dirt, sand, and large particles—helpful with coastal corrosion and sediment.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for Miami-Dade tap water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain, helping combat Surfside’s hard water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Surfside families.
Filtration Stages
Each stage handles what the one before it leaves behind. UV is step four—and unlike filtration, it targets what filters can’t catch, adding extra protection for Surfside kitchens dealing with hard municipal water.
Removes rust, dirt, sand, and large particles—great for Surfside’s coastal conditions.
Reduces chlorine, odors, colors and chemicals in Surfside tap 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—great for Surfside’s hard municipal water and coastal salt air. 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.
