See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Harlem, Florida water conditions.
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 a UV chamber inline. No bulky storage tank—just purified water on demand for Harlem households.
The first cartridge catches rust, dirt, sand, and grit—common with mineral-rich groundwater in inland South Florida.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for hard-water areas like Harlem.
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 everyday drinking.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with the mineral-rich, hard water common across inland South Florida. UV is the fourth step and the one stage that is not filtration at all; it addresses what filters cannot catch.
Removes rust, dirt, sand, and large particles—helpful with inland South Florida groundwater.
Reduces chlorine, odors, colors and chemicals for cleaner-tasting water in Harlem.
Removes up to 99% of dissolved solids, heavy metals and more—great for Harlem’s mineral-rich groundwater.

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 Harlem, FL homes on mineral-rich groundwater. 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—extra peace of mind during Southwest Florida’s storm season when private wells can be impacted—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.
