See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Benbow households—especially helpful with Florida’s hard-water mineral scale.
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, and a UV chamber sits inline between them. With no bulky storage tank, Benbow families get purified water on demand—no sitting, no waiting.
First cartridge traps rust, dirt, sand, and larger particles—before anything downstream sees them.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Benbow tap water.
The heart of the system—rejecting dissolved solids and heavy metals, then sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—ideal for Benbow’s hard-water area.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with Florida’s limestone-based aquifers and the hard-water minerals they can leave behind. UV is step four and isn’t filtration at all; it targets what filters can’t catch.

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—perfect for Benbow homes dealing with Florida’s limestone-aquifer hard water. 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.
