See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Carlton’s humid subtropical lifestyle.
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. There’s no bulky storage tank, so your Carlton home gets purified water on demand—not water sitting and waiting.
The first cartridge traps rust, dirt, and sand—helpful in Carlton where water quality can vary between municipal and well sources.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—ideal for Carlton water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain, whether you’re on Carlton municipal water or a private well.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Carlton households.
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 filters can’t catch, especially helpful in Carlton where water sources can vary.
Removes rust, dirt, sand, and large particles—ideal for Carlton well or municipal water.
Removes chlorine, odors, colors and chemicals from Carlton water.
Removes up to 99% of dissolved solids, heavy metals, and more—performance varies with Carlton source water.

Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are the four filtration stages; step 4 is the built-in UV lamp (disinfection, not filtration). It’s included in the price on every system we install in Carlton.

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 Carlton homes on either municipal water or private wells. 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.
