See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your De Soto City family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, with a UV chamber inline between them. There’s no bulky storage tank, so your water is purified on demand—ideal for De Soto City homes.
The first cartridge catches rust, dirt, sand, and other large particles—helpful for Florida municipal or well-water supplies.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for De Soto City tap water.
The heart of the system, rejecting dissolved solids and heavy metals—helpful for Florida water that can carry minerals that lead to scale.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in De Soto City.
Filtration Stages
Each stage handles something the one before it left behind. UV is the fourth step in the sequence and the one stage that is not filtration at all - it is there to deal with what a filter cannot catch.
Removes rust, dirt, sand and large particles—common in Florida well or municipal water.
Reduces chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals and more (performance varies with De Soto City source water).
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
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 for disinfection—not filtration—and it’s included in the price on every system we install in De Soto City.

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 De Soto City’s humid subtropical homes. 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.
