See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—made for Corkscrew families dealing with hard Southwest Florida groundwater.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand—ideal for busy Corkscrew and Estero kitchens.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream—great for Southwest Florida well water.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for Southwest Florida water.
The heart of the system, rejecting dissolved solids and heavy metals—helpful with hard Southwest Florida groundwater—then sending concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in Lee County.
Filtration Stages
Each stage handles what the one before it leaves behind—helpful for Southwest Florida groundwater that can be hard and scale-prone. UV is the fourth step in the sequence and the one stage that is not filtration at all; it tackles 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 Corkscrew homes dealing with hard Southwest Florida 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 - 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.
