See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Geneva family—built for mineral-rich Central Florida water.
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. There’s no bulky storage tank—so you get purified water on demand, a big plus in humid Central Florida kitchens.
The first cartridge catches rust, dirt, sand, and larger particles—great for mineral-rich Seminole County groundwater.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for mineral-rich Seminole County water.
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—ideal for hard-water areas of Seminole County.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with Seminole County’s mineral-rich groundwater. UV is the fourth step in the sequence, and the one stage that is not filtration at all; it’s there to deal with what a filter cannot catch.
Removes rust, dirt, sand, and large particles common in Seminole County groundwater.
Reduces chlorine, odors, colors, and chemicals for cleaner-tasting Geneva water.
Removes up to 99% of dissolved solids, heavy metals, and more—helping fight hard-water issues common in Seminole County.

Adds beneficial minerals back for a balanced, healthy pH—great for hard water in Seminole County.
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. It’s included in the price on every system we install in Geneva and across Seminole County.

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 Geneva homes on mineral-rich groundwater in Seminole County. 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.
