See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Sanford families dealing with hard Seminole County 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. No bulky storage tank—so in humid Sanford kitchens, water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, and sand—helping protect your system from Seminole County’s hard-water scale issues downstream.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for 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—great for hard Seminole County water.
Filtration Stages
Each stage handles what the one before it left behind—ideal for Seminole County municipal water, where hardness can lead to scale. 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—great for Seminole County hard water.
Reduces chlorine, odors, colors and chemicals common in municipal water.
Removes up to 99% of dissolved solids, heavy metals and more—helping combat hard-water issues common in Seminole County.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for everyday drinking in Sanford.
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 Sanford.

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 Sanford homes on Seminole County municipal water, where hard water can contribute to scale. 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.
