See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Lake Mary families.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, with a UV chamber inline. With no bulky storage tank, you get purified water on demand—ideal for Lake Mary homes dealing with mineral-rich (hard) water.
The first cartridge traps rust, dirt, sand, and larger particles—helpful with mineral-rich (hard) water common in Seminole County.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Lake Mary tap water.
The heart of the system, rejecting dissolved solids and heavy metals—helpful with Lake Mary’s mineral-rich (hard) water—and sending concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Lake Mary families.
Filtration Stages
Each stage handles what the one before it leaves behind—helpful for Lake Mary’s mineral-rich (hard) groundwater. UV is the fourth step in the sequence and the one stage that is not filtration at all; it’s there to handle what a filter cannot catch.

The built-in UV lamp helps eliminate bacteria, viruses, and microorganisms a filter 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—ideal for Lake Mary homes dealing with mineral-rich (hard) groundwater and scale buildup. 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.
