See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—great for Montverde families dealing with hard, mineral-rich Lake County groundwater.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the filtration stages, with a UV chamber inline. There’s no bulky storage tank, so you get purified water on demand—ideal for Montverde kitchens and bar sinks.
The first cartridge traps rust, dirt, and sand—helpful with Lake County’s mineral-rich water before it reaches later stages.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Lake County water.
The heart of the system—rejecting dissolved solids and heavy metals, and sending the concentrate to the drain (helpful with Lake County’s mineral-rich water).
The final cartridge polishes the water and adds beneficial minerals back for balanced pH—great for hard Lake County water.
Filtration Stages
Each stage handles what the one before it leaves behind—helpful for Lake County’s mineral-rich water. UV is the fourth step in the sequence and the one stage that is not filtration at all; it’s there to address what a filter cannot catch.
Removes rust, dirt, sand and large particles—common with mineral-rich Lake County water.
Reduces chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for hard water common in Lake County.
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. It’s included in the price on every system we install in Montverde.

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 mineral-rich Lake County water that can cause 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.
