See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Leesburg family—without a bulky tank taking up space.
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, and a UV chamber sits inline between them. There’s no bulky storage tank—so you get purified water on demand, ideal for busy Leesburg households.
The first cartridge catches rust, dirt, sand, and large particles—helpful for Central Florida water before it reaches your glass.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Leesburg tap water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain, even with hard Central Florida water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—nice for Lake County’s hard water.
Filtration Stages
Each stage handles what the one before it left behind—helpful with Central Florida’s hard water from limestone aquifers. 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 Lake County water.
Reduces chlorine, odors, colors, and chemicals from Leesburg municipal water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful with hard Central Florida water.
Kills 99.99% of bacteria, viruses, and microorganisms.
Adds beneficial minerals back for a balanced, healthy pH—popular in Lake County homes.
Four filtration stages plus UV sterilization. Steps 1–3 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 Leesburg.

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—great for Leesburg homes dealing with Central Florida’s hard water from limestone aquifers. 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.
