See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Lake Monroe family.
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. With no bulky storage tank, you get purified water on demand—great for busy Lake Monroe kitchens.
Stage 1 cartridge catches rust, dirt, sand, and larger particles—helpful when seasonal storms stir up source water off the St. Johns River.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—helpful when storm season shifts source-water conditions.
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 balanced pH—ideal for Lake Monroe’s moderate hardness.
Filtration Stages
Each stage handles what the one before it left behind. With Lake Monroe’s warm, humid climate and seasonal storm activity that can affect source-water conditions from the St. Johns River, UV is a smart fourth step—addressing what filters can’t catch.
Removes rust, dirt, sand and large particles—ideal for storm-season water changes.
Reduces chlorine, odors, colors, and chemicals in Lake Monroe tap water.
Removes up to 99% of dissolved solids, heavy metals, and more.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
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. It’s included in the price on every system we install in Lake Monroe.

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 Monroe’s humid subtropical climate and seasonal storm shifts that can affect source-water conditions. 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.
