See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for LaBelle’s mineral-rich water and busy households.
The System Itself
Designed to fit neatly under your sink with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with an inline UV chamber. No bulky storage tank—just purified water on demand for LaBelle homes.
The first cartridge catches rust, dirt, sand, and large particles before they can add to LaBelle’s mineral buildup.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for mineral-rich LaBelle water.
The heart of the system—rejects dissolved solids and heavy metals and sends the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with LaBelle’s mineral-rich, hard water. UV is the fourth step and the one stage that isn’t filtration at all; it’s there to handle what a filter can’t catch.
Removes rust, dirt, sand, and large particles common in mineral-rich LaBelle water.
Reduces chlorine, odors, colors, and chemicals from LaBelle tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—helping cut down the effects of hard water in LaBelle.
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 for disinfection—included in the price on every system we install in LaBelle.

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 LaBelle kitchens where mineral-rich (hard) water can lead to limescale. 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.
