See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for East Naples’s humid, coastal lifestyle.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. There’s no bulky storage tank, so you get purified water on demand—ideal for East Naples homes.
The first cartridge catches rust, dirt, sand, and larger particles before they can add to East Naples mineral scale.
Carbon block media that reduces chlorine, odors, color, and chemicals—great for hard East Naples water before the membrane.
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—helpful with the hard water common around East Naples. 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 hard water.
Reduces chlorine, odors, color, and chemicals in East Naples tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—helping fight scale from hard water.
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 filtration; step 4 is the built-in UV lamp for disinfection. It’s included in the price on every system we install in East Naples.

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 tackling East Naples’ hard water and mineral 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.
