See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Narcoossee family—whether you’re on municipal supply or a private well.
The System Itself
Designed to fit under your sink and connect with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, a great fit for Narcoossee kitchens.
First-stage cartridge that catches rust, dirt, and sand—great for Narcoossee homes on municipal water or private wells.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for municipal water in Narcoossee.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain, even when well water varies in Narcoossee.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Narcoossee’s moderate hardness.
Filtration Stages
Each stage handles what the one before it left behind—helpful in Narcoossee where water can come from municipal supply or private wells. UV is the fourth step in the sequence, and the one stage that is not filtration at all; it is there to deal with what a filter cannot catch.
Removes rust, dirt, sand, and large particles—helpful for variable well water.
Reduces chlorine, odors, colors, and chemicals—common concerns in Narcoossee water.
Removes up to 99% of dissolved solids, heavy metals, and more—performance depends on your Narcoossee water source.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—especially helpful with Narcoossee’s moderate hardness.
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 Narcoossee.

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 Narcoossee homes on municipal water or private wells. 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.
