See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—great for Eagle Island’s hard water.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the stages, with a UV chamber inline. No bulky storage tank—just purified water on demand for Eagle Island homes.
The first cartridge catches rust, dirt, sand, and larger particles—helpful whether your Eagle Island home is on city water or a well.
Carbon block media that reduces chlorine, odors, colors and chemicals ahead of the membrane.
The heart of the system—rejects dissolved solids and heavy metals and sends the concentrate to the drain.
Final cartridge polishes the water and adds beneficial minerals back for a balanced pH.
Filtration Stages
Each stage handles what the one before it leaves behind. In Eagle Island, where water can be hard and sources can vary, UV is step four—and it’s not filtration at all. It targets what filters can’t catch.
Removes rust, dirt, sand, and large particles—common concerns with hard water setups.
Reduces chlorine, odors, colors and chemicals.
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 filtration; step 4 is the built-in UV lamp for disinfection. It’s included in the price on every system we install in Eagle Island.

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—perfect for Eagle Island, where water can vary between municipal and private well sources. 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.
