See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Indian River Estates families dealing with hard-water scale.
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 between them. No bulky storage tank—so you get purified water on demand, ideal for Indian River Estates kitchens.
The first cartridge catches rust, dirt, and sand before it can feed scale and buildup common with local hard water.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for local tap water.
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—great for hard water areas.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with the hard-water mineral scale common across the Treasure Coast. UV is the fourth step in the sequence, and it’s not filtration at all; it’s there to deal with what a filter cannot catch.
Removes rust, dirt, sand and large particles—helpful with local hard-water conditions.
Reduces chlorine, odors, colors and chemicals for cleaner-tasting water in Indian River Estates.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for hard-water households.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals back 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 Indian River Estates.

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 Indian River Estates homes dealing with hard-water 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.
