See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Merritt Island families—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—ideal for Merritt Island kitchens. Four quick-change twist cartridges provide four filtration stages, with an inline UV chamber. No bulky storage tank, so water is purified on demand.
The first cartridge catches rust, dirt, sand, and sediment—great for Merritt Island homes on municipal water or private wells.
Carbon block media that reduces chlorine, odors, color and chemicals—great for Brevard County municipal water ahead of the membrane.
The heart of the system, rejecting dissolved solids and heavy metals—helpful for Merritt Island well users concerned about mineral content.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Merritt Island tap or well water.
Filtration Stages
Each stage handles what the one before it left behind—helpful for Merritt Island homes on municipal water or private wells. UV is the fourth step and the one stage that isn’t filtration at all; it targets what filters can’t catch.
Removes rust, dirt, sand, and large particles—ideal for Merritt Island well or municipal supply.
Reduces chlorine, odors, color and chemicals common in municipal water.
Removes up to 99% of dissolved solids, heavy metals and more—great for moderate-hard water in coastal Brevard County.
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—ideal for Merritt Island well owners with occasional taste/odor concerns. It’s included in the price on every system we install.

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 Merritt Island homes on municipal supply 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.
