See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Christmas, FL families on hard well water.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the filtration stages, with a UV chamber inline. There’s no bulky storage tank, so water is purified on demand—ideal for Christmas homes on private wells.
The first cartridge—catching rust, dirt, sand, and larger particles common in well water before anything downstream sees them.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—helpful for iron/sulfur smells common in well water.
The heart of the system—rejecting dissolved solids and heavy metals, then sending the concentrate to the drain (important with hard well water).
The final cartridge polishes the water and adds beneficial minerals back for balanced pH—great for Christmas, FL well water.
Filtration Stages
Each stage handles what the one before it left behind—helpful for Christmas-area well water that can be hard and sometimes carry iron/sulfur odors. 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 often found in rural well water.
Reduces chlorine, odors, colors, and chemicals for cleaner-tasting water in Christmas.
Removes up to 99% of dissolved solids, heavy metals, and more—ideal for hard Central Florida well water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—nice for Christmas well water.
Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are the filtration stages; step 4 is the built-in UV lamp for disinfection—included in the price on every system we install in Christmas.

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 Christmas homes on private wells in rural Orange County. 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.
