See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Lake Buena Vista families and the Orlando metro lifestyle.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so you get purified water on demand—great for Lake Buena Vista kitchens and condos.
The first cartridge catches rust, dirt, sand, and large particles—helpful with Orlando-area hard water and scale.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—ideal for Orlando-area municipal water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—helpful with hard Orlando-area water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Lake Buena Vista homes.
Filtration Stages
Each stage handles something the one before it left behind. In the Orlando metro (including Lake Buena Vista), hard municipal water can leave scale behind—so the sequence matters. UV is the fourth step and the one stage that is not filtration at all; it addresses what a filter cannot catch.
Removes rust, dirt, sand, and large particles—before they add to hard-water scale buildup.
Removes chlorine, odors, colors and chemicals from Lake Buena Vista tap water.
Removes up to 99% of dissolved solids, heavy metals and more—helpful with hard Orlando-area water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for Lake Buena Vista drinking water.
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—not filtration—and it’s included in the price on every system we install in Lake Buena Vista.

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 Lake Buena Vista homes and condos. 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, helping tackle the hard municipal water common across the Orlando area, and sends 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.
