See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Orlando families.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges deliver the four filtration stages, and a UV chamber sits inline between them. There’s no bulky storage tank—so in Orlando’s warm, humid climate, water is purified on demand instead of sitting and waiting.
The first cartridge captures rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that removes chlorine, odors, colors, and chemicals—helpful when seasonal rains shift Orlando-area source water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—ideal for Orlando’s moderate hardness.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Orlando drinking water.
Filtration Stages
Each stage handles what the one before it left behind. In Central Florida’s warm, humid climate—where biofilm can be a concern—UV is the fourth step, and it’s not filtration at all. It’s there to handle what filters can’t catch.
Removes rust, dirt, sand and large particles.
Removes chlorine, odors, colors and chemicals from Orlando-area tap water.
Removes up to 99% of dissolved solids, heavy metals and more from Orlando-area tap water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for Orlando 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—especially helpful in Central Florida’s warm climate and 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 Central Florida kitchens. 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.
