See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Pine Castle families.
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, with a UV chamber inline. There’s no bulky storage tank, so you get purified water on demand—ideal for busy Pine Castle kitchens.
First cartridge captures rust, dirt, sand, and larger particles before they reach the rest of the system.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Orange County tap water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Central Florida water.
Filtration Stages
Each stage handles what the one before it left behind—ideal for Central Florida’s hard groundwater. UV is the fourth step in the sequence, and the one stage that is not filtration at all; it handles what a filter cannot catch.
Removes rust, dirt, sand and large particles common in groundwater-fed systems.
Reduces chlorine, odors, colors, and chemicals for cleaner-tasting water in Pine Castle.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for Central Florida water quality.
Kills 99.99% of bacteria, viruses and microorganisms.

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)—included in the price on every system we install in Pine Castle.

Built-in UV helps eliminate bacteria, viruses and microorganisms filters can’t catch.
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 Pine Castle homes dealing with Central Florida’s hard groundwater. 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.
