See the purity, trust the technology. This tankless under-sink system delivers ultra-pure, clean, refreshing water on demand—built for Bear Hollow families and the hard, limestone-aquifer water common across Florida.
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—great for Bear Hollow homes dealing with hard, limestone-aquifer water.
The first cartridge catches rust, dirt, and sand—helpful in Florida where mineral sediment can show up with hard groundwater.
Carbon block media that reduces chlorine, odors, colors and chemicals ahead of the membrane.
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—nice for Bear Hollow’s hard-water area.
Filtration Stages
Each stage handles what the one before it left behind—helpful for Bear Hollow’s hard, mineral-heavy water. UV is the fourth step and the one stage that isn’t filtration at all; it’s there to handle what filters can’t catch.
Removes rust, dirt, sand, and large particles—helpful with Florida’s hard-water sediment.
Reduces chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
Four filtration stages plus UV sterilization. Steps 1–3 and 5 are the four filtration stages; step 4 is the built-in UV lamp for disinfection. It’s included in the price on every system we install in Bear Hollow.

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 Bear Hollow’s hard, limestone-aquifer water that can leave mineral scale behind. 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.
