See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Fern Park families dealing with hard, mineral-rich water.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber in-line. There’s no bulky tank, so you get purified water on demand—great for Fern Park kitchens.
The first cartridge catches rust, dirt, sand, and sediment before it can add to Central Florida limescale issues downstream.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—great for mineral-rich Central Florida water.
The heart of the system—rejecting dissolved solids and heavy metals, then sending the concentrate to the drain (helpful with hard water in Fern Park).
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—ideal for Fern Park homes.
Filtration Stages
Each stage handles what the one before it left behind. Here in Seminole County, mineral-rich groundwater can leave buildup behind—UV is step four, and it is not filtration at all. It is there to handle what a filter cannot catch.
Removes rust, dirt, sand, and large particles common in mineral-rich groundwater.
Reduces chlorine, odors, colors, and chemicals—ideal for Fern Park tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for hard Fern Park water.
Kills 99.99% of bacteria, viruses, and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for Fern Park households.
Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are filtration; step 4 is the built-in UV lamp for disinfection—included in the price on every system we install in Fern Park.

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 Fern Park homes dealing with Central Florida’s mineral-rich, hard groundwater and limescale. 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.
