See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Fairlawn 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 stages, plus an inline UV chamber. No bulky storage tank—so you get purified water on demand (ideal for Fairlawn’s humid subtropical climate).
The first cartridge catches rust, dirt, and sand—helpful with Florida groundwater—before anything downstream sees them.
Carbon block media removes chlorine, odors, colors, and chemicals before the membrane—great for Fairlawn tap water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain, even with hard Fairlawn water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Fairlawn households.
Filtration Stages
Each stage handles what the one before it leaves behind—especially helpful in Fairlawn, where groundwater from limestone aquifers often means hard water and scale. UV is step four, and it’s not filtration at all; it’s there to handle what filters can’t catch.
Removes rust, dirt, sand and large particles—common in groundwater-fed Florida systems.
Removes chlorine, odors, colors, and chemicals from your Fairlawn water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful with hard, scale-prone Fairlawn water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH for Fairlawn drinking water.
Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are filtration; step 4 is the built-in UV lamp for disinfection. It’s included in the price on every system we install in Fairlawn.

Tankless purification as you draw—great for Fairlawn living, with no storage tank and no waiting.
The built-in UV lamp helps eliminate bacteria, viruses, and microorganisms—beyond what filters alone 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 Fairlawn homes dealing with hard, limestone-aquifer groundwater and scale. 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.
