See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your South Apopka family.
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. No bulky storage tank—so your South Apopka home gets purified water on demand, not water sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles—helpful for South Apopka well and groundwater-fed supplies.
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—nice for hard water areas like South Apopka.
Filtration Stages
Each stage handles what the one before it left behind—helpful for South Apopka homes on groundwater-based supply or private wells. UV is the fourth step and the one stage that is not filtration at all; it’s there to deal with what a filter cannot catch.
Removes rust, dirt, sand, and large particles—common in well and groundwater-fed water.
Reduces chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for hard-water homes in South Apopka.
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 (disinfection, not filtration). It’s included in the price on every system we install in South Apopka.

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 South Apopka homes dealing with hard-water scale from groundwater or wells. 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.
