See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Holden Heights 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 in Holden Heights you get purified water on demand, not water sitting and waiting.
The first cartridge catches rust, dirt, sand, and sediment before it can build up in Orange County plumbing.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Orange County tap water.
The heart of the system—designed to reject dissolved solids and heavy metals, then send the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—ideal for hard Floridan aquifer water.
Filtration Stages
Each stage handles what the one before it left behind—ideal for Orange County water that often starts as hard Floridan aquifer groundwater. UV is the fourth step in the sequence 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 groundwater-fed lines.
Reduces chlorine, odors, colors, and chemicals from your Holden Heights tap.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for hard Central Florida water.
Kills 99.99% of bacteria, viruses, and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for Orange County homes on hard water.
Four filtration stages plus UV sterilization. Steps 1–3 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 Holden Heights and nearby Orange County.

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—perfect for Holden Heights homes dealing with hard Floridan aquifer water. 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.
