See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for you and your family here in Lock Arbor.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand—ideal for busy Lock Arbor households.
The first cartridge—catching rust, dirt, sand, and large particles before anything downstream sees them.
Carbon block media that takes out chlorine, odors, colors, and chemicals ahead of the membrane—great for Lock Arbor tap water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—results vary by Lock Arbor source water.
The final cartridge, polishing the water and adding beneficial minerals back for a balanced pH—great for Lock Arbor drinking water.
Filtration Stages
Each stage handles what the one before it leaves behind—helpful in Lock Arbor, where water quality can vary depending on municipal supply vs. a private well. UV is the fourth step and the one stage that is not filtration at all; it handles what filters cannot 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 Lock Arbor homes on municipal water or private wells, where water quality can vary and testing matters. 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.
