See the purity, trust the technology. This tankless under-sink system delivers ultra-clean, refreshing water on demand—tailored to Shawnee water that can vary by utility or private well.
The System Itself
Designed to fit neatly under your sink with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. With no bulky storage tank, it purifies water on demand—great for humid subtropical Shawnee living.
The first cartridge catches rust, dirt, sand, and larger particles—helpful whether you’re on a local utility or a private well in Shawnee.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for Shawnee water sources.
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—perfect for Shawnee households.
Filtration Stages
Each stage handles something the one before it left behind. UV is the fourth step in the sequence and the one stage that is not filtration at all - it is there to deal with what a filter cannot catch, which matters when Shawnee water comes from different sources.
Removes rust, dirt, sand and large particles—ideal for Shawnee homes on wells or utility water.
Helps reduce chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more (performance depends on Shawnee source water).
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
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—and it’s included in the price on every system we install in Shawnee.

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. In Shawnee, water quality can vary by local utility or private well—so we often recommend testing to pinpoint mineral content and treatment needs. 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.
