See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Keri families across Okaloosa County.
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 rather than sitting and waiting—ideal for busy Keri kitchens.
The first cartridge catches rust, dirt, sand, and larger particles before they move through the rest of the system.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—helpful with Panhandle groundwater taste/odor.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—great for mineral content common in Panhandle groundwater.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Keri homes.
Filtration Stages
Each stage handles what the one before it left behind—helpful for Keri and the western Panhandle, where moderate minerals can add taste/odor and scale. UV is the fourth step and the one stage that isn’t filtration at all; it’s there to handle what a filter can’t catch.
Removes rust, dirt, sand, and large particles common in Panhandle groundwater.
Reduces chlorine, odors, colors and chemicals—great for Keri water.
Removes up to 99% of dissolved solids, heavy metals and more—great for Keri’s moderate-hardness water.
Kills 99.99% of bacteria, viruses, and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for Keri drinking water.
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, which is not filtration but disinfection—installed on every system we put in across Keri and Okaloosa 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—ideal for Keri homes dealing with the Florida Panhandle’s mineral content and moderate hardness. 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.
