See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Keela family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, and a UV chamber sits inline between them—helpful for Keela’s humid subtropical climate. There is no bulky storage tank, so the water is purified on demand rather than sitting and waiting.
The first cartridge catches rust, dirt, sand, and large particles before anything downstream sees them.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for humid Florida conditions.
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—great for everyday Keela drinking water.
Filtration Stages
Each stage handles what the one before it leaves behind. UV is step four—and it’s not filtration at all. It’s there to address what filters can’t catch, which matters in Florida’s humid subtropical climate.
Removes rust, dirt, sand, and large particles.
Reduces chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more (depending on your Keela source 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 for disinfection—especially helpful in humid Florida— and it’s included in the price on every system we install.

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 Keela homes. 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. In Florida’s humid subtropical climate, UV adds an extra layer of confidence where biofilm/algae concerns can come up depending on your water source. 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.
