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 in Ashton—built for real Florida living.
The System Itself
Designed to fit neatly under your sink and connect with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. With no bulky storage tank, you get purified water on demand—helpful in Ashton’s humid subtropical climate where fresh, clean-tasting water matters.
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 many Florida water supplies.
The heart of the system—rejecting dissolved solids and heavy metals, sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for balanced pH—great for Ashton kitchens.
Filtration Stages
Each stage handles what the one before it left behind. In humid subtropical Florida conditions, UV is the fourth step in the sequence—and the one stage that isn’t filtration at all. It’s there to deal with what a filter can’t catch.
Removes rust, dirt, sand and large particles.

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 Ashton, Florida homes where mineral scaling and corrosion can be concerns depending on the local groundwater source. 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.
