See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Cardwell home.
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—perfect for busy Cardwell households in our humid subtropical climate.
Stage 1 filtration—catches rust, dirt, and sand before it reaches the rest of your system.
Carbon block media that takes out chlorine, odors, colors and chemicals ahead of the membrane—great for Cardwell water sources.
The heart of the system, rejecting dissolved solids and heavy metals—great when Cardwell water quality varies by source.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Cardwell homes.
Filtration Stages
Each stage handles what the one before it left behind. UV is the fourth step, and it isn’t filtration at all—it’s there to address what filters can’t catch, a smart extra layer for Cardwell water.
Removes rust, dirt, sand, and large particles—common in both city water and private wells.
Removes chlorine, odors, colors and chemicals—ideal for many Cardwell, FL water supplies.

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 Cardwell homes where water quality can vary between municipal supply and private wells. 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.
