See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean and refreshing water on demand for you and your family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the seven 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.
The first cartridge, catching rust, dirt, sand and large particles before anything downstream sees them.
Carbon block media that takes out chlorine, odors, colors and chemicals ahead of the membrane.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge, polishing the water and adding beneficial minerals back for a balanced pH.
Filtration Stages
Each stage handles something the one before it left behind. UV is the fifth 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.
Removes rust, dirt, sand and large particles.
Removes chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals and more.
Improves taste and removes any remaining odors.
Kills 99.99% of bacteria, viruses and microorganisms.
Final polishing for ultra-fresh, great-tasting water.
Adds beneficial minerals for a balanced, healthy pH.
Captures any tiny particles for crystal-clear results.
Seven filtration stages plus UV sterilization. Steps 1 to 4 and 6 to 8 are the seven filtration stages; step 5 is the built-in UV lamp, which is not filtration but disinfection - it is included in the price on every system we install.

Independent Testing
You do not have to take the performance on faith. The system has been tested by an independent laboratory against the recognised standard for reverse osmosis drinking water systems.
Testing covers the removal of over 99.99% of more than 1,000 contaminants, including total dissolved solids such as fluoride, nitrates and nitrites; PFAS, PFOA and PFOS; heavy metals such as lead and arsenic; and chloride.
Made by SimPure
SimPure is based in Seattle, Washington and has served the USA since 2006, with trained water specialists available for product support.

Product Assurances
Better-tasting, odor-free water for drinking, cooking and everyday use.
The tankless design purifies as you draw, so there is no storage tank and no waiting.
The built-in lamp helps eliminate bacteria, viruses and microorganisms a filter cannot catch.
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. 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, and a second carbon block cleans up the taste. 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. Post carbon polishing, an alkaline and mineral stage and a final ultra-fine filter finish the water, putting beneficial minerals back for a balanced pH and catching any last particles. Seven filtration stages plus UV, producing up to 400 gallons a day on demand, with no bulky storage tank to hold water, take up space or invite secondary contamination.
