See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Runnymede family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—so water is purified on demand, ideal for busy Runnymede households.
First cartridge captures rust, dirt, sand, and large particles—helpful for Florida water conditions before water reaches later stages.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Florida water.
The heart of the system—rejects dissolved solids and heavy metals and sends the concentrate to the drain.
Final cartridge that polishes the water and adds beneficial minerals back for a balanced pH—great for Florida living.
Filtration Stages
Each stage handles what the one before it left behind—helping with common Florida issues like mineral scale and, for some homes, well-water contaminants such as iron or sulfur. UV is the fourth step and the one stage that is not filtration at all; it tackles what a filter cannot catch.
Removes rust, dirt, sand, and large particles—great as a first step for Florida water.
Reduces chlorine, odors, colors, and chemicals for cleaner-tasting water in Runnymede.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for many Florida water sources.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals back for a balanced, healthy pH.
Four filtration stages plus UV sterilization. Steps 1–3 and 5 are filtration stages; step 4 is the built-in UV lamp for disinfection. It’s included in the price on every system we install in Runnymede.

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—great for Runnymede homes dealing with mineral scale and possible well-water contaminants. 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.
