See the purity, trust the technology. A tankless under-sink system delivering ultra-pure, clean, refreshing water on demand for your Gandyville family.
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 Gandyville 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—great for Gandyville tap water.
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 drinking in Gandyville.
Filtration Stages
Each stage handles something the one before it left behind. UV is the fourth 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 for Gandyville homes.
Removes rust, dirt, sand, and large particles common in tap lines.
Removes chlorine, odors, colors, and chemicals from your Gandyville water.
Removes up to 99% of dissolved solids, heavy metals and more.

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 (disinfection, not filtration) and it’s included in the price on every Gandyville installation.

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—perfect for Gandyville kitchens. 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.
