See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Bluefield family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings—great for Bluefield kitchens. Four quick-change twist cartridges handle the four filtration stages, with a UV chamber inline between them. There’s no bulky storage tank, so water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that reduces chlorine, odors, colors, and chemicals—helpful for Bluefield municipal 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 Bluefield’s hard water.
Filtration Stages
Each stage handles what the one before it left behind—helpful for Bluefield homes where water quality can vary between city water and private wells. UV is step four, and it’s not filtration at all; it targets what filters can’t catch.
Removes rust, dirt, sand and large particles—ideal for Bluefield well or municipal water.
Reduces chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals and more.
Kills 99.99% of bacteria, viruses and microorganisms.

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 Bluefield’s hard water and humid subtropical climate. 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.
