See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Holopaw family—great for everyday drinking and cooking.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, with a UV chamber inline. No bulky storage tank—so in Holopaw’s humid climate, water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with rural well water around Holopaw.
Carbon block media that reduces chlorine, odors, and chemicals before the membrane—great for well-water areas around Holopaw.
The heart of the system, rejecting dissolved solids and heavy metals—helpful with moderate mineral content common in local groundwater.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Holopaw households.
Filtration Stages
Each stage handles what the one before it leaves behind—especially helpful for Holopaw homes on groundwater/well water where mineral content can be a concern. UV is step four, and it is not filtration at all; it targets what filters 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—ideal for Holopaw homes on groundwater/well water. 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.
