See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Placid Lakes well water and hard-water scale concerns.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, with a UV chamber inline. No bulky storage tank—so in Placid Lakes homes on well water, you get purified water on demand instead of it sitting and waiting.
First cartridge: catches rust, dirt, sand, and sediment—great for Placid Lakes well water before it reaches the next stages.
Carbon block media that reduces chlorine, odors, colors and chemicals ahead of the membrane—ideal for many Placid Lakes water sources.
The heart of the system—rejecting dissolved solids and heavy metals, then sending the concentrate to the drain (helpful for hard well water in Placid Lakes).
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Placid Lakes households.
Filtration Stages
Each stage handles what the one before it leaves behind—especially helpful for Placid Lakes well water with higher mineral content. 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.

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 Placid Lakes homes on hard 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.
