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, and a UV chamber sits inline between them. No bulky storage tank—just purified water on demand for Lake Butler homes, including well-water setups.
The first cartridge catches rust, dirt, sand, and grit—great for Floridan aquifer well water common around Lake Butler.
Carbon block media that reduces odors, color, and chemicals before the membrane—great for Floridan aquifer well water.
The heart of the system—rejects dissolved solids and heavy metals, helping with mineral-rich Floridan aquifer water.
The final cartridge polishes the water and adds beneficial minerals back for balanced pH—great for Lake Butler taste.
Filtration Stages
Each stage handles what the one before it leaves behind—helpful for Lake Butler well water with mineral content and occasional iron/sulfur odors. UV is the fourth step in the sequence and the one stage that is not filtration at all—it deals 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 Lake Butler homes on Floridan aquifer well water with moderate hardness and occasional iron/sulfur odors. 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.
