See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for you and your family here in Rood, FL.
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 the water is purified on demand rather than sitting and waiting—perfect for busy Rood households.
The first cartridge traps rust, dirt, sand, and larger particles before water moves through the rest of the system.
Carbon block media that reduces chlorine, odors, colors, and chemicals ahead of the membrane—ideal for Rood water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge, polishing the water and adding beneficial minerals back for a balanced pH—great for Rood, FL.
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, especially helpful for some Rood-area well water.
Removes rust, dirt, sand, and large particles—helpful for mineral-rich Florida groundwater.

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—great for Rood homes on city water or private wells. 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.
