See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Zellwood families and Central Florida’s mineral-rich groundwater.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the filtration stages, with a UV chamber inline. There’s no bulky storage tank, so you get purified water on demand—perfect for busy Zellwood households.
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 before the membrane—great for Central Florida water.
The heart of the system—rejecting dissolved solids and heavy metals, and sending the concentrate to the drain (helpful with hard Central Florida groundwater).
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Zellwood taste.
Filtration Stages
Each stage handles something the one before it left behind. Here in Orange County, mineral-rich groundwater can be tough on plumbing—UV is step four, and it’s not filtration at all. It targets what filters can’t catch.
Removes rust, dirt, sand, and larger particles common in mineral-rich Central Florida water.
Reduces chlorine, odors, colors, and chemicals common in Central Florida tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—ideal for hard Central Florida water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals back for a balanced, healthy pH—without the bottled-water hassle in Zellwood.
Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are the four filtration stages; step 4 is the built-in UV lamp for disinfection. It’s included in the price on every system we install in Zellwood.

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 Zellwood homes dealing with hard, mineral-rich groundwater. 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.
