See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—made for Windermere families and Central Florida living.
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, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, ideal for busy Windermere kitchens.
The first cartridge—catching rust, dirt, sand, and large particles before anything downstream sees them in your Windermere home.
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.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Windermere homes.
Filtration Stages
Each stage handles what the one before it leaves behind. Here in Orange County, hard water can mean more mineral buildup over time, so a true multi-stage approach matters. UV is the fourth step and isn’t filtration at all—it targets what filters can’t catch.
Removes rust, dirt, sand and large particles common in Central Florida water.
Removes chlorine, odors, colors and chemicals—common concerns in Central Florida tap water.
Removes up to 99% of dissolved solids, heavy metals and more—helpful with hard Central Florida water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for Windermere drinking water.
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 (disinfection, not filtration). It’s included in the price on every system we install in Windermere.

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 Windermere homes. 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, helping combat Central Florida’s hard-water mineral scale, 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.
