See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Lotus living in Florida’s humid subtropical climate.
The System Itself
Designed to fit under your sink in Lotus and connect with quick-connect fittings. Four quick-change twist cartridges deliver four filtration stages, with a UV chamber inline between them. With no bulky storage tank, water is purified on demand—so it’s not sitting and waiting.
The first cartridge catches rust, dirt, and sand—helpful when seasonal storms stir up water quality in Lotus.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the RO membrane—helpful in Lotus water.
The heart of the system—rejecting dissolved solids and heavy metals, then sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Lotus’s moderate hardness.
Filtration Stages
Each stage handles something the one before it left behind. In Lotus, where moderate hardness can leave mineral scale behind, the multi-stage approach helps keep water tasting clean. 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—great for Lotus storm season.
Reduces chlorine, odors, colors, and chemicals in Lotus tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—ideal for Lotus water conditions.
Kills 99.99% of bacteria, viruses, and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—great for Lotus 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 for disinfection—helpful when Florida storms can impact water quality. It’s included in the price on every system we install.

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 Lotus homes dealing with moderate mineral scale and Florida’s humid subtropical conditions. 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.
