See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—great for Lakeside Green homes in Florida’s humid subtropical climate.
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 between them. With Florida’s humid subtropical climate, tankless on-demand purification helps avoid warm, stagnant stored water.
Stage one cartridge traps rust, dirt, sand, and larger particles before anything else flows downstream.
Carbon block media that reduces chlorine, odors, colors and chemicals ahead of the membrane.
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.
Filtration Stages
Each stage handles what the one before it leaves behind. UV is the fourth step, and it’s not filtration at all—it’s added protection for what a filter can’t catch, which matters in Florida’s warm, humid conditions.
Removes rust, dirt, sand, and large particles.
Reduces chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals and more.
Kills 99.99% of bacteria, viruses, and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
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 in Florida’s humid subtropical climate where warm, stagnant water can support microbial growth.

The built-in UV lamp helps eliminate microbes—useful in Florida’s humid subtropical climate.
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. 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—especially helpful in Florida’s humid subtropical climate, where warm, stagnant water can support microbial growth in infrequently used plumbing.
