Sparkling, hot, cold - from one tap.
Three styles of water from a single plumbed-in unit. 4-stage RO purified, carbonated on demand. No cans, no cases, no recycling bin full of empty La Croix.
Three styles. Zero bottles.
The S4 Sparkling - three waters from one tap.
A single plumbed-in unit that delivers sparkling, hot, and cold water - all RO purified. Built for offices that want a real alternative to the bottled-sparkling habit. Available countertop, or on an optional floor-standing stand.
- Sparkling, hot, and cold from one dispenser
- Countertop or floor-standing (optional stand)
- 4-stage RO: sediment → carbon → RO membrane → re-mineralizing post-carbon
- ~90% of total dissolved solids removed, re-mineralized for taste
- UV sanitization; UV lamp replaced every 5 years
- Annual filter service, included on your plan
Fresh fizz, every pour.
Short version: clean water in, CO2 added at the tap, fizz out. No bottling, no shelf life, no going flat in a fridge.
RO-purified water
Your cold-water line runs through the same 4-stage reverse osmosis used on our cooler units - sediment, carbon, RO membrane, re-mineralizing.
Carbonated at the tap
The S4 has a built-in CO2 module that infuses the cold RO water with carbonation just before it dispenses - not hours earlier in a bottle.
No flat, no stale
Because fizz is made on demand, every glass tastes the same as the first. No half-drunk cans going flat on desks.
Want ice too? The S4 and the I 14 pair up.
The S4 serves sparkling, hot, and cold. It does not do ice. If your office wants ice as well, our I 14 water + ice unit delivers hot, cold, and ice on a second dispenser - we often install the two side-by-side for teams that want everything.
Our 4-Stage Filtration Process
Every RO Living Water system uses the same 4-stage reverse-osmosis path: sediment pre-filter, carbon block, RO membrane, post-carbon polish. Removes ~90% of total dissolved solids.
-
Stage 1 · Sediment
Removes dirt, silt, rust, pipe residue, and microplastics
-
Stage 2 · Carbon block
Reduces chlorine, chemicals, and pesticides
-
Stage 3 · RO membrane
Reduces dissolved solids, pharmaceuticals, and metals
-
Stage 4 · Post-carbon polish
Polishes taste and adds minerals back for flavor
