Reverse Osmosis

Reverse osmosis is the only stage that takes out what is dissolved in water: salts, heavy metals, nitrates, fluoride, microplastics, bacteria and viruses, down to 0.0001 micron. Ours are the 100 GPD systems we fit in Randburg homes, with the re-mineraliser built in, so what comes out tastes like water and not like a laboratory.
