When using A. O. Smith A6 RO Water Purifier, 100% of the water passes through the unique patented side stream RO membrane and is further purified by Silver Charged Membrane Technology (SCMT). Compare this with ordinary RO + UV water purifiers where some water is made to bypass the RO membrane and purity is compromised.

MIN-TECH (Mineraliser Technology) restores essential minerals to water, making your water healthy and tasty. A6 gives you the most complete mineral water station at a compact and beautiful package, giving you safe water at the security and convenience at your home.

And with its 10 liter storage capacity, water stays fresh while at the same time giving you just enough to last during those unexpected daily droughts. DOH Registered
