Introducing aka+ ionised alkaline water - it's exclusive to Coles! aka+ is healthy, refreshing and tastes incredible! This is all thanks to the advanced technology used to create aka+. What makes aka+ different to many alkaline waters is the unique ionisation process - it raises the pH of the water and removes bitter ions, which can occur in water with a higher pH. aka+ is also purified using both microfiltration and reverse osmosis and has added electrolytes to give it an even better taste. While most bottled waters have a pH of 5-8, aka+ has a pH of 9.5+. Taste the difference of aka+ ionised alkaline water today!
