At first I have doubts on taking this until I met Thomas. Definitely clear and understanding why I needed this for my family. And from day one til now going to 3years I have no regrets taking from this company! Service is superb! From just normal water filter to taking up water dispenser too! Definitely highly recommended in the whole industrial..my family and me specially had been healthy throughout after having this water alkaline fix compare to last few years. Thank you and appreciate all this services and helps. Purity singapore is the best!
