It was totally an amazing and incredible job done by Purity Singapore Pte Ltd. Definitely the most reasonable price for water dispenser complete with under sink water filter and free replacement filter in Singapore. Deeply appreciated and thankful for the helpful advises especially installing water piping in such a way “hidden” and “out of our sights” from the main water supplies to opposite side of our table top. We will definitely recommend our relatives and friends for such a great product and friendly installer.
