I brought PureH2O brand from america. Both filter and shower! Errr let me get some links for your review.
This guy tested. Apparently this is a filter plus slightly Alkaline which is what our blood PH is supposed to be. http://youtu.be/-Gg7hL-MEWw?list=PLkqUPbg8hzKMHUjWF252vWCRUwJNeM4ve This one is the one i used for installation. I brought from America for SGD150 with shipping lol. http://global.shop.com/eatprayshop/index.cfm?action=shopping.gpcProduct&prodID=3825451&refEmail=07030D2E091B0636042604100158002408
