I just want everything to know that aqua fresh is not a professional company . I guess it is a sort of cheap company set up to take advantage of people like me who, before buying knowledge less about RO system. There customer service centre run by matriculate girls who do not even know how to talk .I will get a pure and filter water from which several diseased caused due to contaminated water such as loose motion and stomach pain and vomiting can be avoided in markets several ones are available but that company does not sure for verification of certificate the water purifier. According to me it has been a well purifier which has a good design and but colour is not good.
