A Water Filter for home aims at either removing or significantly reducing ( to approved levels that is not harmful to the human body) of contaminants in the incoming water. It effectively does this using one of the 3 popular processes or a combination of them – by passing it through specialised barriers ( physical removal), adsorption via high-quality Carbon filters (chemical removal) and UV light treatment. What a Water Purifier does is that it de-mineralises the already filtered water making it “empty” of all essential minerals needed for the human body.
