Parents know that water, although vital to our life can also be a danger if not carefully monitored.   Unfiltered tap water does not remove all of the contaminants that are in our water systems and some packaged bottle water like water filters.  A high quality water filter will be able to remove heavy metals such as lead, pathogens, and other contaminants.  A high quality water filtration system will install on the main water pipe, filtering all the water going into the house, thus removing pollutants from drinking and bathing water alike.  Less  expensive alternatives to a whole house filtration system would be an under sink water filter or faucet mount water filter that will filter the tap what you drink and cook with.  Water filters provide a source of pure water for those that want to live naturally.
