A home water treatment unit can improve water's taste, or provide an extra margin of safety for people more vulnerable to the effects of waterborne illness (people with severely compromised immune systems and children may have special needs). Consumers who choose to purchase a home water treatment unit should carefully read its product information to understand what they are buying, whether it is a better taste or a certain method of treatment. Be certain to follow the manufacturer's instructions for operation and maintenance, especially changing the filter on a regular basis.
Environmental Protection Agency sets standards for tap water provided by public water systems; the Food and Drug Administration sets bottled water standards based on Environmental Protection Agency's tap water standards.
