If you still can't decide whether or not you need some sort of water filter in your home read on.

Even if the water leaves the source in a relatively clean state, the practice of making water safe to drink actually involves adding large amounts of extremely poisonous chemicals to it. Tap water is treated with a large number of chemicals in order to kill bacteria and other microorganisms. And, water travels through pipes, which may have been underground for a very long time. It is almost impossible for the water not to become contaminated by something undesirable.  In addition, it may contain other undesirable contaminants like toxic metal salts, hormones and pesticides, or it may become contaminated by chemicals or microbes within pipes (e.g. lead, bacteria, protozoa).

Typical Tap Water Content:

• Chlorine  Fluorine compounds
• Trihalomethanes (THMs)
• Salts of: arsenic,  radium,  aluminum,  copper,  lead,  mercury,  cadmium,  barium
• Hormones
• Nitrates
• Pesticides
