No matter where you get your drinking water from the odds are that at some point it contained some contaminants. Some of these contaminants, such as radon and arsenic, occur naturally while others, such as microorganisms and pesticides, are introduced into the water supply from outside contact with people and animals. At low levels most contaminants are not harmful to people, but that does not mean we should have to drink them.
The easiest way to be sure that your drinking water contains as few contaminants as possible is to filter your water.
Your home may have a refrigerator with a water and ice dispenser that has a built in refrigerator filter, or you might be using another filtration system such as an under sink or whole house filter. Below is a list of popular filters and the contaminants that they remove. For more information on the common contaminants found in your drinking water please feel free to consult our Drinking Water Contaminant Glossary.
