8. Do water filters work and should I use one?
As with most products, some filters work better than others and some do not work at all. There are many types of filters available, each type works differently and will remove different substances from the water. It will be very helpful for you to know exactly why you want to filter the water before you speak to the seller of water treatment devises. If you choose to filter your water, there are several resources available to you to assist you in choosing a filter that works properly and will meet your needs. Consumer Reports Magazine occasionally will compare types of water filters and explain which types remove which constituents. They also compare various models and report on which ones work the best. A list of National Sanitation Foundation (NSF) approved water treatment devices is available by calling the NSF at (800) 673-8010.

Please note: If you do install a water filter, follow the operating and maintenance instructions very carefully. An improperly installed and/or maintained filter can adversely affect the water quality. The water provided by the DuPage Water Commission meets all State and Federal drinking water standards.
