There is a difference between water filters and water purifiers: Filters are used to remove suspended particulates in water. Water purifiers are designed to remove, kill, or inactivate bacteria or any other disease-causing organisms.
• Most water home water treatment devices are certified by American National Standards Institute (ANSI) using ANSI/NSF standards.
• The National Sanitary Foundation (NSF) is an excellent resource for anyone who is considering purchasing a water treatment system. It is an independent, non-profit group of scientists, engineers, technicians, educators and analysts who test and certify drinking water treatment (and other) equipment. At their Web site, www.nsf.org, you can find out if a particular product is certified to perform as advertised. When purchasing equipment, check to see if it has the NSF mark or listing on it. Understand that some systems may be NSF tested but not NSF certified.
• It is better to spend more on a certified water filter or purifier than settle for a cheap one that could cause more health problems.
