There are home treatment units that are certified to remove perchlorate from drinking water. EPA neither endorses nor recommends specific home water treatment units. NSF International (800-673-8010) can help you determine which home filtration systems are able to filter perchlorate. 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.
