Some consumers may have issues related to the taste, odor, or presence of a particular contaminant in their drinking water supply. If you have or are considering the use of a home water treatment device, we encourage you to visit the Drinking Water Treatment section of the NSF website.
NSF is the leading independent tester of home water treatment. They evaluate hundreds of brands of water treatment devices each year to ensure they meet the design and performance requirements of national public health standards. Consumers can be confident that home water treatment devices that carry NSF certification will actually reduce the contaminants as claimed by the manufacturer on the product label. In addition, you can also be assured that the product itself is not adding harmful levels of contaminants to the water.
Unlike many other product testing programs, NSF-certified products must be re-certified each year; this allows them to assure consumers that the products they are using continue to meet the strict national standards for public health and safety.
Although they do not make product recommendations, the NSF Consumer Affairs Office is available to answer general questions regarding home water treatment products and the testing our organization performs on these devices. You can contact their Consumer Affairs Office via a toll-free consumer hotline at 877-867-3435 or email the Consumer Affairs Office.
