Water Sense® Certification

Water Sense® is a voluntary public-private partnership program sponsored by the U.S. Environmental Protection Agency (EPA). The program seeks to help consumers make smart water choices that save money and maintain high environmental standards without compromising performance. Products and services that have earned the Water Sense label are verified to be at least 20 percent more efficient without sacrificing performance.

NSF International plays a key role in this program as we are an EPA-licensed certification body. This means that NSF is approved to test and certify products to the Water Sense specification as designated by the EPA and is authorized to grant the Water Sense label for certain products.
