NSF Certification for Lead Reduction

NSF International aims to protect public health by testing and certifying water filters to ensure they reduce lead in drinking water to safe levels. Their tests confirm lead reduction between 95% and 99.9%, adhering to standards set by the WHO and Health Canada. NSF only certifies products that meet their rigorous standards. The testing process involves adding lead to water and passing it through the filter to ensure it does not exceed 10 parts per billion. Various types of filters, including pitchers and faucet-mounted ones, are certified. Consumers should look for the NSF mark when purchasing filters and can verify certification on NSF's website.
