Residential Water Treatment

NSF writes standards and provides testing and certification services for point-of-use (POU) and point-of-entry (POE) drinking water treatment systems and components.  Testing can include material safety, structural integrity and contaminant reduction testing.  We certify thousands of products to various local and global standards, and can help you access new international markets such as China, Brazil, Australia, the Middle East, Africa and many others. Get certified by NSF – the most widely recognized and respected certification mark in the drinking water industry.

Point-of-Use and Point-of-Entry (POU/POE) Systems

Drinking water safety is a top concern of consumers. Whether your product helps reduce harmful cysts and bacteria, or simply reduces unpleasant taste, odor or discoloration, certification to an NSF standard can help ensure that your product is safe and performs as claimed.

NSF is proud to run the world’s largest POU/POE test facility   with 30 state-of-the-art water filter test rigs. Our capabilities are unmatched and include full chemical, microbiological and physical testing as well as complete in-house toxicology expertise.

Residential Drinking Water Treatment Standards

NSF developed its first drinking water treatment standard in 1973. Today, we test to seven point-of-use/point-of-entry (POU/POE) drinking water treatment standards and have certified thousands of systems and components.

The NSF POU/POE standards address the wide array of drinking water treatment technologies on the market today, including adsorptive medias, ion exchange, reverse osmosis, ceramic filters, pleated filters, ultraviolet (UV), distillation, reduction-oxidation (redox), shower filters and more.

Each NSF standard sets thorough health requirements and performance criteria for specific types of products. Contaminant reduction claims can be certified under each standard and can vary according to each water treatment technology capability. Systems that utilize more than one treatment technology may be certified under multiple standards.

Residential Drinking Water Treatment Protocols

We have the unique ability to develop new protocols for testing and certification based on our customer’s needs. Much like traditional NSF standards, protocols are developed through a collaborative process involving a technical panel, including the product manufacturer, regulators, academicians, end users and public health experts with relevant expertise. Unlike NSF standards, however, the development phase is confidential, protecting your proprietary interests.

By creating customized testing criteria and validating performance and product claims, we provide assurance of product performance to your customers in your desired markets.
