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


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.

Benefits of Certification

Certification to an NSF standard ensures that your product meets the regulatory requirements for the U.S., and can often meet or fulfill the testing requirements for many other countries as well. Market leaders strive to attain NSF certification as a mark of distinction that assures their customers that their product is safe for use and can effectively remove contaminants in drinking water.


Certification also allows your company to:

  • List your product in our online directory of certified drinking water treatment systems and components
  • Use the NSF certification mark on your products and in your promotional materials
