The NSF drinking water treatment unit testing and certification program includes standards to address the wide variety of point-of-use (POU) and point-of-entry (POE) drinking water treatment technologies on the market today, with more than 3,000 systems and 2,000 components currently certified under seven NSF/ANSI standards. These seven technology-specific standards are listed in Table 1.

Residential water filters come in all shapes and sizes. From small faucet-mount systems and pour-through pitchers to under-the-counter plumbed-in systems and large point-of-entry (POE) whole-house systems, the choices are endless for consumers looking for a water filtration system.

Certification overview for POE & POU products
The creeks flowing from the peaks of the Rocky Mountains provide a good source of drinking water for the residents of East Shoshone County, Idaho. For decades, drinking water for approximately 1,400 households came from that surface water, which was treated only by chlorination.

Whole house filtration systems are the end of the line in defense against contaminated water. They are becoming more popular as a non-visible way (compared with end of faucet filters) to ensure safety at point of entry in the house.
POE Filter Addresses Contaminant Concerns
Although the basic components of any filtering system include the filter console, the communications link, the actuators and the instrumentation, it is the turnkey integration of these components into a pre-packaged, pre-engineered and even pre-programmed system that merits its classification as a major step forward.
