What Are the Requirements?

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.

Not All Filters Are Created or Tested Equal

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.

A Mechanical Barrier

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.

Turnkey Automation Available To Water Works Industry

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.
