Product Testing & Certification<\/strong><\/h2>\n

NSF International has established consensus standards and testing protocols for drinking water treatment devices used by all other testing laboratories. Once a system has become NSF-certified, the consumer can feel confident it will perform up to the manufacturer’s claim. For comparison purposes, we’ve listed each NSF International standard, which has been adopted by many states for drinking water treatment systems.<\/p>\n

Here are the different NSF Standards that relate to drinking water treatment and what you need to know about them:<\/p>\n

\nNSF Standard 42<\/strong><\/h2>\n

You’ll want to look for NSF 42, which deals with any claims of taste, odor, color, and other aesthetic effects, including reducing chlorine and particulate matter. The classes are as follows:<\/p>\n

Certified drinking water treatment devices have been grouped into the following categories based on the efficient reduction of chlorine throughout the system’s life.<\/p>\n
