The newly released Nikken Waterfall PiMag Water Filter has been tested by independent labs and has earned golden seal certification to meet both NSF/ANSI standards 42 and 53 as well as 372.
There are basically three independent organizations which are established for consumer and public safety and which test and set the standards for drinking water: NSF – The Public Health and Safety Company, ANSI – American National Standards Institute, and WQA – the Water Quality Association. NSF sets the standar
WQA – the Water Quality Association. NSF sets the standard and the ANSI and WQA again certify the results by further conducting their own lab tests. So for any water filter which is certified and given a golden seal by the WQA, it can be known that rigorous testing has been conducted to scientifically validate it’s effectiveness. The Nikken Waterfall has been certified by all of the above.
There are altogether three standard tests which apply to water filters, or what NSF refers to as “Drinking Water Treatment Units”. These are standards 42, 53 and 372. Standard 42 “Aesthetic Effects” tests for the “reduction of chlorine, chloramine, taste and odor“. Standard 53 “Health Effects” tests for “reduction of specific health-related contaminants in drinking water“, and this includes the wide range of various harmful chemicals, bacterials, pesticides, pharmaceuticals, etc. that can be found in drinking water anywhere. And Standard 372 is the “Evaluation of Lead Content in Drinking Water Products“.
The WQA website states:
“Certification means that a production model of the listed line of drinking water treatment units was tested at the Water Quality Association laboratory, or any of the other testing laboratories recognized by the Water Quality Association, and was found to have met the standards for reduction of specific health-related contaminants in drinking water. In addition, the materials and components used in these certified drinking water treatment units have met the rigorous safety and structural integrity and strength requirements set by industry Standard NSF/ANSI-53.“
“The category of VOC (Volatile Organic Chemical) includes a number of chemicals that are both man-made and naturally occurring. Water from wells and utilities may contain some of these contaminants. Some VOCs are pesticides, herbicides, or insecticides that seep into the ground water after application. Other VOCs enter the water supply through industrial or other waste disposal. This category also includes total trihalomethanes, which are a by-product of chlorination.
You can see here on the WQA website where the Nikken Waterfall PiMag filter is certified for all three standards.
