With so many different manufacturers producing counter top, under sink, whole house, shower, pitcher, and outdoor/emergency drinking water filters, the general public sometimes needs a little guidance when trying to decide which brand of product, make or model will best address their water purification needs.

NSF International helps consumers by providing reliable product information obtained through in-depth research and controlled experimentation done solely for the purpose of making sure products perform up to the expectations/standards of their manufacturers and all applicable levels of government.

What does ‘NSF’ stand for?

NSF stands for National Sanitation Foundation and that organization has played key roles in developing standards, product testing methods and certification services in areas such as public health, public safety and environmental protection.

Why should I care about NSF certification when purchasing a product?

“NSF is widely recognized for its scientific and technical expertise in the health and environmental sciences. Its professional staff includes engineers, chemists, toxicologists, and environmental health professionals with broad experience both in public and private organizations.

NSF has earned the Collaborating Center designations by the World Health Organization (WHO) for Food and Water Safety and Indoor Environment.” (source)

And furthermore…

“Serving manufacturers operating in 80 countries …. The NSF Mark is recognized for its value in international trade around the world and is respected by regulatory agencies at the local, state, and federal levels.” (source)

OK, fine, but what does the NSF mark on a product tell me as the consumer?

By voluntarily submitting their products for independent review by an organization dedicated to ensuring compliance with American National Standards, the manufacturers of NSF Certified Products have shown a deep commitment to product integrity, public safety and preservation of the environment.
