Top 6 NSF Drinking Water Filtration Standards
NSF - Leading Sanitation in Water Filtration
Who leads certification in water filtration? Three letters – NSF. There is a small blue circle with the letters NSF printed on Aquasana packaging. It’s also seen on the owner’s manuals, and other material received when un-boxing a new purchase. That badge is validation from the NSF (National Sanitation Foundation) that Aquasana removes contaminants.
NSF-International is a third-party entity that develops standards for clean water, food and consumer products. Their mission: “to protect and improve global human health.”
NSF-International is a third-party entity that develops standards for clean water, food and consumer products. Their mission: “to protect and improve global human health. Manufacturers, regulators and consumers look to the NSF to develop public health standards and certifications that help protect food, water, consumer products and the environment.”
Products are rigorously tested in their own labs, according to set standards, and certify only products proven to do what they claim. NSF certifications are given for individual standards. The first NSF standard for drinking water was set in 1973.
Here are the top 6 filtration standards used by the NSF when certifying drinking water systems:
- NSF Standard 42: Aesthetic Effects
– Reduces non-health related contaminants – Chlorine, taste, odor, and particulates that might be in your drinking water.
- NSF Standard 53: Health Effects
– Reduces specific health-related contaminants – cryptosporidium, giardia, lead, and volatile organic chemicals (VOCs).
- NSF Standard 58: Reverse Osmosis
– Reduces contaminants that can be removed through reverse osmosis filtration – hexavalent chromium, cyst reduction, arsenic, and nitrates/nitrites.
- NSF Standard 401: Emerging Compounds/Incidental Contaminants
– When a water filtration system removes up to 15 individual contaminants such as prescription drugs, over the counter medications like ibuprofen and Naproxen, herbicides and pesticides, as well as other chemical compounds like BPA.
- NSF Standard P473: PFOA/PFOS
– NSF was the first to develop a standard for the reduction of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate – chemicals used to make non-stick cookware. Aquasana filters were the first to earn certification under this standard.
- NSF Standard P231: Microbiological Filtration
– Reduces microbial contaminants like viruses and bacteria.
Aquasana’s NSF Mark
While many companies are content with a Standard 42 Certification (Chlorine, taste, and odor) for drinking filters and systems, Aquasana wants our customers to know that our products are obsessively engineered to remove not only what can be seen and tasted, but also the harmful contaminants that have no taste, smell or odor.
Aquasana is determined to test its products far beyond what’s needed to put that little blue circle on the label. Currently, the Reverse Osmosis system is NSF certified to remove over 79 harmful contaminants including Chromium-6, earning it a feature on the Today Show. The 3 Stage Under-Counter system, Clean Water Machine, and our Countertop Water Filter are all certified to remove up to 77 contaminants. Aquasana was the FIRST to have drinking systems that are certified to remove PFOA and PFOS – Check it out!
The NSF explains these chemicals for you: “PFOA and PFOS are fluorinated organic chemicals that are part of a larger group of chemicals referred to as perfluoroalkyl substances (PFASs). They have been used to manufacture carpets, clothing, cookware, fabrics for furniture and paper packaging that are resistant to water, grease or stains. They are also used for firefighting at airports and in a number of industrial processes.”
Aquasana is proud to be leading the charge against this imminent danger to US drinking water. “We want to prove that our products remove the most contaminants…ours are the best on the market.” explains Aquasana Vice President of Manufacturing, Wes Russell. “Our goal is to be certified in as many areas as possible.”

This isn’t the first time we’ve responded to a municipal water threat. “About three years ago, pharmaceuticals were found in the drinking water in the City of New Jersey,” recalls Russel. “We were aware of the issue immediately and were one of the first companies to have our product tested for pharmaceutical removal.”
Today traces of pharmaceuticals have been found in drinking water across several states, making our NSF/ANSI 401 (Drinking Water Treatment Units-Emerging Compounds/Incidental Contaminants) certification all the more desirable.
Aquasana will continue to lead the industry by engineering and certifying products that meet the NSFs rigorous certification standards. We will be on guard against whatever pollutants and contaminants are threatening our water, and continue to be the best solution to an aging water infrastructure.
