In response to the discovery of the chemical chromium-6 in the drinking water of 218 million Americans, the water experts at Aquasana – an industry leader in high-performance water filtration systems for the home and on the go – encourage concerned families across the country to be proactive in protecting their health by filtering their water using an NSF-certified reverse osmosis (RO) system. NSF International is a global independent organization that develops standards, and tests and certifies products for the water, food, health sciences and consumer goods industries to minimize adverse health effects and protect the environment. Also known as hexavalent chromium, chromium-6 is the same cancer-causing heavy metal made famous in the movie Erin Brockovich. The Aquasana OptimH2O® Reverse Osmosis + Claryum® is NSF certified to remove over 97% of chromium-6 from drinking water.

A safety limit for chromium-6 in drinking water has not been established by the US Environmental Protection Agency (EPA), and like lead, exposure is potentially dangerous at any level, especially in children and pregnant women. Until more is known, the easiest and most immediate solution for safe drinking water and peace of mind is to use a water filter. However, not all filters will remove chromium-6. The only way to effectively remove the carcinogen is through reverse osmosis. The OptimH2O® uses innovative RO, carbon filtration and remineralization technology to remove more than 80 different contaminants – including over 97% of chromium-6 and 99% of lead; then puts back healthy minerals removed in the RO process like calcium, magnesium and potassium.

“Whether we’re talking about the concerning lead poisoning in Flint, Mich., PFOA (previously used in manufacturing of some non-stick cookware) or now chromium-6, this is a serious issue that has been building for years and affects the nation as a whole,” said Todd Bartee, the CEO of Aquasana and a trained environmental engineer specializing in water treatment. “As our water infrastructure continues to deteriorate, we’re going to see an increase in these types of water safety issues across the country. We want families to know that there are straight-forward and immediate steps they can take to be proactive in protecting their health, and the most effective way to improve their drinking water is by using an NSF-certified water filter.”

Aquasana’s other drinking water filters are NSF-certified to remove more than 99 percent of lead as well as 65 other contaminants – including asbestos, pharmaceuticals, chloramines, herbicides, pesticides, industrial solvents, volatile organic compounds (VOCs) and mercury – and are available in countertop and under sink options that make clean, healthy water accessible to everyone.
