Certified Elements
NSF 61 Certified Drinking Water RO and NF Elements
The National Sanitation Foundation (NSF) provides
conformity assessment services in the area of public
health for the food preparation and plumbing water
industries. NSF is an organization accredited by the
American National Standard Institute (ANSI) to certify
products against several NSF/ANSI Standards, includ-
ing NSF Standard 61. NSF/ANSI Standard 61 is a test-
ing protocol that assures customers and regulators
that
products do not contribute to
unsafe levels of contaminants in drinking water.
AG and AK certified elements are selected when in-
comparable confidence is requested from drinking
water system components.
AG and AK certified elements feature a fiberglass out-
er wrap and standard feed spacers.

3 The element diameter (dimension C) is designed for optimum performance in GE
Water & Process Technologies pressure vessels. Other pressure vessel dimension
and tolerance may result in excessive bypass and loss of capacity.
