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.

These elements are bagged dried before shipping.

Internal diameter unless specified OD (outside diameter).

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.
