Shur-Pak glass bead filter pack receives NSF 61 approval

October 5, 2020  By Ground Water Canada

Johnson Screens’ Shur-Pak glass bead filter pack line has received NSF/ANSI/CAN Standard 61 – Drinking Water System Components certification on bead sizes, 0.4 mm to 4.0 mm.

“Upgrading to NSF 61 certification was an important step,” said Craig Benson, Johnson Screens’ director of the water well global product line, in a press release. “Our customers who wanted to use our Shur-Pak glass bead filter pack needed NSF certification, so we made the investment to have Shur-Pak tested and certified to NSF-61.

The water-well industry uses NSF Certified products in the construction, completion and rehabilitation of a well. Shur-Pak glass bead filter pack is the appropriate choice for well that requires a filter pack, the company said.


Johnson Screens’ Shur-Pak glass beads are spherical and smooth, designed for optimum water circulation allowing exceptional filtration of suspended solids. The surface properties of the glass beads create superior self-cleaning that reduces bio-fouling and mineral scaling.

Johnson Screens manufactures industrial filters, architectural elements and water-well screens.
