Rainfresh CRB20 Cyst Removal Filter

Description

Absolute rated one micron filter media removes cyst sized particles for safe, cyst-free drinking
water

Pleated polypropylene filter media provides more surface area for longer filter life and
increased particle removal

FDA listed materials for use in potable water and liquid food applications

End caps, center tubes and media are thermally bonded as one integral component for added
strength and to provide superior end sealing

CRB20 Cyst Removal Filter is Independent Lab Validated
To verify the performance of CRB series cartridges Pace Analytical*, a highly respected independent
testing facility, was selected to conduct challenge tests to the NSF 53-2007 protocol for cysts
reduction. The NSF 53-2007 protocol consists of two side-by-side systems operating on a 10-minute on / 10-minute off cycle.
Polystyrene 3-micron beads were injected after the 8th cycle and at 25%, 50% and 75% reduction in flow rate.
