The micron ratings shown at various efficiency and beta ratio value levels were determined hrough laboratory testing, and can be used as a guide for selecting cartridges and estimating their performance.

Under actual field conditions, results may vary somewhat from the values shown due to the variability of filtration parameters. Testing was conducted using the single-pass test method, water at 3 gpm/10” cartridge.

Contaminants included latex beads, coarse and fine test dust. Removal efficiencies were determined using dual laser source particle counters.
