The 3M Service Life Indicator can help provide added peace of mind as a complement to your current change-out schedule and, in some cases, replace your current practices.

Is the indicator appropriate for my environment?

Rather than implement a common change out schedule across all workers, the indicator allows cartridges used in appropriate environments to be changed based on individual work hours, exposure levels, breathing patterns and environmental conditions.

1) Perform exposure monitoring to quantify the organic vapor exposure levels in your work place. 

2) Enter the monitoring results in the 3M™ Select and Service Life Software. If the ESLI is not applicable as a primary method, it may still be used to complement your current cartridge change schedule.
