The ProGuard^® Media becomes spent over time and needs to be tested for remaining life. We offer that service to our customers who use our media free of charge. We supply sampling bags with a labels and instructions on how to take a sample. By periodically testing media-removal capacity, we can ensure performance to specification. We test all submissions and promptly mail our customers a report. We can perform emergency testing as necessary.

This graph is part of a lab report showing the remaining life of ProGuard^® filter media samples submitted for testing. The full report includes analysis of the type of media, observations of any abnormal conditions potentially affecting the media, and recommendations for change or replacement so that media maintains effective control of target contaminants.
