Keeping units serviced with high-performance chemisorbant media is a very important part of system maintenance. If the media is not changed out when it is due for replacement, the unit will not function properly and unwanted gases will be released into the environment. The life span of media will vary depending on many factors, such as type and quantity of gas, airflow, etc., but on average it lasts for a little more than a year. There are multiple ways to test and see if the media is reaching its expiration date:
1. Media Bed Indicator – Most deep bed scrubbers have a silver indicator inserted into its bed. Pull out the indicator to see where the furthest end of the indicator is being corroded. When the corrosion travels past the middle of the indicator, it is time to replace the media and ensure the system’s proper functioning.

2. LIFEGARD™ Media Bed Monitor – The LIFEGARD™ offers enhanced continuous, real-time monitoring with an advanced electronic notification system that simplifies maintenance scheduling and enhances operational efficiency. Equipped with externally wired and mounted sensors, the monitor detects variations in chemisorbant media, enabling precise forecasting of media consumption.

3. Media Testing – Free media testing is offered to all PureAir® customers. This testing requires collecting two cups of media from the system. For deep bed scrubbers, we recommend extracting media from each media sample port (top, middle, and bottom). Place the media samples in sealable bags, label, and mail in for media life analysis. As soon as the media is received, it is tested and a lab report analyzing the lifetime value of the media is returned. Sample media testing for shown at right/below.

4. Corrosivity Test Kit – a test kit consists of a strip of silver and copper that is hung in the applicable room for 30 days. The test kit is then sent back to our in-house lab to determine which type of gases caused the corrosion, and in what quantities. From there, PureAir will recommend a solution to remove the appropriate gases from the room. PureAir’s Environment Corrosivity Monitor (ECMv2) offers live, accurate results and detection of corrosive gases in the environment without lab testing.
