Ozone-removal efficiencies of activated carbon filters after more than three years of continuous service.

Author(s) : WESCHLER C. J., SHIELDS H. C., NAIK D. V.

Summary

The paper evaluates the efficiency with which commercial charcoal filters remove ozone. Three different applications have been examined: a test plenum, an air handler providing outside air to a Class 100 clean room, and a plenum downstream of an air handler providing outside air to another Class 100 clean room. After 37 months, the charcoal in the test plenum has decreased in removal efficiency from 95 to 90%. After 37 months, the charcoal servicing the first clean room has decreased in efficiency from 85 to 60%. After 24 months, the charcoal servicing the second clean room is still removing 95% of the ozone in the airstream.
