The ozone destruction filter eliminates ozone generated during testing. Table 1 lists the parts required for the ozone destruction filter. However, the ASOPOS panel (Assessment of Standard Operating Procedures for Ozonesondes) recommends the use of purified, ozone-free air instead of the destruction filter. Refer to the GAW report 201 for more information. See Performance Review Literature .
