The upstream layer provides an efficiency rating of 70% for 3 to 10 micrometers. The downstream odor removal layer is impregnated with carbon media for absorption of volatile organic compounds (VOC’s) from the air stream. This carbon media carries a minimum activation of 60%, insuring high odor absorption efficiency, and extended lifecycles between filter changes.
