Abstract
A filter bypass valve is disposed in parallel with an aircraft cabin air filtration system air filter. During normal operation, air is filtered through the air filter at an air flow that meets air flow requirements of the system. The bypass valve is designed to remain closed during normal use, and to open if the differential pressure across the air filter reaches a predetermined opening differential pressure to allow airflow to be partially or fully diverted around the air filter.
