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.
We claim: 1. An aircraft cabin air filtration system comprising: an inlet configured to receive a flow of air from an airflow source; an outlet configured to exhaust the flow of air to the aircraft cabin; an air filter positioned between the inlet and the outlet, the air filter being fluidly coupled to the inlet and the outlet and configured to filter the flow of air, whereby a differential pressure is developed between the inlet and the outlet; and a bypass valve positioned between the inlet and the outlet and in parallel with the air filter, the bypas...
