Just curious why we are using aircrafts that APU is INOP.   We are jeopardizing the safety of our crew members and passengers for not using the HEPA filter when the aircraft is on the ground. Using the air hose isn't a solution either.  It's just blowing air around.  We should not be using the aircraft that APU is INOP.    I just had this incident when we had an aircraft APU in INOP.  Sorry for the last response.
Ground employee reported wanting to know why the airline is using aircraft that do not have a functioning Auxiliary Power Unit.
