The inlet filter cleans room air on the way in. The in-line filter guards the boundary between the machine and the wearer, catching bacteria and fine particulate in the airflow and, just as importantly, stopping anything travelling back down the tube toward the blower. That matters in three situations in particular: where a machine is shared between users in a clinical setting, where the wearer has a respiratory infection and the circuit would otherwise be contaminated, and where a machine is loaned, hired or sold on. It is also the cheapest way to protect an expensive device from the inside.
