1. A method comprising:
monitoring, by at least one processor disposed in a housing of a medical imaging system, an air filter operating condition, wherein the housing comprises at least one air inlet and at least one air outlet;
determining, by the at least one processor, that the air filter operating condition is not within a pre-determined threshold;
providing, by the at least one processor, a control signal to at least one air filter, wherein the at least one air filter comprises:
a motor configured to activate in response to the control signal;
a drive shaft rotatably coupled to the motor;
a rotatable passive shaft;
a continuous belt air filter coupled to the drive shaft and the passive shaft; and
a stationary filter brush mounted against the continuous belt air filter; and
rotating, by the motor in response to the control signal, the drive shaft to translate the continuous belt air filter around and between the drive shaft and the rotatable passive shaft, and across the stationary filter brush.
