1. A vehicle air handling system comprising:

  • a housing including an outlet configured to guide air flow to a passenger compartment, a fresh air inlet configured to provide air from outside the vehicle into the housing and a recirculated air inlet configured to guide air flow from the passenger compartment into the housing;

    a blower arranged to move air through the housing from the fresh air inlet and the recirculated air inlet to the outlet;

    a sensor positioned to obtain humidity and temperature values for the air flow through the outlet;

    an air intake valve mechanism configured to move between a closed position blocking air flow from the fresh air inlet into the housing and an open position unblocking air flow from the fresh air inlet into the housing; and

    a controller operably coupled to the air intake valve mechanism to selectively position the air intake valve mechanism relative to the fresh air inlet to control an amount of fresh air introduced into the housing in order to maintain moisture density of the air flow entering the passenger compartment within a prescribed range based on the humidity and temperature measurements from the sensor.
