Abstract
Systems and methods for use in a vehicle can involve determining that a plurality of closures of a vehicle have been closed, running an HVAC system in a fresh air mode after determining that the plurality of closures have been closed, and thereafter recirculating air while adding newly filtered air to maintain a positive air pressure level in a passenger cabin of the vehicle. The determining can occur after one or more people enter the vehicle and being driving, and the recirculating and adding can involve activating a recirculation mode and a fresh air mode simultaneously. Adding newly filtered air maintains a positive air pressure level in a passenger cabin, which level can be set based on an amount of leaks, a user setting, a vehicle type and a pollution level. The determining, running, and recirculating and adding can occur again after determining a vehicle closure has been opened.
