Smart multi-modal vehicular air filtering system and associated methods

A non-transitory computer-readable storage medium storing code comprising instructions configured to, when executed by at least one processor, cause the at least one processor to:

• detect at least one parameter of ambient air from outside of a vehicle comprising a filter management system, the filter management system comprising:
• a first filter element and a second filter element disposed in an exterior fresh air housing, wherein the exterior fresh air housing comprises an inlet and an outlet;
• a third filter element disposed in a cabin housing, wherein the cabin housing comprises at least one inlet, and the at least one inlet is a filtered inlet;
• a fluid channel arranged between the exterior fresh air housing and cabin housing, wherein the filtered inlet of the cabin housing is configured to receive air from the exterior fresh air housing through the fluid channel;
• and
• a first diverter disposed near the outlet of the exterior fresh air housing;
• detect at least one parameter of cabin air from inside of the vehicle;
• based on the detected at least one parameter of ambient air and/or the detected at least parameter of cabin air being course particles, control the first diverter to move to a first position that opens a first pathway from a gap between the first filter element and the second filter element, through the outlet and into the fluid channel, so that only ambient air that passed through the first filter element into the gap without passing through the second filter element is allowed to exit the outlet into the fluid channel;
• and
• based on the detected at least one parameter of ambient air and/or the detected at least parameter of cabin air being fine particles, control the first diverter to move to a second position that opens a second pathway from a space adjacent to the second filter element, through the outlet and into the fluid channel, while substantially blocking the first pathway between the gap and the fluid channel, so that only ambient air that passed through the first filter element and the second filter element into the space is allowed to exit the outlet into the fluid channel.
