The Model 3 doesn't come with Bioweapon Defense Mode as an option. We felt you deserve to have similar high quality filtered air that Model S/X owners get. Our new air filter media is the same as used in Intensive Care Units at a hospital. It also has activated charcoal to combat bad odors. We recommend changing the filters once a year or every 12k miles. This ensures clean, odor free air inside the cabin for the life of the vehicle.
