Trying to work on the smell in my car when it rains. Are there 2 or 3 filters? 1 - cabin air filter inside floor board. 2. - bioweapon filter that is against the firewall, behind and in under the 12v battery. 3?? The large hepa right behind the frunk ?

• A/C desiccant bag replacement every 3 years.
