A vehicle cab duct arrangement allows an operator to gain access to two vents typically included in an air circulation system from a single opening for maintenance or replacement of filters. A fresh air vent communicates air into the housing from the outside environment and an interior vent recirculates air from the cab into the inlet plenum. Filters are received in both vents for removing impurities from the air passing into the inlet plenum. The fresh air vent has a removable grill that allows access to the filter, and the interior vent is spaced from the fresh air vent opening such that it is accessible from the opening so that the interior vent filter may also be removed for maintenance. The two vents are disposed parallel with respect to each other and the vehicle cab door, so that when the vehicle cab door is closed, air is forced inwardly through the interior vent and towards the filter on the fresh air vent to clean the filter.
