ABSTRACT:
A vent assembly includes a vent cover which is detachably mounted to a damper housing. Couplers mounted to the damper housing each have a catch portion which is inserted into a respective air flow slot of the vent cover to engage the vent cover and couple these components together. The couplers may be constructed to permit flexing of the couplers during the insertion process, with the couplers being biased to engage the vent cover when no longer flexed. A filter housing may be detachably coupled to the damper housing to support a filter on the opposite side of the damper housing from the vent cover.
