ABSTRACT:
An air cleaner including an improved airflow path is provided according to the invention. The air cleaner includes a duct extending between an air inlet of the air cleaner and an air outlet, with the duct being configured to conduct an airflow. The duct includes a shaped input region located downstream of one or more air cleaning components and upstream of an impeller, a curved transition region downstream of the shaped input region, with the curved transition region transitioning the airflow from an air inlet orientation to an air outlet orientation, and an expansion output region downstream of the curved transition region, with the expansion output region allowing the airflow to expand. The air cleaner further includes the impeller located in the curved transition region of the air duct. The airflow is smoothly conducted from the air inlet to the air outlet by the duct.
