A photocatalyst filtration system for a vehicle includes a housing having an airflow path, and a filter configured to filter air flowing in the airflow path, the filter having a first photocatalyst and a second photocatalyst. The system further includes a first ultraviolet (UV) light source disposed proximate the filter and configured to energize the first photocatalyst, and a second UV light source disposed proximate the filter and configured to produce light having a shorter wavelength than light produced by the first UV light source, and configured to energize the second photocatalyst. One of the first photocatalyst or the second photocatalyst is configured to remove odor from the air. The other of the first photocatalyst or the second photocatalyst is configured to remove bacteria from the air.

Photocatalytic filtration in vehicle HVAC system

Disclosed is an HVAC system configured to reduce noise. The HVAC system includes a door having a first and second end. The door includes an elastomer along the first end and a rotatable member adjacent the second end. The elastomer includes a door touch area. The case defines an internal case portion, external case portion, and a case opening fluidly connecting the internal and external case portion. The case is configured to receive the rotatable member of the door such that the door is rotatable about an axis between a first position, where the door covers the case opening, and a second position, where the door does not cover the case opening. The case includes a case touch area with a graining. The door touch area and the case touch area are substantially parallel and in contact along a surface contact area when the door is in the first position.

HVAC sealing surface with noise reduction configuration

An HVAC system includes a blower housing including a blower inlet and a blower outlet, the blower housing having a plastic skeleton structure. The HVAC system further includes a foam blower liner disposed within and coupled to the blower housing.
