In an automobile heating, ventilation, and air conditioning unit, an air-purifying filter is slanted and arranged in an upstream air duct defined in a HVAC unit case, so that the upstream end of the filter is supported by an upper supporting portion fixedly connected to the unit case for supporting the evaporator core and so that the downstream end of the filter is located away from the lower end of the evaporator core. Foot vent ducts are partitioned and formed in the unit case, utilizing the dimensional difference between the evaporator and heater cores in both height and width dimensions. Temperature-adjustment ribs, slanted and inwardly extending from the inner periphery of the forward wall of the unit case above the heater core, are provided close to foot vent outlets, so that the foot vent outlets face to a space defined just downstream of the temperature-adjustment ribs.

1. An automobile heating, ventilation, and air conditioning unit, comprising:a heating, ventilation, and air conditioning unit case permitting flow of interior air; a blower fan unit having at least a blower fan for introducing air into said unit case; an evaporator core assembly having an evaporator core disposed in said unit case for taking heat from the air discharged from the blower fan to produce cool air; a heater core assembly having a heater core disposed in said unit case downstream of the evaporator core for adding heat to the cool air to produce warm air; a bypass air passage bypassing the heater core; an air mix door disposed between the evaporator core and the heater core for controlling a percentage of the cool air passing through said bypass air passage and the warm air produced by the heater core, depending on a degree of opening of said air mix door; said unit case defining an upstream air duct in said unit case upstream of the evaporator core for routing the air discharged from the blower fan toward the evaporator core; and an air-purifying filter slanted and arranged in the upstream air duct, so that an upstream end of said air-purifying filter is supported by an upper supporting portion fixedly connected to said unit case for supporting the evaporator core and so that a downstream end of said air-purifying filter is located away from a lower end of the evaporator core.
