Abstract: An air cleaner includes: a housing including a suction portion suctioning air and a discharge portion discharging air, a frame disposed inside the housing, a sterilizer sterilizing the suctioned air, a filter assembly filtering air, a blower moving air, a flow converter disposed on a top surface of the housing, guiding a flow of air, and discharging air inside the housing to an outside, and a guide guiding a direction of the flow converter. The sterilizer includes a sterilizing light source generating sterilizing light, a first sterilizing casing accommodating the sterilizing light source, and a second sterilizing casing coupled to a lower portion of the first sterilizing casing and supporting the first sterilizing casing and the sterilizing light source, where a portion of the first sterilizing casing is spaced apart from the second sterilizing casing to define a space therebetween that dissipates heat generated from the sterilizing light source.
