Abstract
An air cleaner capable of removing bacteria and viruses. The air cleaner includes: a main body including a suction hole through which air is introduced and a discharge hole through which air is discharged; an ultraviolet (UV) irradiation device disposed between the suction hole and the discharge hole, and including a UV light emitting diode (LED) configured to transmit ultraviolet rays toward the discharge hole; a photocatalyst filter including a photocatalyst provided to generate active oxygen by reacting with the UV rays transmitted from the UV LED, and disposed between the UV irradiation device and the discharge hole; and a light blocking member disposed between the UV LED and the suction hole to prevent the UV rays transmitted from the UV LED from being emitted to an outside of the main body through the suction hole.
