1. An indoor unit in an air conditioner configured to condition air in an indoor space, the indoor unit comprising:
a casing that comprises an intake port opened downward toward the indoor space;
a fan configured to suck air in the indoor space into the casing via the intake port;
a first dust filter disposed adjacent to the intake port and that collects dust contained in the air sucked via the intake port;
a second dust filter that:
collects dust contained in the air sucked via the intake port at a position downstream of the first dust filter in an air flow direction, and
has a finer mesh than the first dust filter;
a light source configured to irradiate an upstream side of the first dust filter in the air flow direction with ultraviolet rays and disposed at a position where the light source does not overlap either of the intake port and the first dust filter when viewed along the air flow direction; and
a shield configured to block the ultraviolet rays from the light source toward the intake port, wherein
the first dust filter has a first surface having a planar surface as an upstream surface in the air flow direction, and
the light source irradiates the first surface with the ultraviolet rays.
