Abstract
The present disclosure relates to an air purifier. An air purifier according to an aspect of the present disclosure may include: a first body having an inlet and an outlet; a fan; a second body coupled to the first body, having a central portion located above the first body, and extending from the central portion in a direction crossing the up-and-down direction; a substrate; a light source disposed at the central portion or at a position corresponding to the central portion in the up-and-down direction; and a light guide facing the light source, and extending in a direction away from the central portion, so it is possible to minimize the number of the light sources and deliver light to an outside of the air purifier.
