Abstract
An air purifier capable of reducing time required for purification of a room without giving a feeling of discomfort to a human in the room is provided. During operation of an air purifier, air drawn from an inletinto a casingis purified by a purification deviceand the air is blown to the outside from an outlet. If a user of the air purifierselects a particular operation mode in which the user designates an air volume, a control deviceperforms air volume maintaining control. In the air volume maintaining control, with a volume of air blown out from the outletby the air blowing devicemaintained constant, a speed of the air is varied by an air guiding devicebased on a status of pollutant detection. Alternatively, the speed of the air is varied by the air guiding deviceand the volume of the air is varied by the air blowing device. Consequently, a dust removal efficiency can be enhanced without giving a feeling of being blown by air to a human in a room, enabling reduction of time required for purification of the room while maintaining user comfort.
