Abstract: An electronic device includes a housing, a photocatalyst filter, at least one first sensor provided in the housing, a blower fan configured to introduce air into the housing, a light source configured to emit light to the photocatalyst filter, and a processor configured to control the blower fan and the light source, determine a degree of contamination of the photocatalyst filter based on a difference in sensor values between the at least one first sensor provided in the housing and at least one second sensor outside of the housing or a rate of change in sensor values between the at least one first sensor provided in the housing and the at least one second sensor outside the housing, and recycle the photocatalyst filter based on the determined degree of contamination of the photocatalyst filter.

Abstract: An air purifier and a method for controlling the same are provided. The air purifier includes a fan for suctioning air, an odor sensor for sensing a concentration of odor, a hybrid filter including activated carbon and a photocatalyst, and a light emitting diode (LED) arranged in an area where the photocatalyst included in the hybrid filter is positioned and emitting light. Identification is made as to whether the concentration of odor exceeds a first threshold value, the fan is driven to suction air to reduce the concentration of odor when the concentration of odor exceeds the first threshold value, and the LED emits light to the photocatalyst based on a concentration of carbon dioxide in the air if the sensed concentration of odor is not reduced to a second threshold value after a threshold time since driving of the fan.
