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.
