The invention provides an air-conditioning filer screen cleaning prompt method and a device thereof, and relates to the field of air conditioner cleaning. According to the air-conditioning filter screen cleaning prompt device and the method, first ultrasonic wave emitted from an ultrasonic transmitter toward a filter screen is detected; second ultrasonic wave generated after the first ultrasonic wave is processed by the filter screen is detected; when the variation of the second ultrasonic wave relative to the first ultrasonic wave is within the preset first threshold range (it shows the dustaccumulation of the filter screen is relatively serious), cleaning prompt information is generated. Thereby, users are automatically prompted to timely clean dust on the filter screen in real time, the ventilation quantity will not be affected, the cooling and heating effects of the air conditioner are improved, and power consumption is reduced. Due to strong penetrating power of the ultrasonic wave, the detection result
