The invention provides a method for automatically reminding replacement of an automobile air conditioner filter element. The method comprises the following steps: calculating the voltage difference of a driving circuit of a blower before and after airflow passes through the automobile air conditioner filter element, wherein the voltage difference is named as a first voltage difference; and comparing the first voltage difference with a voltage difference threshold, and sending automobile air conditioner filter element replacement reminding information if the first voltage difference is greater than a voltage difference threshold. According to the method provided by the embodiment of the invention, the voltage difference of the driving circuit of the air conditioner blower before and after airflow passes through the automobile air conditioner filter element is calculated and automobile air conditioner filter element replacement reminding information is sent if the first voltage difference is greater than the voltage difference threshold, so that compared with the prior art, the method has the advantages that the automobile air conditioner filter element replacement reminding information can be sent under conditions of not increasing the cost and volume of an automobile air conditioner, and the sent automobile air conditioner filter element replacement reminding information is accurate and timely, therefore, the filtration effect of air in an automobile is ensured, and economic waste caused by replacing the air conditioner filter element uniformly according to time due to automobile air conditioner use frequency difference of users is avoided.
