Abstract
A method for notifying a service life of a filter includes steps of providing a filter for filtering an air pollution source; providing a gas detection device for detecting the air pollution source and outputting the detection data of the air pollution source; providing a connection device for receiving, computing and comparing the detection data of the air pollution source detected by the gas detection device, so as to display a reducing rate of filtering efficiency for the filter; and when the reducing rate of filtering efficiency for the filter reaches a preset alert value, the connection device sends out a notification alert of replacing the filter.
