Disclosed is a method for determining the life of a filter screen of an air purifier, including the following steps: measuring the dirt holding capacity M of a chosen filter screen of a purifier by a test, measuring the initial filtration efficiency η0 of the filter screen and the filtration efficiency η1 of the filter screen at the end of the service life of the filter screen, determining the airflow rate Q of the purifier in operation, calculating the amount of dirt collected on the filter screen within a certain period of time, and when the amount of dirt collected on the filter screen exceeds the dirt holding capacity M of the filter screen, alerting a user to replace or clean the filter screen. L'invention concerne un procédé pour déterminer la durée de vie d'un tamis de filtre d'un purificateur d'air, comprenant les étapes suivantes : mesurer la capacité de retenue de saleté M d'un tamis de filtre d'un purificateur choisi par un test, mesurer l'efficacité de filtration initiale η0 du tamis de filtre et
