One or both is controlled (14), or else sensor information is interpreted, in dependence on activity status information received from a plurality of home appliances (16, 8, 20, 22). This enables the operational life time of components in system to be extended, specifically the sensors and/or air purifier filters. Alternatively or additionally, it enables the air quality sensor information to be interpreted more reliably. ## Claims ### Claim 1 An air processing system, comprising: a controller for controlling the air processing system, an air quality sensor having a sampling rate that relates to a frequency with which sensor readings are taken, wherein the controller comprises an input adapted to receive activity status information from a home appliance, and wherein the controller is arranged for: determining from the activity status information operational settings of the air processing system;
