The present invention relates to a system (40) for air filter management, the system comprising a plurality of air filter devices (41a,b) and an air filter control station (42). Each air filter device (41a,b) is provided at an air filter arrangement in an air flow inlet to an industrial installation and comprises at least one filter medium capable of removing particulate material and/or airborne molecular contamination, AMC, from an air flow received at the air flow inlet. Each air filter device comprises a set of sensors arranged to gather sensor data representative of an operating state of the air filter arrangement, a microprocessor and a communication unit. The air filter control station (42) comprises communication unit arranged to receive operating state information from the plurality of air filter devices and a user interface for selecting an air filter arrangement of an air filter device. The air filter control station also comprises processing circuitry arranged to estimate a life expectancy of the selected air filter arrangement based on the operating state information received from an air filter device provided at the selected air filter arrangement and on operating state information received from one or more other air filter devices provided at other filter arrangements.
