Abstract: The present invention relates to an air filter arrangement (20) configured to fitin an air flow passage. The air filter arrangement comprises an air filter framework (21), at least one filter medium (22) capable of removing particulate material and/or airborne molecular contamination, AMC, from an air flow received at the air flow passage, and an air filter sensor device(24)that is provided in the air filter framework (21) and configured to determine an operating state of the air filter arrangement. The air filter sensor device (24) includes air flow determining means for determining an air velocity of the air flow at the air filter arrangement (20), wherein the air flow determining means comprises measuring means configured to determine dynamic pressure or a pressure pulse attributable to a vortex pattern induced in the air flow, and in that the air filter framework comprises a structural element (23) configured to induce said vortex pattern. The invention also relates to air filter sensor device and a system for air filter management comprising the air filter sensor device.
