Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a filter performance measurement device capable of automatically measuring performance of a filter. SOLUTION: This filter performance measurement device is provided with an upstream side duct 1, a downstream side duct 2 communicated with the upstream side duct 1, an air flow feeding means 3 feeding air flow inside the upstream side duct 1 and the downstream side duct 2, a filter conveying means 5 automatically conveying a filter 4 between the upstream side duct 1 and the downstream side duct 2, measuring means 6, 7, 8 measuring at least one of a pressure loss inside the upstream side duct, that inside the downstream side duct, a particle amount inside the upstream side duct, and that inside the downstream side duct when the filter exists between the upstream side duct 1 and the downstream side duct 2.
