[Problem] To make it possible to estimate clogging of a filter using a method other than the measurement of fluid pressure. [Solution] This filter monitoring system 1 is characterized by having: a vibration information transmission device that is attached to a filter device 2, detects vibration of the filter accompanying operation of the filter device 2, and transmits same as vibration information; and a clogging estimation device that estimates the degree of clogging in the filter by detecting a decrease in the vibration value due to clogging of the filter. |
