Abstract

[Object] To provide a filter device which is to be installed in a flow path and capable of implementing a more simple and logical flow path structure, the flow path being supplied with a pressure selectively switched between a negative pressure and a positive pressure.[Solution] A negative pressure-side flow path 40 having a negative pressure-side filter 4 and a positive pressure-side flow path 50 having a positive pressure-side filter 5 are connected in parallel between a first port 20 and a second port 30, and a shuttle valve 7 is installed between the negative pressure-side flow path and the positive pressure-side flow path, and the first port, thus when a negative pressure is supplied to the first port, the first port is caused to communicate with the second port through the negative pressure-side flow path, and when a positive pressure is supplied to the first port, the first port is caused to communicate with the second port through the positive pressure-side flow path.
