1. A nasal-plug filter device, comprising:
a device body having a ventilating channel, wherein the ventilating channel has an inlet end and an outlet end;
a filter disposed at the outlet end;
a first actuator disposed at the inlet end for being driven to transmit gas outside the device body into the device body with a relatively higher pressure;
a second actuator stacked on and bonded to the first actuator for being driven to retransmit the gas transmitted by the first actuator to the filter to be filtered and purified; and
a gas sensor disposed at the outlet end for detecting a gas quality of the gas at the outlet end.
