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;
a gas sensor disposed at the outlet end for detecting a gas quality data of the gas at the outlet end; and
a driving module electrically connected to the first actuator, the second actuator, and the gas sensor, wherein the driving module has a microprocessor and a communication unit;
wherein the microprocessor is configured to drive the first actuator, the second actuator, and the gas sensor, and the microprocessor is configured to transmit the gas quality data obtained by the gas sensor to an external device through the communication unit.
