Abstract

A nasal-plug filter device including a device body, a filter, a first actuator, a second actuator, and a gas sensor is provided. The device body has a ventilating channel, and the ventilating channel has an inlet end and an outlet end. The filter is disposed at the outlet end. The first actuator is disposed at the inlet end for being driven to transmit gas outside the device body into the device body. The second actuator is stacked on and bonded to the first actuator, and the second actuator is driven to transmit the gas transmitted by the first actuator to the filter to be filtered and purified. The gas sensor is disposed at the outlet end for detecting a gas quality of the gas at the outlet end. A connection element may be provided for connecting two nasal-plug filter devices with each other.
