摘要： The present application discloses an electric breathing apparatus and an air filter device for the same. The air filter device comprises a blower unit including a housing; and an air filter unit removably connectable to the blower unit. The housing includes an interface configured to face towards the air filter unit when the blower unit and the air filter unit are connected to each other. A casing of the air filter unit includes a filter mesh side configured to face towards the blower unit when the blower unit and the air filter unit are connected to each other. The housing of the blower unit includes a first subset of Hall sensors at the interface. The first subset of Hall sensors includes N Hall sensors spaced from each other, wherein the N is an integer equal to or greater than 2. The casing of the air filter unit includes N alignment positions at the filter mesh side. When the air filter unit is connected to the housing of the blower unit, the N alignment positions are aligned with the N Hall sensors respectively. The air filter unit includes one or N magnetic counterparts selectively located at the N alignment positions. The one or N magnetic counterparts are arranged in a manner corresponding to an operating mode of the blower unit with respect to the air filter unit.
