The filter unit 120 may function to filter smoke moving through the communication unit 110. The filter unit 120 may include a plurality of subfilters 360. The plurality of sub-filters 360 may be provided to perform different functions.

The smoke can contain a variety of harmful substances harmful to the human body. Since harmful substances include particles of various sizes and properties, they are filtered through a plurality of sub-filters 360 performing different functions in various ways . One of these functions may be to filter particles by size.

The plurality of subfilters 360 may include a first filter 330, a second filter 340, and a third filter 350 according to an embodiment. The first filter 330 may be provided to filter harmful substances having a size larger than the first value.
