  • the shape of the mesh filter 13 is maintained by a support member 13a.
  • the support member 13a may be omitted as long as the mesh filter 13 has the strength large enough to maintain the shape thereof.
  • a part of the airflow passing through the filter 5a flows through the humidifying body 6 while the remaining part of the airflow flows around the humidifying body 6. Then, the airflow passes through the fan 4 and is discharged to the outside of the body case 1 through the airflow discharge portion 3.
