The average particle diameter of the pre-treating filter is between 1um and 10um. The average particle diameter of fine dust removing type filter is between 0.1um and 1um. The pre-treating filter is spunbonded non-woven fabric or melt-blown nonwoven fabric. The fine dust removing type filter is melt-blown nonwoven fabric. The deodorizing filter formed a support and a coating layer formed of hydrophilically treated inorganic particles. |
