![]() Especially, the damage is very serious for those with low immunity such as infants and the elderly. Recently, as the use of building materials and finishing materials increases, the air environment in human living space is getting worse. Air pollutants generated in the living environment are classified into particulate pollutants such as pollen, dust and fine dust, and gaseous pollutants such as volatile organic compounds (VOCs), odors and environmental hormones, and biological pollutants such as mold, bacteria and bacteria. The present invention relates to an activated carbon filter paper which does not easily drop powder of activated carbon, has excellent physical properties such as burst strength and tensile strength, and good air permeability.
