<P>PROBLEM TO BE SOLVED: To develop a gas-mask which is not stuffy, is excellent in the removing performance of toxic gases, and in addition, for which the replacing work of an adsorbent is easy in order to solve the problem that since a crushed active carbon is used for a conventional gas-mask, the fine powder of the active carbon adheres to the adsorbent housing section, and a pressure loss of the active carbon layer becomes larger, and in many cases, a user feels stuffy. <P>SOLUTION: For this gas-mask, a honey-combed active carbon, especially, a honey-combed active carbon carrying a chemical is used as the adsorbent for toxic gases. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
