PURPOSE: A pneumatic filter for respiration using a ceramic honey comb carrier is provided to expand contact area with air and to facilitate additional insertion of functional adsorbents and desiccants in various forms into each cell of the honey comb. CONSTITUTION: A pneumatic filter for respiration using a ceramic honey comb carrier comprises housing(10), a spring(20), a cover plate(30), a first non-woven fabric(41), a second non-woven fabric(42), a third non-woven fabric(43), a fourth non-woven fabric(44), a first absorber(51), a second absorber, a honeycomb filter(60), a bottom plate(70), and a vent(80). The housing is composed of a housing cover and a housing body. The spring can close by compressing the housing cover. The cover plate evenly pressurizes inside the filter when the housing cover closes. The first non-woven fabric and the second non-woven fabric filter out dust of the compressed air. The first absorber separates and removes by attaching on surface of toxic gas.
