Abstract: Provided are a composition, a device, a filter, a method and the like, which convert toxic carbon monoxide and/or carbon dioxide in waste gas to formic acid without by-products at room temperature and at room pressure by using carbon monoxide dehydrogenase and formic acid dehydrogenase. The composition, the device, the filter, the method and the like enable the removal of carbon monoxide which is emitted in a great amount from industries such as petrochemical and steel industry and tobacco combustion, household cooking appliances, and various boiler combustion, through a cigarette filter, an air purifier, a household cooking appliance suction filter, a gas boiler, etc. Accordingly, the production method can be variously applied.
