ABSTRACT:
An adsorption air filter has a self-supporting shaped structure of adsorber particles of regular or irregular form, which are joined to one another by binder particles also of regular or irregular form. The melting range of the binder particles is less than that of the adsorber particles, and the binder particles are smaller than the adsorber particles. The adsorber particles have an average size of 100 to 7000 .mu.m. The three-dimensional structure of the air filter has substantially repeating units of one adsorber particle and one binder particle, without the presence of agglomerates. The binder must not spread over the adsorber surface below 100.degree. C. In the production method, adsorber and binder particles are mixed with water and heated in a closed mold under pressure; the water is then driven off and the shaped element is allowed to cool.
