An improved air filter assembly for removing particulates and undesirable gases from a stream of contaminated air including a first layer of filter fabric formed by parallel elongated semi-cylindrical surfaces joined at common parallel edges and a cooperating second layer of filter fabric contacting the first layer of fabric at its common parallel edges so as to leave elongated parallel semi-cylindrical voids therebetween. The voids are filled with gas sorbing materials.
