The invention discloses a biochemical defense material which is composed of a rough filtration protection layer, a filter layer, an activated carbon layer, a spacing layer, an adsorption catalyst layer and a sterilization layer from top to bottom in sequence. The comprehensive filtering efficiency of the material is improved on the premise that the resistance of the material is not affected, and the filtering efficiency for particles with the particle size smaller than 0.3 [mu]m is improved. Meanwhile, the material has the effects of adsorbing gas and sterilizing, finally achieves the purpose of biochemical defense, and can be directly used for preparing an automobile cabin.
