A germ-repellent plastic for use in a gas pathway of a respiratory device contains an anti-biofouling compound, and a basic plastic. The anti-biofouling compound is optionally selected from the group of a polyol, a polyether polyol, a polyol derivative, and a combination thereof; or the anti-biofouling compound is selected from the group consisting of a polyether, a poly(ethylene glycol) ether, a polysorbate, and a combination thereof; or the anti-biofouling compound is selected from the group consisting of poly(ethylene glycol) sorbitan monolaurate, poly(ethylene glycol) sorbitan monooleate, poly(ethylene glycol) sorbitol hexaoleate, ceteareth, and a combination thereof. The basic plastic is selected from the group of a blend of a low-density polyethylene polymer and an ethyl vinyl acetate copolymer, a blend of a polypropylene polymer and an ethyl vinyl acetate copolymer, a blend of polyolefin elastomer polymers and a polyvinyl chloride polymer. A method for manufacturing such a germ-repellent plastic, a gas pathway component of a respiratory device containing the germ-repellent plastic, and a respiratory device are also described.
