    摘要: The invention relates to liners for air ducts. Specifically, the invention is an article comprising a porous polymeric membrane layer and, optionally, a support layer, in which the article is a duct liner adapted to be removably positioned within a porous air duct. The liner may also be used in conventional metal and plastic ducts to reduce cleaning frequency. In another aspect, the invention is a porous air duct comprising: a liner comprising a porous polymeric membrane and, optionally, a support layer; and an openwork conduit, said liner disposed within the openwork conduit.
