The present invention relates generally to desiccant bags and filters for use in receiver/dryers or accumulator canisters of automotive air conditioning systems. More specifically, the present invention relates to a dual or single desiccant bag provided with a filter section such that the desiccant bag effectively combines two separate components, a desiccant bag and a filter, into a single article. Accordingly, the bag is adapted to contain adsorbent material therein to adsorb moisture, or undesirable substances, within the a/c systems of automobiles, trucks or other motor vehicles while the filter is adapted to keep particles, dirt, or dust from entering the orifice in the bight of a U-bend tube where oil pickup is provided for lubrication of the a/c system.
