Abstract: A device for facilitating removal of a filter from an air circulation system includes a flexible element having a first, low profile position adjacent a surface of the filter and a second, extended position spaced from the surface of the filter. When in the extended position the flexible element provides a graspable or grippable medium for removing the filter from the air circulation system. The device also includes attaching means for securing the flexible element to the filter.

Abstract: Nonwoven webs having substantially aligned fibers can be formed in an apparatus having a direction of motion corresponding to the direction of web formation. The web is formed in the presence of at least one secondary fluid stream that oscillates the filaments or resulting attenuated fibers to and fro generally in and against the direction of motion so that a majority of the collected fibers are aligned within ±20° of the direction of motion and fibers having lengths of about 1 - 10 cm can be teased from the web. The resulting nonwoven webs are especially useful for forming pleated filtration media having pleats generally transverse to the direction of motion.
