Abstract: An apparatus for purifying air, in particular for ventilation and air-conditioning systems, has an air filter (11), which is inserted in an air channel (10) or in a filter wall for collecting dust. A dust agglomerator (12) with a DC voltage field is connected directly upstream of the air filter (11). In conventional filters, the efficiency is increased to such an extent that the dust throughput can be approximately halved. In addition, the initial efficiency is only insignificantly reduced during the operating time.

Abstract: To permit environmentally safe incineration of a filter bag together with its holding frame, and without requiring removal of the holding frame prior to incineration, the holding frame is made of fibers or cellular pulp stock, and, in plan view, is essentially rectangular. It is formed of two folded walls which, before insertion of the folding bag, are in essentially V shape, with an outer wall (6) and an inner wall (7), the V defining a gap of between 25.degree. to 50.degree., preferably about 38.degree., between which gap the filter bag is inserted. The inner wall, at the corner, is formed with a wedge-shaped gusset (9), with folding creases (10, 11) and a crest crease (12) between the folding creases. After insertion of the filter bag, the inner wall (7) is pressed against the outer wall (6), and the gussets snapped against the inner wall, to hold the frame together. The inner surfaces of the inner and outer walls (7, 6) can be coated with an adhesive (28), for example a heat-responsive adhesive, for reliable adhesion of the filter bag, and the inner tip of the V can be reinforced by a reinforcing strand, rope, filament, tape or wire (26). The frame is made by forming the frame walls with extending flanges (17, 18), the inner wall, for example, being connected by a web (17). After the pulp has dried, and the frame is stable, the flanges and/or the web are trimmed off, and the waste or trim material can be recycled for further pulp stock, to make additional frames.
