摘要: A filter assembly (10) for removing particulate matter from air forced therethrough comprises two pairs of oppositely charged woven electrostatic filtering material. Each pair of electrostatic filtering material comprises a positively charged and a negatively charged layer (22, 24, 28 and 30). An open cell foam layer (26) is disposed between the two pairs. Metal grids (20,32) enclose the filtering elements.

摘要: A filtering unit (10) has four filter holders (20) arranged in a rectangle around a blower (36). Each filter holder holds up to two filter elements (11). The blower draws air through the filter elements (11) and outputs filtered air through a vent (40). Refillable filter frames (16) are provided to allow the user to change the filter material (18). In one embodiment, glass chips are used as the filter material (18).

摘要: An adjustable filter uses an eight member frame construction to provide a wide range of filter sizes. A panel for encasing one or more layers of filtering materials within the frame is formed from a grid having a border which unevenly encompasses the crossbars of the panel in order to allow various sizes of panels to be formed without producing exposed barbs and without increasing the air resistance of the filter. An embodiment using an electric field is disclosed to enhance the filtering properties of the filter.
