Abstract: The invention relates to a filter module (1) for removing air-polluting materials from machine exhaust, comprising a filter housing (2) with an intake opening (5) and an outlet opening (6) for channeling machine exhaust through, at least one mounting element (24) for mounting the filter module (1) on a machine, and a filter assembly (7), arranged in the filter housing (2) and comprised of at least two filter groups (8), arranged in tandem in the direction of flow (3) and comprised of rod-shaped filter elements (10) with a filter medium (20), said elements being arranged parallel to one another at a constant center-to-center distance (9) and with their longitudinal axis largely crosswise to the direction of flow (3), wherein the filter elements (10) of two adjacent filter groups (8) are parallel to one another, and are arranged offset in relation to one another, crosswise to their longitudinal axes and to the direction of flow (3).

Abstract: A fan filter device with one or more fan blades substantially comprising a filter media coated or impregnated with a fluid for removing particulates, such as dust and other pollution, from airflow in a wide variety of environments. The fluid has evaporation and viscosity characteristics suitable for maintaining the filter media in a wet condition at the desired speed and temperature of operation.

Abstract: A method and apparatus for wet filtering machine exhaust with a desirable scented oil mixture is disclosed. Preferably, the machine exhaust filtered is the exhaust from office machines, such as printers, photocopiers, and facsimile machines, which expel ozone, particulate matter, and toner pollution into the ambient air.
