A method for the dry filtration of a gas flow carrying foreign objects, a filter device for cleaning off waste gas resulting from additive manufacturing technologies, comprises feeding a raw gas flow containing foreign objects into a raw gas space of a filter unit having at least one filter surface separating a raw gas side from a clean gas side; feeding oxidant to a reaction region located on the raw gas side of the filter surface downstream of the filter surface; such that foreign objects contained in material cleaned off from the filter surface and/or in the raw gas flow react with the oxidant in the reaction region to form oxide-containing foreign objects.

The fog removal apparatus comprises a plurality of fog barriers for removing moisture in the fog by absorbing moisture in the fog and by allowing air to pass therethrough when the fog passes through the fog barrier on the wind, and a fog barrier support for supporting the fog barrier. The fog barrier comprises a perforated plate arranged on an outer surface of the frame to support the fog barrier; a coated mesh having a porous waterproofing function; a super absorbent sheet for absorbing a large amount of moisture from the fog passing through the fog barrier; a heating means arranged adjacent to the super absorbent sheet to heat and dry the coated mesh and the super absorbent sheet.

A particle filter assembly for a motor vehicle includes a particle filter, an exhaust-gas-conducting line which opens into the particle filter, and a secondary air supply. The secondary air supply is formed separately from the exhaust-gas-conducting line and fresh air is suppliable to the particle filter via the secondary air supply.
