Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow-establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicle, with or without using flow-establishing devices.

An air filter including: a housing provided with an inner cavity, and an air inlet and an air outlet communicated with the inner cavity respectively; a filtration module provided in the inner cavity and located between the air inlet and the air outlet, and configured to filter the harmful substances; a fan provided in the inner cavity and located between the air inlet and the air outlet; a first detector configured to detect a first content of the harmful substances in the air in the production workshop; and a controller configured to control start, stop and rotational speed of the fan according to the first content. The air filter according to the embodiments of the present disclosure can realize intelligent and automatic filtration of the air in the production workshop, improve filtration efficiency and reduce energy consumption.

A grid cover for a grid of a filter system covers a strut of the grid. The grid cover may be removable. The grid cover may be configured as a clip and may be clipped on the strut of the grid.

An ambient air purification device for a road vehicle for removing dust, particulate matter, and/or gases from ambient air has one or more filter elements. The ambient air purification device is attachable in an external region to a vehicle rear of the road vehicle by a releasable coupling. The ambient air purification device has at least one mating coupling of the releasable coupling, wherein the at least one mating coupling is coupled to a vehicle-side coupling component of the releasable coupling. A road vehicle provided with such an ambient air purification device is provided.

An environmental air cleaning device for a road vehicle removes dust, particulate matter, and/or gases from environmental air. The environmental air cleaning device has one or more filter elements. The environmental air cleaning device is provided with a mounting device that rigidly couples to a vehicle-side mounting device for roof loads. A road vehicle with such an environmental air cleaning device is provided.

A filter assembly includes a support fame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.

A door and door closure system for an air filter cabinet are described herein. One device includes a magnet recess, a magnet coupled to the magnet recess and configured to engage with a magnet recess of a frame of an air filter cabinet and automatically align the door with the frame of the air filter cabinet when engaged with the magnet recess of the frame, and a handle adjacent the magnet recess of the door.

An air filtering assembly for particulate removal includes a housing that defines an interior space. An aperture is positioned in a front of the housing and is configured to allow flow of air into the interior space. An opening is positioned in a back of the housing and is configured to allow flow of air from the interior space. A slot is positioned in a top of the housing. A filter is selectively insertable into the interior space through the slot. The filter is configured to remove particulates from the air that flows through the interior space from the front to the back.

Filters for semiconductor tool and clean room applications to control airborne molecular contamination. The filter cartridge system includes a filter cartridge having a non-woven fiber and at least one adsorbent. In some embodiments, the filter cartridge is constructed of substantially combustible materials to support its end of service destruction.

A filter apparatus and method having a test port member in combination with a filter media. The test port member may be positioned adjacent the outer periphery of the outer peripheral frame and may be attached to a truncated portion of the filter media. One or more scrim layers may be disposed across one or more sides of the test port member and/or the truncated portion of the filter media. A plug may be inserted into a through port of the test port member.
