A device for cleaning air laden with CO2 present in an enclosed space, including at least one adsorption device for adsorbing CO2 from the air supplied to the adsorption device, a desorption device associated with the adsorption device for desorbing adsorbed CO2, and a removal device for removing the desorbed CO2.

A filter cover structure of a drawer-type air cleaner is provided. The structure includes a main body in which an air filter reception part is formed and a filter cover provided to open or close the air filter reception part. The filter cover includes a lever configured to be locked to or released from a filter cover fastening part of the air filter reception part by rotating the lever around a rotating shaft.

A cabin air filter is provided with a filter medium and a filter element frame that frames the filter medium and is configured to attach the cabin air filter to a filter housing. The filter element frame is provided with at least one engagement element configured to engage pivotably at least one receiving element of the filter housing for pivoting the cabin air filter relative to the filter housing about a pivot axis. The filter element frame also has at least one snap hook that locks with at least one locking element of the filter housing for blocking pivoting of the cabin air filter relative to the filter housing at least in a first direction about the pivot axis.

An air box and methods are provided for communicating an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The air box generally transports air received by way of air inlet ports that mate with aerodynamic elements of the vehicle. The air is received through a conduit to an air intake duct of the engine. The air box an enclosure that is formed in a substantially rigid/solid form. A substantially transparent inspection region is disposed on a surface of the enclosure so that the air filter may be viewed and potentially accessed if desired.

An air filter for a ventilation device of a motor vehicle is disclosed. The air filter has a planar extension along which the air filter is able to be inserted into a flow area of the ventilation device transversely relative to a flow direction and has a filter medium arranged along its planar extension. The filter medium is bordered at least in certain regions by at least one frame wall. The frame wall has at least one section which is able to be brought into engagement with guide elements of the ventilation device in order to guide the air filter during insertion into the flow area. The section is a notch on an edge of the frame wall and is formed with an undercut relative to the edge such that the air filter is able to be braced transversely relative to the insertion direction during insertion in two directions.

The air box comprises an enclosure that is formed in a substantially rigid/solid form. A substantially transparent inspection region is disposed on a surface of the enclosure so that the air filter may be viewed and potentially accessed if desired.

A vehicle air-conditioning apparatus includes a case including an air passage therein and a filter arrangement area provided in the air passage for arranging a filter. The case includes: a drain port provided on a bottom portion of a downstream-side air passage in the filter arrangement area; an insertion port provided on a side surface of the case and configured to allow insertion of the filter into the filter arrangement area; a water receiving portion provided on a bottom portion of an upstream air passage in the filter arrangement area; a drain channel passing below the filter arrangement area and configured to introduce water from the water receiving portion to the drain port; and a waterproof wall that covers a lower corner portion on the insertion port side of an upstream-side boundary of the filter arrangement areas. The waterproof wall is increased in height toward the insertion port.

A climate control system includes a cabin air filter and a blower assembly having a motor and a fan rotated by the motor. The fan is configured to circulate air through the cabin air filter when the motor is energized. A controller is programmed to issue a message to change the cabin air filter in response to a revolution count of the motor exceeding a predefined threshold.

A conditioning device for a ventilation intake, the conditioning device having a frame with a mounting side, an access side, and a plurality of walls coupled between the mounting side and the access side. The mounting side defines a ventilation intake opening that is configured to receive at least a portion of the ventilation intake. The access side defines an access opening. An access panel has coupling features for removably coupling the access panel to the frame, where the access opening of the frame is accessible when the access panel is removed from the frame. The conditioning device is configured to cover the ventilation intake. At least one inlet is defined within at least one of the frame and the access panel and air enters the conditioning device through the at least one inlet.
