A structure for attaching a blocking member displaces the blocking member from an insertion position where clamping pawl parts are arranged in a notch part to a fixation position where an opening edge portion is clamped in clearances between the clamping pawl parts and a main body part of the blocking member, thereby to attach the blocking member to an attachment object member. A projecting part that projects toward the blocking member is formed around an opening. At least a part of the projecting part is a side surface projecting part that projects along an outer peripheral side of a side surface of the blocking member when the blocking member is displaced to the fixation position. At least one of the clamping pawl parts is a low-load clamping pawl part. A clearance size between the low-load clamping pawl part and a main body part of the blocking member is provided to be larger than a clearance size between another clamping pawl part and the main body part of the blocking member.

The frame has a front wall extending perpendicularly to an insertion direction in which the filter element is insertable in a receiving space of a housing of the air filter device. A securing element is disposed on a front side of the front wall on which securing element a cover of the air filter device configured for closing the receiving space is fixable. The securing element has two holding parts which are engageable with two corresponding holding parts of the cover. The two holding parts of the securing element are configured as wings projecting from a shank of the securing element transversely to the insertion direction and the two holding parts extending from a respective first end region to a respective second end region, facing the front wall, are ramp-shaped.

An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) system air filter for a building ventilation system. The HVAC system air filter comprises a supportive frame configured to orient the HVAC system air filter within the building ventilation system. A composite filter medium retained within the supportive frame comprises a cotton gauze portion and an electrostatic portion. The cotton gauze portion is configured for treatment with a filter oil composition to enhance airflow and filtration of air flowing through the composite filter medium. The electrostatic portion is configured to electrostatically attract and agglomerate airborne molecular contaminants and volatile organic compounds (VOCs) as small as 0.001 microns in diameter. In some embodiments, the composite filter medium comprises substances configured to release a fragrance into air passing through the composite filter medium.

An air purifier having a shape and structure suitable for application to a vehicle interior are disclosed where the air purifier for a vehicle, includes an exterior housing having an open outlet configured to discharge purified air, a blower fan configured to rotate inside the exterior housing, to suction air into the exterior housing, and to blow the purified air to the outlet, a filter configured to purify the air suctioned into the exterior housing a fan support configured to support the blower fan, fixe the blower fan to the exterior housing, and having a plurality of holes through which air purified by the filter moves to the blower fan, and a mesh cover fixed at a position in which the air is suctioned into the exterior housing, the mesh cover having a plurality of holes formed therein and having a filter mount on which the filter is mounted.

A filter element for a filter assembly includes a filter media, a main seal, and a planar side seal. The main seal is coupled to an outer periphery of the filter media and disposed in a main seal plane perpendicular to a first side wall of the filter element. The planar side seal is coupled to and extends outward from the first side wall, and diverges away from the main seal plane.

A filter element for an air filtration device of a motor vehicle includes a frame where the frame has an elastically deformable front wall which extends perpendicularly to an insertion direction of the filter element in a receiving chamber of a housing of the air filtration device. A fastening element is disposed on the frame where a lid of the air filtration device is fixable on the fastening element and where the lid is configured for closing the receiving chamber. An insertion bevel is formed on the frame wherein via the insertion bevel the front wall can be brought into an elastically deformed state during an insertion of the filter element into the receiving chamber. An inherently rigid component is mounted on the frame in an area of the front wall where the fastening element is formed integrally with the component and the component has the insertion bevel.

An air filter device for a motor vehicle includes a housing with a receiving space for a filter element where the filter element has a respective first projection that projects from each side wall near one of two transverse walls. The housing has two opposite housing side walls, both of which have at least one link each in which the first projection of the respective side wall of the filter element is insertable in a first link end region directed in a first direction. A respective second projection projects from the side walls near the other one of the two transverse walls and the housing side walls each have a second link end region directed opposite to the first direction into which the second projections are insertable such that the filter element is located in an operating position in the receiving space of the housing.
