An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

A vacuum cleaner, includes a dirty air inlet, a clean air outlet and an air channel arranged between the dirty air inlet and the clean air outlet. A vacuum generator is arranged inside the air channel. A first filter is arranged in the upper reach of the vacuum generator. A second filter is arranged in the upper reach of the first filter. The vacuum cleaner further comprises a state sensor. When in a second state, the first filter and the second filter are not combined, and the state sensor is not triggered. Missing mounting prevention detection of a main filter and a pre-filter can be realised at the same time by means of a micro-control switch, thereby saving on cost.

A filter element for an air filter device of a motor vehicle includes a frame which surrounds a filter material. 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.

A filter assembly includes a housing, a cover, and a filter element. The housing defines a pocket. The cover includes a bayonet sized to be received within the pocket. The bayonet defines an elongated opening. The filter element is sized to be received within the housing. The filter element includes a media pack and a filter shell coupled to the media pack. The filter shell includes a trunnion that is sized to be received within both the pocket and the elongated opening to interlock the cover and the filter element such that removal of the cover from the housing initiates removal of the filter element.

A filter frame for an air handling unit, an air handling unit, and a method of assembling a filter frame for an air handling unit. The filter frame (100) includes a holder (110) defining a cavity configured to receive a plurality of filter cells (201, 202; 201, 202, 203), and a removable lid (120) configured to secure the plurality of filter cells (201, 202; 201, 202, 203) in the cavity. The removable lid (120) can also include a biasing element (130) configured to urge the plurality of filter cells (201, 202; 201, 202, 203) together within the cavity, to assist with securing the plurality of filter cells (201, 202; 201, 202, 203) in the cavity.

A vacuum cleaner including a dirty air inlet, a fluid flow path extending from the dirty air inlet to a clean air outlet, a fluid flow motor positioned in the fluid flow path, and a filter assembly positioned in the fluid flow path. The filter assembly including a first cylindrical filter and a second cylindrical filter nested within and removable from the first cylindrical filter. An inner diameter of the first cylindrical filter is smaller than an outer diameter of the second cylindrical filter such that the second cylindrical filter is compressed in order to be nested within the first cylindrical filter.

The present invention provides a handheld smoke filter, the handheld smoke filter includes a housing, wherein one end of the housing is fixedly connected to a smoke spray inlet, the other end of the housing is fixedly connected to a bottom cover, the housing is provided inside with a filter element shell for filtering smoke, the filter element shell is provided with a first sponge layer, an activated carbon filter layer, a second sponge layer and an HEPA filter sequentially disposed from a filter element intake hole to a filter element exhaust hole. The handheld smoke filter of the present invention can use sponge, activated carbon and HEPA for multiple filtrations, so as to collect smoke sprayed from the mouth of a user more effectively, with better filtration effect and better air permeability.

A filter assembly, has: a housing defining an internal volume and an outlet fluidly connectable to an oil system; a filter cartridge removably received within the internal volume of the housing; and an inlet conduit defining an inlet fluidly connectable to the oil system, the inlet conduit being in fluid flow communication with the internal volume of the housing, the inlet conduit having: a wall circumscribing a main flow passage from the inlet to the internal volume, and a sedimentation pocket defined by the wall, the sedimentation pocket extending downwardly away from the main flow passage and in a direction having a component parallel to a direction of a gravity when the filter assembly is in use.

Port protection device particularly suited for an encapsulated filter unit. In certain embodiments, the protection device comprises a main body defining an internal region configured to receive a port or the like protruding from an encapsulated filter. In certain embodiments, the main body includes a slot that allows for easy removal of the protection device from the port or the like. A tube management system may be provided to receive and hold tubing. One suitable tube management system includes two spaced tangs that extend from the main body of the protection device and are configured to cooperatively receive and hold tubing between them.
