A detoxification device for removing pathogens from air within an environment. The detoxification device may include a filtration media for catching and retaining particles larger than about 0.3 micrometers (μm) with an efficiency of at least 99%. The detoxification device may also include a heating element having a metallic foam. The heating element may be heated upon application of an electrical current to the heating element. The heating element may, upon being heated, heat the filtration media to a target temperature that is effective to kill a pathogen.

The present disclosure relates to an energy-saving and environmentally friendly filter and a method for producing thereof. The energy-saving and environmentally friendly filter includes filter element body composed of a plurality of sections of bending parts, including a sealing part is arranged on the bending part and configured to block the bending part. The advantage of the present disclosure is that the large amount of air intake per unit time improves the combustion efficiency of the internal combustion engine fuel and makes the power more abundant.

An air cleaner for an internal combustion engine is disclosed. The air cleaner may include a housing defining an interior and having a first end and a second end opposite the first end. The housing may include an air inlet configured to be fluidly coupled to an air intake of the internal combustion engine and an air outlet configured to be fluidly coupled to a compressor of the internal combustion engine. The housing may include a general cylindrical shaped section extending from the first end and an inverse taper section located distally from the generally cylindrical shaped section and extending towards the second end. A diameter of the inverse taper section may increase from a first end towards the second end.

A vacuum cleaner includes a suction inlet, a suction source configured to generate an airflow through the suction inlet to draw debris with the airflow through the suction inlet, and a separator assembly. The separator assembly includes a housing having an air inlet and an air outlet, a debris collection chamber within the housing, and an inner chamber formed within a shroud that defines a cyclone axis and has a perforated portion. The inner chamber has a first end and a second end. The first end has a tangential inlet. The second end is open toward the debris collection chamber. An outflow passageway is outside of the shroud and in fluid communication with the air outlet and a filter is in fluid communication with the outflow passageway.

An air cleaner includes an intake filter seated on an air cleaner body, an air cleaner cover spaced apart from the intake filter and coupled to the air cleaner body, and a cover rigidity reinforcement member detachably coupled to the intake filter and configured to restrict displacement toward the intake filter. The intake filter includes a non-woven fabric configured to filter foreign matters of introduced outside air, and a filter frame surrounding and fixing a circumference of the non-woven fabric.

Air purifier systems for enclosed environments and processes for purifying air within the enclosed environments generally include four stages of filtration. The four stages of filtration include exposing the air to a carbon pre-filter followed by exposing the air to a particulate filter. The air is then fed through a photocatalytic filter and subsequently discharged back into the environment. The systems and processes deodorize, remove particulate matter and destroy airborne pathogens within the enclosed environment.

A pleated filter preparation system is provided for accurately counting pleats along a continuous sheet of pleated filter material and cutting the sheet into filter strips to be formed into filters. The pleated filter preparation system includes a pleat driver having multiple drive gears that engage with the pleats of the pleated filter material to move the pleated filter material through the system. A pleat counter counts peaks and valleys of each pleat comprising the pleated filter material so as to identify a target pleat to be cut. The pleat counter clamps and stretches the target pleat to distinguish the target pleat among the other pleats. A punch cut station cuts the target pleat to form a filter strip having a desired number of pleats. A pleat compressor compresses the filter strips to a predetermined size and then ejects the filter strips into a suitable container or bin.

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.

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.

A soft frame filter element and a preparing method thereof. The soft frame filter element comprises a cylindrical filter element body, a soft lower frame and -a soft upper frame. The cylindrical filter element body has a lower edge and an upper edge, and a hollow structure is formed in the center of the cylindrical filter element body. The soft lower border wraps the lower edge. The soft upper border wraps the upper edge. Both the soft lower frame and the soft upper frame can be compressed to reduce the hollow structure, so as to reduce its volume, so that, more products can be placed in the same area, reducing the packaging cost and transporting cost.
