An air purifying system may include at least two air purifiers configured to operate independently and a docking station to support the at least two air purifiers. The docking station may include a backbone extending in a vertical direction and at least two supports corresponding to and supporting the at least two air purifiers. At least one air purifier may have a display configured to operate according to a plurality of modes. When the air purifier having the display is docked on the docking station, the display may indicate overall operating information of the entire air purifying system. When the air purifier having the display is separated from the docking station, the display may indicate individual operating information of the air purifier having the display.

A filter, a manufacturing method for a filter, and an air conditioner are provided. The filter includes a casing (10), a transition tube (20), and a filter screen assembly (30). The filter screen assembly (30) is provided in the casing (10), fitted with and connected to an inner wall of the casing (10), the casing (10) is an integrally formed piece, and two axial ends of the casing (10) have neck sections (11), and two neck sections (11) are both fixedly connected to the transition tube (20).

A ventilation type air cleaner includes a housing having a central rotating shaft including a purification part, a washing part, and a sterilization part in a circumferential direction with respect to the central rotating shaft, a rotating unit installed to be rotatable about the central rotating shaft as a rotation center in the housing, a filter assembly detachably coupled to the rotating unit and configured to sequentially pass through the purification part, the washing part, and the sterilization part according to rotation of the rotating unit, an intake duct connected to the housing and configured to guide a flow of air introduced to the purification part, and an exhaust duct connected to the housing and configured to guide a flow of air discharged from the purification part.

An antimicrobial air treatment device and a method of its construction. The antimicrobial air treatment device comprises an antimicrobial metal nanoparticle mesh comprising a steel support mesh and a layer of copper nanoparticles disposed on the steel support mesh. The antimicrobial air treatment device may be in the form of a facemask or a component of a moving air filtration system such as an HVAC system, an automobile cabin air filtration system, and an air purifier. The antimicrobial air treatment device may contain one or more filtration layers of filtration medium. The method of constructing the antimicrobial air treatment device involves the preparation of the antimicrobial metal nanoparticle mesh by an electrodeposition technique.

A humidifier/dehumidifier device is disclosed herein. The humidifier and dehumidifier both, respectively, evaporate water from and condense water into a shared (same) water storage container. The device is fitted with an air intake and at least one air outtake. In embodiments of the technology, one or more of the air intakes receives air from outdoors. One or both of an indoor and/or the outdoor intake is used to receive air based on a determination that an indoor and outdoor humidity and temperature is most efficient to achieve a desired indoor humidity or temperature.

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 application provides a wall-mounted air purifier, including casing, a filter installed in the casing, and a fan installed in the casing. The casing is defined by an air inlet and an air outlet, and the air outlet is located at the position corresponding to the outlet of the fan. The filter is arranged between the air inlet and the fan, a photocatalytic module is installed in the casing, and the photocatalytic module is arranged between the air inlet and the fan. The wall-mounted air purifier provided in the present application filters and purifies the air by arranging a filter in the casing; and arranging a photocatalytic module in the casing to sterilize and disinfect the gas entering the air inlet and decompose harmful molecules in the gas for better purifying the air and improving the air purification capacity.
