A lighting fixture is disclosed with effective disinfection properties against bacteria, fungi, and viruses. The fixture includes a fan to continuously draw air into the light fixture. The air drawn in is irradiated with UV radiation within the fixture, such as is provided from UV LED chips. The relatively small volume of the light fixture allows the flux or energy density of the UV radiation to be made more intense. After the air is sterilized, it can be put back into the room or building in which the fixture is placed. The white light provided by white light LEDs in the fixture provides illumination, and can further provide significant emission peaks at 405 nm and 470 nm which is also useful to pathogen inactivation.

The present disclosure relates to an antibacterial composition, a filter using the same, and a home appliance such as an air conditioner comprising the filter. More specifically, the antibacterial composition according to the present disclosure comprises a polymer resin, and an antibacterial additive composed of an antibacterial metal and an antibacterial metal oxide, and thus a filter manufactured therefrom has excellent antibacterial activity and also maintains antibacterial performance even if washed.

An air treatment device includes: a casing having an inlet through which air is drawn, and an outlet out of which the air drawn through the inlet is blown; a blade configured to adjust a direction of the air blown out of the outlet; and a generator configured to generate an antimicrobial element that sanitizes the blade. The blade has a first surface, and a second surface opposite to the first surface. The blade is shiftable between a first position in which the antimicrobial element is provided to the first surface and a second position in which the antimicrobial element is provided to the second surface.

A method of monitoring indoor environments for aerosolized pathogens includes: (a) receiving a pathogen status for each of a plurality of aerosol samples collected by a plurality of corresponding air treatment devices; (b) determining whether the pathogen status for each aerosol sample changes a safety status of a corresponding indoor environment from which the aerosol sample was collected; and (c) in response to determining a change in the safety status, generating a notification associated with the change in the safety status for the corresponding indoor environment.

An improved technology for inactivation of viruses, for example the SARS-CoV-2 virus that is causing the Covid-19 pandemic, is described. The technology can include a device that includes a substrate coated in a polymer that is infused with a pathogen inactivating material. In various embodiments, at a given time, a portion of the pathogen inactivating material is exposed to the environment, and the device is configured to periodically or intermittently expose additional pathogen inactivating material to the environment. For example, the polymer can be ablative or sacrificial.

A recyclable ceramic catalyst filter, a filtering system including the same, and a method of managing the filtering system are provided. The ceramic catalyst filter has a monolithic structure including a first surface which blocks a first material; and a second surface which removes a second material that passed through the first surface, where the second surface is activated and operates as a catalyst layer which removes the second material in response to energy supplied to the second surface.

An air purifying mask having a face mask along with components some of which are arranged inside a casing. The casing may contain an air filtering system, along with other associated components for the mask including blower, appropriate pressure, flow control and filtration settings, and heating control. A flexible attachable/detachable connecting coaxial duct for inhale and exhale, may connect the mask and the air filtration system. The system may have a heating element for self-cleaning and temperature control. The heating element may also help for disinfection of air path within the system and air mask.

A filter module for sterile filtration and virus filtration of fluid media. The filter module includes a filter membrane with a porous edge structure arranged thereon and at least one anchoring element. The filter membrane with the porous edge structure is embedded in the anchoring element and serves as edge reinforcement to improve the connection of the filter membrane to the anchoring element. The texturing or surface roughness of the edge reinforcement provides an interlocking effect between the filter membrane and the anchoring element. The embedding of the filter membrane in the anchoring element provides a fluid-tight connection of the membrane to the anchoring element which prevents the occurrence of leaks in the end region of the filter module. A method for producing the filter module is also described.

An indoor unit for an air conditioner including: a cabinet assembly forming an external appearance of the indoor unit and having a suction port formed in a rear surface of the cabinet; a filter module movably disposed in rear of the cabinet assembly; a filter module mounted to the filter mounting member and filtering foreign substances in air flowing into the suction port; a mobile member connected to the filter mounting member and moving a position of the filter mounting member; a driving device pressing the mobile member to change the position of the filter mounting member; and a controller configured to, in response to receiving a control command to change the position of the filter mounting member, operate the driving device that presses the mobile member.

The present invention relates to a sterilization device. The sterilization device, according to the present invention, comprises: a frame having a first surface into which air flows, and a second surface from which air flows out; one or more discharge electrodes disposed in the frame; and a plurality of ground electrodes alternately arranged with the discharge electrodes. The discharge electrodes each comprise: a framework extending in the direction parallel to the ground electrodes; a first discharge needle protruding toward the first surface from the framework; and a second discharge needle protruding toward the second surface from the framework. The discharge electrodes are inclined at a predetermined angle with respect to an arbitrary axis of rotation parallel to the direction in which the ground electrodes extend, such that a discharge treatment region is formed perpendicularly to a flow direction by means of the alternate arrangement of the discharge electrodes and the ground electrodes parallel to the flow direction. Accordingly, it is possible to sterilize all air passing through the sterilization device, and it is possible to design a compact sterilization device having a wide discharge treatment region within the frame.
