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 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.

An electro-ionic device configured for being worn on the face of a person is disclosed. The electro-ionic device includes at least two electrical conductors spaced apart from each other defining at least a portion of a respiratory pathway therebetween and a circuit configured to apply a first voltage between the two conductors during inspiration and a second voltage greater than the first voltage during expiration.

The field of this invention is technology that supports and enhances natural face-to-face communication. Throughout the recent Pandemic, people have been adversely affected by the loss of real face-to-face human contact. The invention provides one or more safe ‘meeting spaces’ through which persons can talk to each other normally, without the risk of airborne pathogens passing between them. The meeting space of the invention offers no physical barrier such as glass, which would reduce the quality of communication and diminish the user experience. Persons may see and hear each other through the meeting space but pathogens cannot substantially pass through it. Various ways are provided that substantially destroy/inactivate/remove pathogens from the meeting space(s). Some embodiments are sustainable, carbon neutral and solar powered. Others are highly energy efficient. Further refinements create a pleasant environment for conversation and enhance the user experience.

A filter unit for an air cleaning device includes an odor filter configured for odor neutralization and embodied as a device for plasma generation. The odor filter includes an air-permeable high-voltage electrode and an air-permeable counter electrode arranged behind one another in a direction of flow of air. Each of the air-permeable high-voltage electrode and the air-permeable counter electrode is formed by a panel element.

A system including tubing and a filter configured to be fluidly coupled to a vacuum source and to a heater/cooler unit by the tubing. The filter includes a filter container having negative air pressure in the filter container provided by the vacuum source to pull aerosol from the heater/cooler unit into the filter container and eliminate and/or reduce the aerosol emitted from the heater/cooler unit.
