Infectious diseases can be transmitted to humans, or between humans and animals, by airborne viruses and bacteria, known as infectious aerosols. Current protective measures that individuals can take to avoid inhaling such aerosols are either marginally effective (personal face masks) or impractical (self-contained breathing apparatuses). Building ventilation systems employing high-efficiency filters to prevent distribution of such aerosols suffer from high energy costs and high filter replacement costs. The development of conventional, intramuscularly administered vaccines takes months or years to produce enough doses to protect a population from a rapidly spreading infectious disease. Airborne viruses and bacteria have been shown to be completely inactivated when exposed to non-thermal plasmas. Results indicate the potential for sub-lethal exposures of airborne pathogens could render them unable to spark an infection in a host, but still retain the necessary surface proteins to cause an immune response in the host.

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 a portable air purifier. In the portable air purifier, a fan base is disposed between a fan module including a mixed flow fan and a filter, and forms a passage that connects between the filter and the fan module while coupling the filter and the fan module. Accordingly, the portable air purifier can ensure improvement in air purification performance with no increase in the size of the portable air purifier.

Disclosed are a method for sterilizing an air conditioner, an air conditioner and a storage medium. The method includes receiving a sterilization instruction, and detecting a temperature of an indoor heat exchanger in a heating mode. When it is determined that the detected temperature of the indoor heat exchanger is lower than a preset sterilization temperature, according to the method, an enhanced vapor injection circulation is started to increase the temperature of the indoor heat exchanger to be higher than the preset sterilization temperature.

The present invention provides an air purifier which includes an outer case (10) having a filtering cavity (15) and a driving cavity (16) space apart from each other, a filter (20) received in the filtering cavity (15), a driving fan (30) received in the driving cavity (16). The outer case has at least one air inlet (17) and an air output arrangement (11). The air purifier further includes an air hub (40) provided between the filtering cavity (15) and the driving cavity (16). The air hub (40) includes a first air drawing frame (41) and a second air drawing frame (42). The first air drawing frame (41) extending within a central cavity (21) of the filter (20) and is coaxially formed with respect to the filter (20). An axial direction of the first air drawing frame (41) is aligned with a longitudinal axis of the driving fan (30). The second air drawing frame (42) peripherally, upwardly and radially extends from the first air drawing frame (41) toward an upper end of the filter (20). The first air drawing frame (41) and a second air drawing frame (42) increase total surface area for air flow and reduces air resistance and noise.
