Disclosed is a vehicle comprising a wheel with an associated air-cooled motor, and a ventilation path for passing outside air from outside the vehicle into the motor. An electrostatic device is disposed proximate to the ventilation path. When the electrostatic device is energized, particles or debris in the outside air are attracted toward or repelled from the electrostatic device, such that the particles or debris are removed from the outside air before the outside air enters the motor.

An air cleaner according to an embodiment of the present disclosure includes: a main body including a main fan configured to generate air flow, a discharge part through which air passing through the main fan is discharged, a wireless power transmitter disposed on one side, and a power supply connected to the wireless power transmitter; and a flow switching device movably provided on the one side of the main body, wherein the flow switching device includes: a first guide tool configured to guide a first direction rotation of the flow switching device; a second guide tool configured to guide a second direction rotation of the flow switching device; and a wireless power receiver configured to supply power to the first guide tool and the second guide tool.

A self contained, 1 V to 550 V powered UVC device used to sterilize spaces like vehicle cabins or indoor rooms or spaces, while providing the ability to monitor both pre and post sterilization. While operating, the device would collect, on suitable gathering/testing media, both air that has been sterilized, and unsterilized air that passes through the media, allowing the media to be tested for the presence of both active pathogens that have not yet been killed from the device, as well as killed pathogens in the sterilized area. The UVC and media components may be integrated into one unit, or be powered and used both in combination, or as separate devices performing the sterilization and the sampling media. At the termination of UVC sterilization, additional different media has the now sterilized cabin or room air circulated through it, and with further media testing and evaluation, the efficiency/effectiveness of the sterilization process can be audited, and system operators can be advised.

A filtered air supply assembly includes a filtration unit that can be worn on a user's clothing. The filtration unit including a plurality of filters each is integrated therein and each of the filters is filter air that is pumped by the filtration unit. A mask is provided that can be worn on the user's face. A mask air hose is fluidly coupled to the mask and the mask air hose receives air from the filtration unit thereby facilitating the user to breathe the filtered air when the mask is worn. A nose air hose can be fluidly coupled to the filtration unit thereby facilitating the user to breathe the filtered air when the nose air hose is positioned in the user's nose.

The present invention discloses an automatic source-seeking indoor pollution purifying and removing device and method for airborne pollutants. The device comprises pollutant concentration sensors, a control unit, a position sensor, a power plant, a moving mechanism, a telescopic device, a pollutant collection hood, and a filtering and purifying device. The control unit can identify the actual release positions and hourly release rates of relevant pollutants according to the concentration data monitored by the pollutant concentration sensors, and can control the pollutant collection hood in the device to move to a designated position in a space, so as to realize the collection and removal of pollutants at the release position of the pollutants.

A container includes a container body and an air processing system. The container body includes a plurality of walls defining an interior space for receiving wafers. The air processing system is attached to the container body. The air processing system includes an exchange module, an air extraction module, a first contaminant removal module, a processing module, a second contaminant removal module, a controller module and a power module. The exchange module is coupled to one of the walls of the container body. The air extraction module extracts air from the container body. The first contaminant removal module is coupled to the air extraction module and the exchange module. The processing module is coupled to the air extraction module. The second contaminant removal module is coupled to the processing module and the exchange module. The controller module is configured to turn the air extraction module on and off.

A portable assembly for filtering toilet bowl odors and aerosolized toilet waste which includes a housing, preferably having a removably connected first section and second section. When utilized, the housing is disposed adjacent a toilet bowl and including an inlet and an outlet. In use, the inlet is disposed in direct fluid communication with an interior of the toilet bowl and a filter assembly is disposed within housing in fluid communication with inlet. A fan assembly within the housing includes an electrical power source and is operative to direct fluid flow successively through and from said inlet, downstream through the filter assembly and therefrom to a housing exterior through the outlet, concurrent to activation of the fan assembly.

Provided is a tower-type outdoor air cleaning apparatus that is disposed outside a facility that performs air cleaning, cleans outside air, and supplies the cleaned air, including: a tower body unit that is disposed away from the facility on one side of the facility, is provided in a tower type with a double-wall structure, in which fomentation is performed inward, air is filtered and suctioned, and is exhausted; an air supply unit that is provided above the tower body unit, in which air is supplied through an upper portion thereof and air flows in through a side portion at a plurality of locations of an outer circumference thereof and is mixed with the air supplied through the upper portion; an air ventilation filter unit that is disposed inside the air supply unit and the tower body unit, filters the mixed air supplied from the air supply unit to be supplied to the facility connected thereto, and exhausts the air circulated in the facility to the outside; a fomentation facility unit that is disposed inside the tower body unit and generates heat and electricity using solar energy for use in fomentation; and a control unit that is connected to the air ventilation filter unit and the fomentation facility unit to control the amount of air supplied by the air supply unit through the air ventilation filter unit, and controls production and transfer of heat and electricity using solar energy in the fomentation facility unit.

A personal ventilation device and method include a first duct segment and a second duct segment both held by a support structure that is configured to be mounted on a wearer of the personal ventilation device. The personal ventilation device also includes a first nozzle mounted to the first duct segment and a second nozzle mounted to the second duct segment. The first and second nozzles are configured to be disposed proximate to opposite sides of a face of the wearer and the first nozzle directs airflow from the first duct segment across the face of the wearer to form a control volume for a breathing space of the wearer.
