A sanitizing device for a vehicle (20) which, when in use, is adapted to deliver chemical agents and/or gases for sanitizing the interior of a vehicle (10). Additionally, the sanitizing device (20) integrally comprises a pressure sensor (30) adapted to monitor the pressure inside the vehicle (10) when the sanitizing device (20) is in use. In particular, when the door (11) is opened, the sensor (30) detects a pressure gradient, thus interrupting the delivery of the chemical agents and/or gases inside the vehicle (10).

A ventilation system for removal of aerosols including bacteria and viruses such as the COVID-19 Coronavirus, and airborne debris from dental/medical operatories is provided. This ventilation system is comprised of (1) a stationary hood, secured at a specific distance above a patient that pulls contaminated air from the operatory, (2) ducting that carries the contaminated air away from the operatory, (3) a UV Ozonator that treats the air and cleans it of viral and bacterial aerosols and airborne debris before (4) expelling it to the outside through a specified length of terminal duct. The combination of certain embodiments in this invention create an effective means of aerosol and airborne debris removal in dental/medical operatories or other indoor spaces.

A system for sanitizing the interior of vehicles that provides an integrated computer system, a body that contains the components of the system, devices for transferring ozone to a vehicle, and a sterilizer for removing ozone from the vehicle.

The present disclosure relates to an air modifying device for extending the shelf life of a fresh product and to methods of extending the shelf life of fresh products. Certain embodiments of the present disclosure comprise an air modifying device for extending shelf life of a fresh product. The device comprises a hollow body, one or more means for moving air or a gas through the hollow body, a surface within the hollow body, the surface comprising a metal oxide, and a source of UV light within the body to direct UV light onto the surface comprising the metal oxide, wherein irradiation of the metal oxide with the UV light modifies the air or gas moved through the device so that release of the modified air or gas from the device into the atmosphere around the fresh product extends the shelf life of the fresh product.

A method for degrading organic fractions in cooling circuits in industrial plants, in particular plants in the metallurgical industry, including the following steps: adding bacteria to the cooling circuit, wherein the bacteria are suitable for degrading the organic fractions in the cooling circuit, and disinfecting the aerosol generated in a cooling tower of the cooling circuit. A cooling circuit for an industrial plant is also disclosed.

Technologies for sanitizing medical devices are described. In particular, sanitizing systems, components of sanitizing systems, and methods for sanitizing medical devices such as continuous positive airway pressure (CPAP) equipment are described. In embodiments, the sanitizing systems include a sanitizing gas generator and a base including at least one exhaust port and a filter.

A system for providing a centralized aerosol source extraction and filtration system is disclosed. The system includes an aerosol capture component coupled to a set of aerosol capture ductwork being located at or near a patient's mouth while treatment is being provided and is coupled to a set of aerosol capture ductwork, a filter and fan component coupled to the set of aerosol capture ductwork for generating the necessary pressure differential to draw the air about the patient's mouth into the aerosol capture component along with any airborne particulates, contaminants, and pathogens, and a recycled clean air component for returning recycled clean air back to patient areas and workspaces through a set of recycled clean air ductwork arranged to create positive and directional airflow throughout the office space. The filter and fan component has one or more filter layer types to remove particulates, contaminants, and pathogens from an air flow received from the set of aerosol capture ductwork.

A germicidal panel light includes a housing, a sterilization component, a fan component and a lighting component; the housing provided with a mounting cavity as well as an air inlet and an air outlet connecting to the mounting cavity, inner wall of the mounting cavity forming an air guiding plane corresponding to the air inlet and the air outlet respectively, the appearance of the housing provided with a containing groove whose inner wall is provided as a reflecting surface; the sterilization component is provided in the mounting cavity; the fan component is provided in the mounting cavity and is provided at intervals with the sterilization component; and the lighting component is provided in the containing groove. The germicidal panel light has an air guiding plane in the mounting cavity nearby the air inlet, so air can be guided into the mounting cavity, air flows slowly, and noises are reduced.

An exhaled air purification device comprising an exhaled air purification chamber and an air collector capable of capturing, collecting, and cleaning exhaled air of an individual sitting in front of the exhaled air purification device.

An air purification unit and/or system for an environment with multiple seated individuals, including an air collector and air purification chamber, to be used independently from or in conjunction with the environment's air handling system.
