A method for sterilizing viruses comprises generating a beam having radiating energy therein at a predetermined frequency for generating mechanical eigen-vibrations in a spherical virus to destroy the spherical virus and a predetermined cartesian beam intensity for imparting transverse shear forces to an icosahedral lattice structure of the spherical virus to destroy the icosahedral lattice structure of the spherical virus using beam generation circuitry. A resonance frequency of the spherical virus for inducing the mechanical eigen-vibrations in the spherical virus is determined based upon a size, geometry, and protein material of the spherical virus using a predetermined three-dimensional acoustical model of mechanical vibrations within the spherical virus. The beam generation at the predetermined frequency and the predetermined cartesian beam intensity is controlled using a controller responsive to the determined resonance frequency. The predetermined frequency equals the resonance frequency of the spherical virus. The beam on is radiated a predetermined area to destroy the spherical virus at the predetermined area using radiating circuitry. The mechanical eigen-vibrations at the resonance frequency of the spherical virus determined by the predetermined three-dimensional acoustical model are induced within the spherical virus to destroy the spherical virus responsive to the predetermined frequency. The transverse shear forces are imparted to the icosahedral lattice structure of the spherical virus to destroy the icosahedral lattice structure of the spherical virus.

A method and apparatus for sterilizing a medical instrument, such as a dental instrument. The method includes placing the medical instrument in a chamber, providing a sterilizing agent including recombined ionized humidified air, controlling the temperature of the medical instrument and/or the chamber such that the temperature of the medical instrument is below the temperature of chamber, and at least partially condensing the sterilizing agent onto the instruments.

A purification device for cleaning one or more surfaces of a vehicle, the purification device configured to apply a purification process onto the one or more surfaces of the vehicle, the purification device includes a heating device for increasing a temperature of the surface.

There is provided a system and method of cleaning surfaces of an enclosable environment of a contamination comprising a microbial and viral load. The method includes the steps of sealing the enclosable environment and placing water, and a solid or gel pack, into a container and generating a vortex the container by rotating an impeller. The agitation causes the solid or gel pack to release a gaseous cleaning agent. An air-borne spray exiting from the container spreads throughout the enclosable environment to contact the surfaces to be cleaned within the enclosable environment. The enclosable environment is maintained closed for an effective time period while the air-borne spray dwells on the surfaces to eliminate or substantially reduce the load of the contamination.

A system and method for cleaning, rinsing, and sanitizing a container is disclosed. The system has a sanitizing agent chamber for storing a sanitizing agent, the one or more solution chambers in fluid communication with the container, a pump in fluid commination with the sanitizing agent, wherein the pump is in communication with a gas, and at least one spray nozzle fluidly connected to the at least one solution chamber via a conduit positioned within the container, wherein the spray nozzle comprises a housing inside which the sanitizing agent is mixed at pressure with the gas to disperse the sanitizing agent and gas mixture into the container for sanitizing the container.

Provided herein is a method of treating material that is contaminated with a virus, comprising exposing the material to vapor, wherein the vapor is produced by heating and/or vaporizing a dry cleaning solvent, and wherein the method at least partially deactivates the virus.

A device for cleaning a handle, includes a handle including a gripping surface to be disinfected, an application member for applying a cleaning liquid to the gripping surface, and cleaning liquid supply including at least one reservoir for receiving cleaning liquid and distributing it to the application member. The application member includes at least one buffer reserve arranged in contact with the gripping surface. The device includes a unit for actuating the application member, including a driver configured to move the buffer reserve and/or the gripping surface relatively with respect to one another so as to apply cleaning liquid to substantially the entire gripping surface during this movement.

A footwear sanitization system or floormat which may have one or more zones to. The zones may include a disinfecting zone, a drying zone, a scraping zone that are used to perform different procedures on the footwear for the purposes of cleaning or sanitizing the footwear when the footwear is in or on the zone.

Embodiments of a unified airflow system for ultraviolet disinfection devices are disclosed. One embodiment of the present disclosure includes a unified airflow assembly and a control unit. The unified airflow assembly provides a shared airflow passage between a UV source and an airflow accessory capable of extracting contaminants from a target surface using a suction airstream. The UV source may be fluidically disconnected from the airflow accessory. The unified airflow assembly may include at least one air restriction unit in the shared airflow passage for manipulating a suction airstream therein. The control unit may be configured to drive the at least one air restriction unit to restrict the suction airstream to only one of the UV source and the airflow accessory.

A method of cleaning and sterilizing a drink filling apparatus including a CIP process of circulating a cleaner in a drink supply piping to remove foreign matter on an interior of the drink supply piping, and an SIP process of sterilizing the interior of the drink supply piping. The processes are performed at the same time or in sequence without an interruption between the two. The SIP process uses the cleaner to sterilize the interior of the drink supply piping. After the SIP process, while the cleaner is kept circulating, a temperature condition at a predetermined position in the drink supply piping is adjusted to a temperature setting for manufacture, after which the cleaner in the drink supply piping is removed.
