There is provided an isolator that is capable of improving work efficiency by shortening a sterilization time, and that is capable of securing a sterility assurance level. An isolator, in which a circulation fan above a work room supplies clean air to the work room via a HEPA filter, includes: the work room; a front door provided in a front surface of the work room; a glove provided in the front door; and an air supply unit that causes an air supply HEPA filter to clean air taken in from an air supply airtight damper, and that causes an air supply fan to supply the clean air into the isolator, when work is performed. When a sterilization gas is removed, the air supply unit is configured such that the air supply fan circulates the air inside the isolator through a sterilization gas-removing catalyst.

A modular anti-microbial aerosol atmospheric effect delivery system includes an air compressor, a haze solution reservoir, and an artificial snow solution reservoir in a system enclosure and an electronically controlled haze module and artificial snow module mounted above an attendee room. The haze module is connected to the air compressor and the haze solution reservoir by a hose system. The artificial snow module fluidly is connected to the air compressor and the artificial snow solution reservoir by the hose system. The artificial snow solution reservoir contains an artificial snow solution including sodium lauryl sulfate and citric acid. The haze solution reservoir contains a haze solution propylene glycol or tri-ethylene glycol, and at least one anti-microbial component selected from hydrogen peroxide and citric acid. The solutions are safe and antivirally effective to kill aerosol microbes suspended in the air, reducing transmission of undesirable microbes amongst attendees and workers within indoor environments.

A robotic, mobile apparatus (1) for treating an enclosed space (53) comprises a wheeled carriage (3) on which a treatment device (2) is mounted. A controller (14) is provided that is configured to control operation of the wheels (12) of the carriage (3) and to operate the treatment device (2). A human-machine interface (HMI) (5) is also provided that is in communication with the controller (14) and is operable to start and stop a treatment procedure. The treatment device (2) is electrically powered via a mains supply using an electrical cable (30) and a management system (31, 37) is provided that controls the tension of the electrical cable (30) in order to prevent the wheeled carriage (3) from becoming tangled in the electrical cable (30) when it moves robotically. Preferably, a pivotally mounted arm (35) extends from the wheeled carriage (3) and the electrical cable is threaded around an end of the pivotally mounted arm (35) whereby the cable (30) is guided around the exterior of the wheeled carriage (3).

Aspects of the invention include methods for reducing a pathogen population. Methods according to certain embodiments, a source of the pathogen is contacted with a plurality of microdroplets having one or more reactive oxygen species. In certain embodiments, methods include producing the microdroplets by outputting an aqueous composition from an orifice of a flow channel to produce a plurality of microdroplets having one or more reactive oxygen species. In certain embodiments, methods include producing microdroplets through the condensation of water by contacting solid carbon dioxide with an aqueous composition such as by dropping the aqueous composition on the solid carbon dioxide or submerging the solid carbon dioxide in the aqueous composition to produce a plurality of microdroplets having one or more reactive oxygen species. Compositions of a plurality of microdroplets having one or more reactive oxygen species are also provided. Systems for practicing the subject methods are also described.

A plume cleaning system for a toilet is integrated with a toilet. In one example, a plume cleaner assembly adjacent to a toilet seat is independently removable with respect to the toilet seat. The plume cleaner assembly may include a plume cleaner, apertures, and a fan positioned to draw plume air through the plurality of apertures for treatment by the plume cleaner and expel the treated plume air out of the plume cleaner assembly in a direction at an angle to the apertures. In another example, a plume cleaner assembly with the toilet seat may include at least a fan, an electrostatic collector, and a mist generator. In another example, a plume cleaner assembly is integrated in a tank of the toilet to generate a sanitization fluid that is channeled into the toilet bowl through an overflow tube and/or rim channels.

The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air.

A sanitization system for an aircraft cabin may comprise: a cabin of an aircraft; a light system including a lighting unit configured to emit an electromagnetic radiation output between 300 and 430 nanometers (“nm”); an external reactive oxygen species (ROS) generator in fluid communication with the cabin, wherein the sanitization system is configured to disinfect a target area of the cabin by targeting the target area with the electromagnetic radiation output and the ROS.
