Embodiments provide an aeromedical bio-containment module for use in a cargo plane. The aeromedical bio-containment module includes a fully integrated pallet system allowing for the module to roll onto the cargo plane. An integrated set of lugs allows the module to be locked into the cargo plane floor without the use of chains or other pallets. The aeromedical bio-containment module features a ward area for safe treatment of patients, an anteroom, and an office area for personnel. The aeromedical bio-containment module operates under a negative pressure system, and includes a full air filtration system to remove pathogens, particulates, and other airborne contaminants.

Within examples, a system to provide filtered air to an enclosure for a passenger of a vehicle is described that includes a collapsible canopy hood attachable to a support structure of a vehicle, and a filter unit mounted to the support structure of the vehicle and having an output coupled to the collapsible canopy hood. The filter unit includes an air filtration component to filter air that is then output to the collapsible canopy hood.

Air purification devices include an air inlet and outlet, upstream and downstream sections in air flow communication with the air inlet and outlet and a filter removably positioned between the upstream and downstream sections to filter at least pathogens from air being passed through the filter. One or more ultraviolet (UV) illuminating sources may be positioned in at least the upstream section proximate the filter to illuminate at least an upstream surface of the filter with sufficient UV radiation to kill viable pathogens that accumulate on the filter. One or more ozone generating sources may be positioned to generate ozone in sufficient concentrations to kill viable pathogens proximate the device. The UV illuminating sources and ozone generating sources may be positioned to provide a predetermined pressure drop across the sources and air flow pattern proximate the filter, and enable the filter to be removed without handling the sources.

Methods and systems for recovering retained filtered fluid are provided.

Methods and systems for recovering retained filtered fluid are provided.

A method of monitoring indoor environments for aerosolized pathogens includes: (a) receiving a pathogen status for each of a plurality of aerosol samples collected by a plurality of corresponding air treatment devices; (b) determining whether the pathogen status for each aerosol sample changes a safety status of a corresponding indoor environment from which the aerosol sample was collected; and (c) in response to determining a change in the safety status, generating a notification associated with the change in the safety status for the corresponding indoor environment.

A filter module for sterile filtration and virus filtration of fluid media. The filter module includes a filter membrane with a porous edge structure arranged thereon and at least one anchoring element. The filter membrane with the porous edge structure is embedded in the anchoring element and serves as edge reinforcement to improve the connection of the filter membrane to the anchoring element. The texturing or surface roughness of the edge reinforcement provides an interlocking effect between the filter membrane and the anchoring element. The embedding of the filter membrane in the anchoring element provides a fluid-tight connection of the membrane to the anchoring element which prevents the occurrence of leaks in the end region of the filter module. A method for producing the filter module is also described.

A combination of nanoparticles applied onto a mask filtration system, exemplarily including 1%-10% graphene; 1%-10% titanium dioxide; 1%-10% zinc oxide; 1%-10% copper oxide; 1%-10% silicon dioxide; and balance solvent is provided.

Various embodiments of the present invention disclosed herein relate to an air cleaner, and may suck outside air and purify and sterilize the outside air, and may perform sterilization of a filter. An embodiment of the invention disclosed herein discloses an air cleaner including a body forming an appearance; a suction unit formed on the body and introduced with outside air; a discharge unit formed on the body and discharging the air introduced through the suction unit; a fan module provided inside the body and forming a flow of air introduced into the suction unit and discharged to the discharge unit; a filter unit provided inside the body to filter the air introduced into the suction unit; and a light source unit provided inside the body and irradiating light toward an inner side surface of the filter unit.

An antimicrobial filter media, which includes a non-woven fabric; and an antimicrobial agent bound to the nonwoven fabric by a binder, the antimicrobial agent including silver sodium zirconium hydrogenphosphate and thiabendazole, and the silver sodium zirconium hydrogenphosphate and the thiabendazole are employed at a weight ratio of 1:1.5 to 1.5:1, to an air cleaner including the same, and to a process for preparing the same. The antimicrobial filter media includes silver sodium zirconium hydrogenphosphate and thiabendazole, as an antimicrobial agent, at a specific weight ratio. As a result, it is possible to effectively filter harmful microorganisms to supply purified air, to have excellent antibacterial, antiviral, and antifungal properties at the same time, and to further enhance the durability and lifespan characteristics by virtue of excellent filter damage prevention effect.
