A pathogen-deactivating fibrous material is coated with salt crystals or salt crystal layer. The salt crystals or coating on the supporting fibrous material layer dissolves upon exposure to pathogenic aerosols and recrystallizes during evaporation of water from the pathogenic aerosols. Recrystallization of the salt deactivates pathogens. The pathogen-deactivating fibrous material can be used in a sanitizing fabric, an air filtering device, such as respiratory devices, masks, furnace filter devices, air conditioning device, vehicle cabin filter device, etc., and can provide a universal personal protection for preventing infections.

Disclosed herein are systems and methods for decontaminating surfaces from human coronaviruses, such as SARS coronavirus 2 (SARS-CoV-2), and structures for decontamination from human coronaviruses. A structure for decontamination includes a first surface and a decontamination layer on the first surface. The decontamination layer comprises a nanostructured photocatalyst. Human coronaviruses on the decontamination layer are exposed to UV radiation and/or visible light. After the exposure, the human coronaviruses on the decontamination layer are inactivated. In some embodiments, the decontamination layer can include additives and/or an electrical bias can be applied to further reduce the exposure time required for viral inactivation.

This control system includes a ventilation device which performs exchange between gas inside a room including an infectious object and gas outside the room, to discharge and remove the infectious object; a supply device which supplies an inactivating substance, for inactivating the infectious object, to inside the room to inactivate and remove the infectious object; and a control device which controls the ventilation device and the supply device. The control device switches between a first mode and a second mode which is different from the first mode. The first mode is for performing at least one of a first operation whereby, on the occasion of increasing the removal capability of one of the ventilation device and the supply device, the removal capability of the other is decreased, and a second operation whereby, on the occasion of decreasing the removal efficiency of one of the ventilation device and the supply device, the removal efficiency of the other is increased.
