A fluid disinfector includes one or more disinfection units connected in series along a flow path of a fluid to be disinfected so that the fluid to be disinfected can only enter one disinfection unit after exiting from an adjacent preceding disinfection unit. The disinfection unit includes a matter layer, a light layer and a germicidal light source for generating germicidal light. The matter layer is made of porous material having a first surface to receive the fluid to be disinfected and to intercept and capture pathogens from the fluid to be disinfected; the light layer is a space permeable to the fluid and transparent to the germicidal light. When in operation, the light layer contains the germicidal light impinging on the first surface of the matter layer.

Sanitizing devices may be configured to emit sanitizing light into an environment in order to sanitize air, objects, and/or surfaces in the environment. The sanitizing light may be of a wavelength, or set of wavelengths, that deactivates, kills, or neutralizes, pathogens such as bacteria and viruses but, is not harmful to human or animal tissue. The sanitizing devices may be configured to be able to communicate with each other and/or a user over, for example, the Internet, a wireless communication network, a mesh network, and/or a near-field communication protocol in order to, for example, provide operation information and/or receive operation instructions.

An air management system for a common indoor room or space that comprises a plurality of air outflow apertures or vents, a plurality of air curtains having at least a portion of the air curtains separated from one another, a plurality of separated air suction intakes, and an air sterilization and/or air cleaning mechanism.

Pathogens (e.g., viruses or bacteria) within a volume of air can be killed or deactivated using RF energy. A plurality of phase shifters input an RF signal and output a phase-shifted version of the RF signal at their respective outputs, wherein an amount of phase shift introduced by each of the phase shifters is controllable. A phased array antenna has a plurality of microwave radiators, and each of the respective outputs of the phase shifters drives a respective one of the microwave radiators. A controller controls the phase shifters to drive the phased array antenna such that a beam of RF energy emanates from the phased array antenna and sweeps through a volume positioned in front of the phased array antenna, and the beam of RF energy kills or deactivates the pathogens.
