A device for dispensing a disinfecting agent includes a container made of a non-oxidizing, non-elastic material of a predetermined volume configured to store a predetermined amount of a disinfecting agent and a predetermined propellant at a predetermined pressure. A diffusion device coupled to the container is configured to nebulize a fog of the disinfecting agent into a space having a predetermined volume and pathogens therein. The container and diffusion device and a combination of predetermined volume of the container, the predetermined amount of the disinfecting agent, and the predetermined pressure of the propellant are configured for the space such that the fog of disinfecting agent disinfects the pathogens in the air and surfaces of the space.
