Choosing to use an electrostatic sprayer, fogger, mister, or vaporizer:

If trained professionals are available to apply them, people may decide to use newer technologies that either spray disinfectant electrostatically, or disperse it through fog, mist, or vapor. Cases where these technologies could be more practical include situations where there might be a confirmed case of COVID-19, use of the space is needed quickly, and some surfaces could be very hard to reach to disinfect by hand. These are sometimes used in healthcare settings after a patient is no longer using a room.

These devices aerosolize chemicals, or suspend them in the air, and they can stay in the air for long periods of time, especially if the area is not well ventilated. Aerosolizing any disinfectant can irritate the skin, eyes, or airways and can cause other health issues for people who breathe it in.

CDC does not either recommend, or not recommend, use of these devices for disinfecting community spaces for COVID-19. If they are used, they should be used with extreme caution.
