Fog is made with 1500PSI High Pressure. Some of the others use heat, making steam. Read all the chemicals it will use before you buy one. And some just mist the area. Automate with a pool injector to inject HOCL into the cool misting systems that many outdoor cafes already have.
Adding a charge to disinfectants can change them. The fogger videos are to show fogging is good but in some cases, the static charge is not. Hypochlorous could be in the fog in effective intervals. This is just some things I found.
