Electrostatic spraying versus fogging
Electrostatic spraying The application and PPE requirements are very similar to that when carrying out handheld fogging. The basis of electrostatic spraying is similar to fogging, but there is an important additional process that takes place. At the tip of the sprayer, as the sanitiser leaves, it is positively charged with an electrode.
As nearly every surface that we aim to sanitise has a negative charge, the positive charge that is applied therefore means that the negative surface magnetically attracts the positively charged sanitiser. This in turn causes a ‘wrap around’ affect, almost guaranteeing complete surface coverage.
Electrostatic spraying versus fogging
For an example of how this works, take a look at the diagrams above.
Electrostatic spraying versus fogging If targeting specific areas in-between client meetings,

such as tables and chairs, or individual toilet cubicles throughout the day, then electrostatic spraying would be the preferred option as this method is prone to less atomisation of sanitiser and is a lesser risk to those in the same vicinity.
Fogging, however, is better suited to those areas that are vacant after hours, such as office buildings, restaurants and gyms. The benefits of fogging ensure complete sanitiser coverage of all surfaces rather than specifics.
It is important that you choose the correct form of disinfection for your business, and the health of your employees and customers. Take extra precaution when risk assessing the environment to be sanitised before deciding. In either application, the efficacy of the sanitiser is the same.
