    Electrostatic Spraying v. Fogging

    Disinfection processes have become an extremely vital part of cleaning protocols for businesses. Before the pandemic, businesses generally practiced basic cleaning methods, but since the pandemic, ensuring your business is clean goes well beyond basic daily cleaning. Everyone is doing their homework about disinfecting and sanitizing to make sure their working environment is safe. While researching, you have probably come across two main types of commercial disinfecting; electrostatic spraying and fogging. Both methods use a disinfecting solution, and both accomplish the task, but there is a significant difference between the two processes. Although they both are effective at disinfecting, they provide different protection levels, so to help you choose the best method for your needs, here are the primary differences between electrostatic spraying and fogging.

    Electrostatic Spraying

    Electrostatic spraying means that the sprayer provides a thorough, even coating of disinfectant throughout the area being “treated.” As the disinfectant solution is sprayed through the device, the droplets get an electrical charge, creating a 3-D wrapping effect. This wrapping effect provides a variety of benefits, including; It allows the droplets of disinfectant to wrap around and evenly coat a vast array of surfaces to ensure complete coverage. For instance, the electrostatic liquid will wrap around the edge of desks and tables, allowing it to cover a larger area.

    The droplets’ electrical charge is drawn to surfaces, which provides an even layer of disinfecting, and the solution bonds better with the surface it is directed towards.

    Electrostatic spraying can be used to disinfect any surface or object that the device is pointed towards, and the wrapping effect provides more thorough encapsulating with the disinfectant.


    Fogging is generally used for the application of fungicides, biocides, pesticides, and disinfectants. The equipment used for fogging generates a mist or a fog made of ULV (ultra-low volume) droplets. Fogging creates a form of vaporization that destroys airborne and surface-based pathogens. When fog is used, there is no need to move equipment or furniture for the treatment to work. This method is thought to be the easiest and quickest way to disinfect large areas with minimum disruption to your business. Fogging is especially beneficial in large commercial areas because it disinfects both the air and any surface that the disinfectant comes in contact with. Foggers are also beneficial for HVAC systems and other tight spaces because the disinfectant can be forced into the area; however, they may not be as effective on vertical surface areas, such as tables and chairs.

    Do Foggers and Electrostatic Sprayers Use Different Disinfectants?

    Both foggers and electrostatic sprayers can use various solutions; it is essential to ensure the solution being used is safe for use in the specific machine of choice and that the solution is effective for the intended use. For instance, a professional-grade disinfectant may be used in both machines. Still, it’s vital to ensure that the solution being used is non-irritant, non-corrosive, non-toxic, and a water-based solution. Any solution that is being used with a flash-point should be avoided when using an electrostatic sprayer. The safest way to ensure the space is being disinfected with the appropriate solution and equipment is to hire a professional commercial disinfecting company.

    One of the most common questions is “which are better, foggers or electrostatic sprayers”. The answer varies because it depends on the surfaces you are attempting to disinfect and protect. For instance, foggers are often recommended for large open areas with excessive amounts of furniture and other hard surfaces, but they are also ideal for tight spaces, such as HVAC ducts. Electrostatic sprayers are often recommended for areas containing furniture, hard surfaces, and other tight areas where the droplets can be attracted.
