Electrostatic Sprayers are tools used to distribute or disperse chemicals onto surfaces for a variety of purposes. The difference between a standard sprayer and an electrostatic sprayer is simply that an electrostatic sprayer adds a small electrical charge to the droplets.
Most chemicals that can be used in cold (ULV) foggers can be used in electrostatic sprayers. Disinfectants, pesticides, fungicides, and other anti-microbial chemicals can be used more effectively to cover surfaces, both indoors and outside.
- Indoor Spaces: Gyms, senior centers, clinical spaces, schools, and others
- Outdoor Areas: Playgrounds, sports fields, plus farms & indoor growing areas for faster, more effective application of pesticides and other chemicals
How Electrostatic Sprayers Work
- Electrostatic sprayers work by applying a small electrical charge to aerosolized droplets when they pass through the nozzle, creating a positively charged particle.
- These charged droplets are attracted to surfaces, enabling them to adhere, or stick easily, even to difficult spaces.
- The electrostatic particles not only find and attach to surfaces more readily they also repel each other, providing complete, even coverage.
- This results in less product being used, and effective application is much faster than when using a pump sprayer or applying by hand.
Electrostatic Sprayer Benefits
Since the charged droplets seek out surfaces, usually a single pass is sufficient to cover the area, saving time—especially for large spaces. In addition, this method of application uses less product, saving you money and preventing over-use, which can be harmful.
- Less Run-Off: Instead of your chemical dripping or running off the surface, it sticks to it better. This means you’re using less to cover more.
- Reduced Overspray: Since the droplets are actually attracted to surfaces, more of the droplets find surfaces to stick to—again using less chemical solution.
- Hard to Reach Areas: When chemicals are manually applied, hard to reach areas are usually not covered as well and may be missed altogether.

Which Chemicals can be Used in Electrostatic Sprayers?
According to the US Army Public Health Center, the recommended disinfection ingredients in products used against SARS-CoV-2 virus that can be effectively used with electrostatic sprayers include the following:
- Quaternary Ammonium Chloride: This is the most effective because it is naturally positively charged and more chemically stable for the process of electrostatic spraying.
- Hydrogen-Peroxide: Strong oxidizer that degrades into oxygen and water which is safer alternative to other chemicals.
- Hypochlorous Acid: HOCL has a neutral pH, so it’s less hazardous than many products and can be effectively used in electrostatic sprayers. EfferSan Tablets can be safely stored and then dissolved and used.
- Chlorine Bleach: Up to 14% of disinfectants on the CDC’s “N List” contain bleach or sodium hypochlorite. However, it should always be mixed fresh at a 10% solution for same-day use.

In Summary
Electrostatic sprayers infuse a small positive charge onto droplets as they are being dispensed, causing them to seek and stick to surfaces, giving them a more even coating of chemicals. This saves both time and money, using less solution and preventing over-runs or dripping. These sprayers can be used effectively with several types of disinfectants and other anti-microbial chemicals, as well as pesticides.
