How electrostatic spraying works
Electrostatic sprayers give droplets of disinfectant an electrical charge as they leave the nozzle. Charged droplets are attracted to surfaces and spread out, coating fronts, sides and some hidden areas more evenly than a trigger spray bottle. That makes it efficient for disinfecting large spaces with many surfaces: classrooms, offices, gyms, vehicles, waiting rooms and common areas.
What it does and doesn't do
Electrostatic spraying is an application method, not a separate kind of disinfection. Results depend on:
- Cleaning first. Disinfectants work poorly on dirty surfaces. Visible soil is removed before spraying.
- The right product. EPA-registered disinfectants approved for electrostatic application, effective against the organisms of concern.
- Contact time. Surfaces must stay wet for the time on the product label.
- Label directions. Including re-entry intervals, surfaces and any rinse requirements for food-contact areas.
Sprays don't replace cleaning heavily soiled areas, and they don't remove biohazards like blood or bodily fluids, which require physical cleanup first.
How a service visit works
- Walkthrough to identify spaces, high-touch surfaces and sensitive equipment to cover or avoid.
- Pre-clean high-touch surfaces where needed.
- Apply disinfectant with electrostatic sprayers in a planned pattern.
- Observe contact time and re-entry intervals.
- Document areas, product, EPA registration number and time.
Where it's used
Offices, schools, daycares, gyms, places of worship, healthcare waiting areas, fleet vehicles, transit and homes after illness.
Common questions
Is electrostatic disinfection safe?
When EPA-registered products are used according to label directions, including re-entry times, yes. We share product information on request.
Does it kill COVID-19 or flu?
Many registered disinfectants are effective against these viruses when used as directed. Product choice depends on the organism, and we don't make health claims beyond the product label.
How often should we disinfect?
It depends on occupancy and risk. Many facilities use scheduled programs with extra visits after illness reports.
