How Much Does Electrostatic Disinfection Cost?

How one-time and scheduled service change electrostatic disinfection cost

A one-time treatment carries the full cost of mobilizing a crew, often after hours and sometimes at short notice, so it is priced per visit with a minimum charge. A scheduled program spreads that setup across many visits, lets the vendor plan routes and staffing, and usually lowers the per-visit and per-square-foot figures. Adding spraying to an existing janitorial program is often the cheapest option, because the crew is already on site.

Why square footage is only part of electrostatic spraying cost

A sprayer charges droplets so they spread and wrap around surfaces, and it covers open areas quickly. The time goes elsewhere. Densely furnished rooms, many small offices, electronics and paper that must be covered or avoided, and soft surfaces the label may exclude all slow the job. Most of all, disinfectants are applied to clean surfaces: many labels direct users to pre-clean soiled surfaces first, because dirt and residue shield microorganisms. Spraying does not replace cleaning, so a credible price includes the pre-cleaning labor, not just the spraying time.

Product choice and label rules

The product label governs everything, and it also drives cost. Under the federal pesticide law (FIFRA), using a registered disinfectant in a way its label does not allow is a violation, so electrostatic application is appropriate only for products whose labels include directions for it. In California, disinfectants also need registration with the Department of Pesticide Regulation. EPA's List N names products that meet its criteria for use against SARS-CoV-2, and the label sets the contact time, the PPE, the surfaces allowed and whether food-contact surfaces need a rinse afterward.

Concentrates mixed on site cost less per square foot than ready-to-use solutions, but not every concentrate is labeled for sprayers. Ask for the product name and EPA registration number with each quote, and read the directions for use before comparing prices.

Re-entry time and scheduling

The label's contact time and any re-entry or ventilation instructions decide when people can return. That is why most electrostatic work happens in the evening, overnight or on weekends, when rooms can stay closed long enough. Sites that never close are treated zone by zone, which takes longer and costs more than treating the whole building at once. Server rooms, labs and areas with sensitive equipment need a plan for what is sprayed, what is wiped by hand and what is left alone.

Questions to ask about disinfection service pricing

Two quotes for the same space can differ widely because they assume different products, surfaces and amounts of pre-cleaning. Before choosing, ask every vendor to answer these points in writing so that the numbers you compare describe the same service.

• Which product, with its EPA registration number
• Does the label include electrostatic sprayer directions?
• What are the contact time and re-entry instructions?
• Is pre-cleaning of soiled surfaces included?
• Which surfaces are sprayed and which are wiped by hand?
• How are electronics, paper and food-contact areas protected?
• What record is left: date, areas treated, product used?

How EBS prices disinfection work

EBS offers recurring, one-time and after-hours disinfection with EPA-approved products, including full-space electrostatic application when a situation warrants it. Its protocols follow CDC, OSHA and manufacturer guidelines on product use and dwell time, and the plan covers high-use surfaces, restrooms, breakrooms and meeting rooms. The walkthrough settles whether a space needs spraying, targeted wiping or both, so the price is tied to what the building actually needs.
