What Is an Electrostatic Sprayer?

Electrostatic sprayers, also referred to as electrostatic disinfection sprayers, are cutting-edge devices designed to atomize disinfectant chemicals, imparting an electrostatic charge to the resulting mist. This electrostatic charge enhances the chemical's adhesion to surfaces and objects, ensuring thorough coverage. Typically, these sprayers comprise a specialized gun, a rechargeable battery pack, and a container for the disinfectant.

How Electrostatic Sprayers Work

These sprayers operate by combining ambient air with disinfectant to generate an aerosolized mist. The mist is then charged with a positively charged diode tip or electrode in the sprayer nozzle. The positively charged droplets bond with negatively charged surfaces, facilitating effective disinfection.

Benefits of Electrostatic Disinfection

  1. Reduced Labor Time: Electrostatic sprayers significantly diminish the time required for disinfection compared to traditional methods, potentially saving up to 80% of the time spent.
  2. Decreased Usage of Disinfectant Chemicals: Some studies suggest a reduction of up to 65% in disinfectant chemical usage, leading to cost savings.

    Electrostatic Sprayer Coverage Misconception

    Contrary to common belief, electrostatic sprayers have limited "wrap-around" coverage. Research indicates that their effectiveness may be compromised, and reduced contact time on surfaces may impact overall efficacy.

    Duration of Electrostatic Treatment

    The duration of electrostatic spraying treatments varies based on surface type, environmental conditions, disinfectant solution, and contamination levels. While some treatments offer immediate protection lasting several hours, others provide longer-lasting protection for multiple days.

    It's crucial to integrate electrostatic spraying into a comprehensive cleaning and disinfecting program and not rely solely on it for infection prevention.

    Safety Precautions for Electrostatic Sprayers

    The CDC neither recommends nor discourages the use of electrostatic sprayers but emphasizes cautious use. Potential health risks include irritation from aerosolized chemicals and skin irritation due to surface residue. Recommendations for safe use include:

      • Trained professionals should operate sprayers.
      • Use only approved disinfectants.
      • Follow manufacturer's instructions for safety, use, and contact time.
      • Employ appropriate personal protective equipment (PPE).
      • Use sprayers only in unoccupied rooms and with caution in food preparation or child-play areas.

      Can Electrostatic Sprayers Eliminate COVID-19?

      As of winter 2023, the EPA has not directly tested electrostatic sprayers for efficacy against SARS-CoV-2. Choosing a disinfectant from the EPA's "List N" is essential, as electrostatic sprayers are only as effective as the disinfectant being sprayed.

      Importance of Clean Air in Indoor Environments

      While electrostatic sprayers address surface disinfection, maintaining clean shared air is equally vital. Airborne transmission of viruses, including COVID-19, emphasizes the need for improved air filtration, ventilation, and indoor air quality technologies to create truly healthier indoor environments.

      In conclusion, electrostatic sprayers play a valuable role in surface disinfection, but a holistic approach to indoor health involves addressing air quality alongside surface cleanliness. Organizations should carefully consider both aspects for comprehensive protection.
