Key Differences

  • Solution Droplet Size

    Both units able to produce 30-70 micron droplets. ULV Foggers can adjust size based on liquid flow adjustment. Electrostatic units have to change nozzle to adjust droplet size

  • Electrostatic Charge

    ULV Fogging passively distributes drops over the surface using gravity. Electrostatic units apply a bulk charge to the solution or induce a charge at the nozzle, causing the solution to distribute more evenly and wrap around neutrally grounded objects.

  • Air Flow

    ULV Fogging uses air flow to draw solution into the nozzle. Electrostatic units pump liquid through the nozzle, then have optional air flow to further disperse. Air flow from Electrostatic is less, with lower risk of blowing items over.

Disinfection Options

Looking to Disinfect your space more Efficiently?

Electrostatic and ULV Fogging are listed almost interchangeably on some sites, but there are some key differences to consider.

Coverage Area

  • Battery Powered Electrostatic able to cover larger area without re-adjusting for extension cords

  • ULV Foggers emit more volume of disinfectant and can be applied from further away

  • ULV Fogging requires more movement around each object. Electrostatic allows for 'wrapping' effect of solution

Cost

  • Electrostatic units generally more expensive with battery cost, induction charge and increased complexity

  • ULV Fogging has higher ongoing cost with increases disinfectant use

  • Cost of protective equipment (Respirator) more likely to be required with ULV Fogging

Difficulty of Use

  • Both Electrostatic and Fogging can be learned with online material and practice. Testing is similar for both to check for adequate coverage

  • Electrostatic Disinfection will allow for earlier re-entry time due to less suspended solution

  • Dispersion from Electrostatic aided by charge. Lower air flow reduces risk of knocking items over
