Coverage Area

  • Backpack type units can cover up to 50,000ft2/hr and save time on refill of solution

  • Check the battery life, and option to purchase spare battery if required

  • Air assist units improve coverage from distance and further dispersion

Ergonomics

  • Consider the weight of unit, there are cart mounted vs. backpack

  • Non air assist handheld units beneficial in tighter spaces like bathrooms

  • Check what position your arm/hands will be in over extended periods

Charge Type

  • A positive charge is preferred to negative due to interaction with disinfectant solutions

  • One unit charges the bulk solution, while others induce a charge on the droplets at the nozzle

  • Check that the unit is UL/CSA certified for your area

Reliability

  • Manufacturers have ramped up production, some parts and support are challenged. Best experience with North American made with local support

  • Consider your cost of reliability: do you need a spare sprayer or parts, or a professional service as a back-up option?

  • Check the warrantee conditions
