The Aeris™  banknote decontamination system effectively neutralizes biohazards (viruses, toxins, and bacteria) on paper and polymer banknotes to help protect the public and banknote processing staff. Efficacy of biohazard decontamination was tested in collaboration with Nova Biologicals Inc. laboratory.

The Aeris 400 system, our largest capacity machine, enables the decontamination of 120,000 –  150,000 notes per processing cycle and allows for immediate reintroduction of the banknotes. With a one hour processing time per decontamination cycle, more than one million banknotes can be processed in an eight hour shift.


In collaboration with Nova Biologicals, tests were performed to measure the efficacy of Aeris banknote decontamination.  The testing determined:

  • A  reduction in viral load to non-detectable limits.
  • A 104 reduction in bacteria was found, which is in line with the efficacy of household disinfectants such as Lysol.
  • E. Coli, Staphylococcus, and Spores were not able to be detected after Aeris cleaning.
  • Tests measured a >99% reduction in:
    • heavy metals (mercury)
    • pesticides, and insecticides.
