Steramist requires continuous attention by the user, thus it may not be appropriate in settings with limited human resources.
- Disinfection takes 5 seconds per square foot
- Room cleaning can be done in 10 minutes (varies by size)
Consumables must be purchased from TOMI (which currently only operates in Europe, North America, and China).
Steramist was awarded by USAID for ‘Improving the Safety of Health Care Workers’ to be used for disinfection to eradicate Ebola and strengthen local healthcare systems.
The deployment of this technology should be coupled with culturally appropriate training methods to ensure safe use.
