The Omicron ventilation tool developed by the US Center for Disease Control provides a snapshot into ways in which you can improve the quality of air in your workplace or home to mitigate the spread of Covid-19. The ventilation tool provides a visual demonstration of how you can effectively reduce aerosols using ventilation methods to reduce transmission risks of the virus.
Ventilation and air filtration are accepted methods of risk reduction at the workplace but also should be combined with a range of other measures to stop the spread of COVID-19.
To use the tool scroll to the inputs on HVAC, portable HEPA Filters, additional ventilation, and open windows and watch the effect of ventilation on the airborne virus.
Notes: The results are estimates and might not be exact in the real world. The model assumes a visitor is staying for 4 hours in a 1,000 square-foot (92 m2) space and is not wearing a mask. This size is used because 1,000 square (92 m2) feet is the size of an average one-bedroom apartment in the USA or about one floor of a larger home. The first panel shows particle reduction based on levels that would be in the air at the end of a 4-hour visit. The second panel shows particle reduction 1 hour after the visitor leaves.
