The Relative Exposure Index Calculator provides a method for assessing the airborne transmission of SARS-CoV-2 in an indoor space. A simple method is provided, allowing the user to describe the dimensions, breathing rate, respiratory activity, occupation duration and ventilation provision in a given space, allowing users to compare scenarios that involve air cleaners with those that do not.

A more complex calculation is also provided, allowing users to assess the impact of mitigation measures in reducing relative risk of secondary transmission.
