Table 3.

Equation (form: axb + c) for Mask filter-Docc correlation curves in limit conditions as drawn by Fig. 16. In the equations, x is mask filter, while y is Docc. The table also shows the limit of the mask filter values domain in which the equation could be applied, as well as the R2.

initial infector % from 1.40% to 3.00% from 3.00% to 5.00% over 5.00% to maximum value (10.00%)
Equation: y = axb + c y = 1.29x2.09 + 0.35 y = 0.87x2.36 + 0.24 y = 0.93x2.76 + 0.17
