(a) Time-averaged PM concentrations over the range 0.5-\(2.5\,\mu \hbox {m}\) observed near the mask when tap water, salt solution (brine), and sugar solution (concentration \(=125\,\hbox {g/L}\)) are used in the mitigation module. (b) Comparison of the PM decay rates and settling times for mist generated by the three solutions. The sugar solution results in the shortest settling time.
