From: Salt and surfactant coated filters with antiviral properties and low pressure drop for prospective SARS-CoV2 applications

Figure 3

(A) Pressure drop vs. salt loading for drop-cast coating and nebulization coating; rapid increase in pressure drop after 6 mg/cm2 of loading for nebulization coating; (B)The effect of multilayer filters on the pressure drop for NaCl-Tween 20 and NaCl in comparison with uncoated filter. The variation in pressure drop between Tween 20 coated and uncoated filters is less than the uncertainty of the experiment.
