It can be a lot harder to instantly test mask efficacy for PPE utilizing a human subject, so simulations have to be used as a substitute. Masks may be made of various materials and designs which affect their filtering capability. Another examine used a manikin and visual smoke to simulate coughing, and found that a stitched material mask was the most effective of the examined designs at source control, reducing the jet distance in all instructions from eight toes to 2.5 inches . There are currently no studies that measure the impact of any type of masks on the quantity of infectious SARS-CoV-2 particles from human actions.
