Another aspect to consider, according to Steve Lustig, associate professor and the associate chair of research in chemical engineering at Northeastern, is whether your mask has waterproof properties.
“When you get sprayed, because someone sneezes on you or someone coughs, or you cough, you’re loading this mask material with all this liquid,” he says.
“And if that liquid permeates all the way across the mask, well, then you could be imbibing the virus just because it flows by liquid.”

Waterproof material isn’t the only way to avoid that damp disaster, however.
The researchers found that duckbill-shaped masks – masks that are shaped and stiff enough to stay away from touching your mouth – are more effective, too.
