In tests with masks with valves, the droplets have almost as far as possible in the tests where the manikin wasWithout any kind of face recovery at all.
"When you compare the videos side by side, the difference is striking,"Matthew RestmatesThe NIST research engineer who created visualization, said in a statement. "These videos show how the valves allow the air to leave the mask without filtering, which defeats the goal of the mask."
In conclusion, restess stays reiterated one of CDC's most often repeated reminders: "I do not wear mask to protect me.
