A certain type of N95 may do not work well for protecting
Experts say certain N95 masks with front valves protect the user but don’t prevent that person from spreading COVID-19 to others nearby.
Experts are warning the public against wearing certain types of N95 face masks with front valves.
They say the masks protect the people wearing them but do not stop virus droplets from escaping and infecting others.
The masks are designed for construction workers to use to keep out dust and other particles.
Not all N95 respirator masks are created equal.
In fact, you may unknowingly be wearing one that does more harm than good when it comes to preventing the spread of COVID-19.
It was a reminder that the city’s original public health order requiring face coverings said that any mask with a one-way valve was not to be used.
“Valves of that type permit droplet release from the mask, putting others at risk,” the order stated.
Experts who spoke with Healthline agreed.
“The virus can be transmitted through the valves, which offer no filtration at all,”
“Any mask with a one-way valve is only going to protect the person wearing it. It won’t protect anyone around that person from potential exposure to virus particles they exhale,” he told Healthline. “It may give the people surrounding them a false sense of security.”
