Delta Passengers Are No Longer Allowed to Wear Masks with Valves
Delta has been tightening rules recently in an effort to prevent the spread of the virus. Last week it announced a new health screening process for passengers who can’t wear masks on-board due to health related reasons.
Now there is a new rule for what masks are appropriate when on board a Delta flight. The airline released a statement this week saying that masks with exhaust valves are no longer allowed. “Any mask with an exhaust valve is not approved as an acceptable face mask for customers traveling on any Delta operated flight,” the website says.
These masks with exhaust valves are intended for industrial use like construction, to avoid inhaling harmful particles. They have have a small plastic piece embedded in the fabric, which is a one-way valve. It closes when you breathe in, but opens when you breathe out. So they are not a useful option to prevent the spread of virus particles.
Delta suggest that passengers use simple cloth mask that covers your nose and mouth. Plastic face shield are not sufficient either, and can only be worn in addition to a face mask. Delta also provides masks to wear it you do not have one.
