During the ongoing coronavirus pandemic, as more Americans are forced to wear masks, authorities have cautioned that counterfeit N95 masks are entering the market. There have been incidents of hospitals and first responders buying defective face masks in New Jersey, West Virginia, Missouri, and elsewhere over the last few weeks.
It's not just fake masks that pose possible health risks. In some cities, masks with air valves are banned because they are ineffective in protecting the wearer against infecting others around them. When you take your dog for a walk, whether you are a frontline medical worker or just wearing a mask, here how you can tell whether your mask is safe to wear, not only for you but for others.
The N95 is the most potent mask, unlike all other face masks. Its name means and shows that it is possible to block at least 95% of the tiny particles, 0.3 microns, which are the hardest to capture. Human hair is about 70 to 100 microns thick on average.
Make sure that between the edge of the mask and your skin there are no gaps. This includes a molded part of the nose on your face. N95 face filtering masks are made out of polyester and other single-use synthetic fibers.
Make sure that there are no holes between the edge of the mask and your skin. This involves a molded part of the face's nose. To check for air leakage and to ensure that masks are correctly sized and fit, most health care and other workers undergo annual fit controls.
Use of N95 masks
N95 would only allow users to have healthcare locations. Because people suffer from a shortage of several items (masks, gowns, glasses) in very challenging situations. In one subject, N95 marks are a shortage. The governments of all countries are trying to suggest for the only healthcare worker the reserve N95.
Make certain that there are no gaps between the edge of the mask and your skin. This includes a molded part of your face's nose. In order to monitor air leakage and to ensure that masks are properly sized and fit, several health care and other employees undergo annual fit controls. Since you have facial hair, you are not going to get a decent suit. For girls, they don't fit well either.
What makes N95 masks counterfeit?
N95 masks, also known as N95 Filtering Facepiece Respirators, which federal health agencies recommend that healthcare workers wear, are the masks that pose the greatest concern here.
The National Institute for Occupational Safety and Health (NIOSH) has certified these popular masks to ensure that at least 95% of the tiny airborne particles are filtered out. With a seal that forms around the nose and mouth, they are designed to have a close facial fit.
An N95 will exceed the level of protection provided by a surgical face mask if worn correctly. According to the U.S., defective masks offer lower protection levels, either because of the material or the facial fit and application, Administration of Food and Drugs.
How to tell counterfeit by The National Personal Protective Technology Laboratory (NPPTL)?
A number of news outlets report that counterfeit N95 respirators have been distributed to numerous hospitals and clinics across the nation as of early March. It is even more disturbing that some remain in use by unsuspecting suppliers. That is why knowing how to distinguish the real from the fake is essential.
The greater 'tell' is the use of headbands vs. ear loops. Headbands have NIOSH-approved respirators that provide a tighter fit and greater protection against COVID-19 air particles. On the packaging and/or within the user, all NIOSH-approved respirators bear an approval label.
Often, makes will also have one or more of the following:
Instead of a headband, ear loops
A missing approval number for testing and certification on the external face of the mask, on the exhalation valve (if any), or on the head straps
No labels on the respirator of the filtering facepiece .Misspellings, such as the acronym for NIOSH decorations of whatever nature.
Why are masks with valves counterfeit?
Masks containing tiny air valves have been outlawed by several cities, including San Francisco, as coronavirus facial coverings. For medical usage, they are also not recommended by the CDC. This is because the air that is inhaled by the wearer is filtered by these valves, but not the air that is exhaled, which could damage anyone if the wearer is contaminated.
As the product is mentioned by one online seller, "The valve works by opening when you exhale and closing when you inhale."
While there are NIOSH-approved N95 masks with valves available for those in the medical profession, when a sterile environment is required, federal health officials advise against wearing them.
Why are these masks available then?
Many of these masks are sold as a way to stop pollutants such as dust, smoke, and air pollution from being inhaled, as their specialty is filtering air that is being inhaled.Exhalation valve masks can be more desirable to consumers because they decrease resistance to exhalation, making it easier to breathe during use, which may benefit people with asthma. According to the CDC, some consumers often say the valves keep their faces cooler and reduce the accumulation of moisture within the masks. But if you are trying to avoid infecting those around you, this bit of comfort will come at a cost.
