Covid-19 is not sufficiently protected by single-layer cloth masks

Experts in public health warn that single-layer cloth masks, which were popularized during the pandemic, do not offer enough protection against COVID-19, particularly when used to cover the face of the Omicron variant. However, it is better to have some face coverage than nothing.

COVID can be airborne so the quality of the mask is very important. A single-layer cloth mask does not protect against the Delta variant and the highly contagious Omicron variant. It is, therefore, crucial to upgrade our masks. Protective measures are not enough with a simple cloth mask.

It is not surprising that Google searches for “mask”, “N95”, and “particulate respirator type” are on the rise in 2021. The “where can I buy N95 mask?” search was among the 10 most searched “where can I buy” searches in the past year.

KN95 and KF94 masks should be worn whenever you are in enclosed spaces with other people, such as on planes or mass transit, or indoor celebrations like the upcoming New Year’s Eve parties. These masks provide the best filtration and are essential in this epidemic of a highly contagious variant.

Dr. Jerome Adams said that “we need to promote better high-quality masks all over the world because right now a one-layer cloth mask just doesn’t cut it against omicron.” More testing is needed. We need better masking.

The judge at Ghislaine Maxwell’s trial ordered that everyone present in Manhattan’s courthouse wear N95 masks, or masks of similar high quality, starting Monday. He also noted, “obviously we have the variant” to think about. Throughout the trial, jurors were wearing surgical or cloth masks.

New York City distributes 500,000 KN95 test kits and 1,000,000 KN95 masks to community-based organizations as a result of an increase in cases, which includes almost 50,000 Christmas Eve.

Bernie Sanders, a Vermont senator tweeted, “As we face rapidly spreading Omicron variants, we need to remember that not all masks are equal.”

Traps smaller particles

What makes “95” such a magic number? The Centers for Disease Control and Prevention (CDC), explains that N95 respirators, also known as “masks”, have been approved by the U.S. National Institute of Occupational Safety and Health. They filter at least 95% of all airborne particles.

KN95 masks look similar but are not certified the same. N95 is the American standard and KN95 is the Chinese standard. KN95 mask manufacturers can apply for an emergency use authorization (EUA), from the Food and Drug Administration (FDA), to use their products in healthcare settings. Several KN95 masks have already received EUA from the FDA.

The KF94 masks filter 94% of aerosol particles and meet the standards set by South Korea’s government. The FDA has not yet granted them EUA for use in health care settings.

While cloth masks are better at filtering large droplets of water, smaller particles and aerosols that could carry airborne viruses may still be able to pass through them. According to the CDC, cloth masks are better than wearing no mask at all. Multi-layered cloth masks can block between 50% and 70% of fine particles. The N95s can filter 95% of particles.

Experts suggest double-masking, with a three-ply fitted surgical mask and a cloth, to increase the effectiveness of your surgical or cloth masks. They recommended that everyone at least wear a three-ply surgical face mask.

There are many counterfeits

However, counterfeit N95/KN95 masks can be found online. The government has published a guide on how to spot real masks vs. fake NIOSH-approved masks. NIOSH also offers a list of N95 respirators that are approved and sold in some home improvement stores and drugstores.

Which type of masks is best for the COVID-19 new omicron?

Experts recommend that people wear a well-fitted, high-filtration mask-like N95 to protect themselves from the transmissible micron variant. This mask is commonly worn by health care workers in high-risk environments.

Health officials agree that the best masks cover your nose and mouth and are snug enough to fit comfortably on your face.

To prevent air from leaking out of the top, CDC recommends masks that have at least two layers and a nose wire. The CDC suggests that you hold your mask up so that you can check whether it blocks light. If it does, the fabric will filter out more particles. Experts recommend wearing two masks to provide extra protection.

What is the difference between N95 and KN95?

An N95 mask (filtering face piece respirator) is an FFR. An FFR is a negative pressure particulate respiratory device that has a filter in the mask. The mask is rated to remove at least 95% of the airborne particles it encounters. Masks are also designed to seal the face.

What certification the mask has is what makes the difference between an N95 or KN95 mask. Different masks have different names and approval sources based on their origin country. They are known as N95, R95, and P95 if they were made in the USA and have been certified by the National Institute for Occupational Safety and Health. They are known as FFP2 in Europe and China.

However, the CDC warns that 60% of US KN95 respirators are fake and do not comply with NIOSH standards.
