The Biden Administration has releasedIndividuals are required to wear masks on federal property, and are encouraging all Americans to wear them in public . Face coverings are Renewed questions about what types of masks provide the best protection against aircraft, trains, buses and airports , As well as where to find them.
The “100 Days Masking Challenge” aims to stop the rapid spread of coronaviruses, which have already claimed the lives of more than 400,000 Americans. Indeed, a study published on January 19 in the Lancet Digital Health Journal Studies found that wearing masks in the United States by just 10% would significantly limit the transmission of coronovirus.
According to medical experts, wearing a mask is even more effective when properly and efficiently filtering aerosol particles.
“In addition to filtration, fit is the most important factor that curbs educational health content for the general public,” said Devabhaktuni Sri Krishna, founder of the global health platform Patiao.
“Even if you’re wearing a high-quality mask, if it doesn’t make contact with your face, it’s going to leak around. The best masks have a very solid, tight seal, so that air doesn’t leak. Be. Effectively, less fit equals less filtration, “said Sri Krishna.
Megan Ranney, an emergency physician at Rhode Island Hospital, ranked the commonly available mask options from the most effective to the least effective, noting that generally, any kind of face covering is better than none.
N95s provide the most filtration according to R95, followed by the so-called KN95 masks. The regular surgical mask is the next best option, followed by a double-layer cloth mask with a filter worn between the two layers. He stated that double-layer and single-layer cloth masks without filters are the least efficient.
“Whenever you take a step, you’re going to get some protection. The things that make them better, within the fabric or the homemade facade, include two layers of fabric, with one in between the two layers. The vacuum bag is a filter., And the fabric must be tightly woven, ”said Ranne.
Embed Tweet Sunday., Who was the director of the Centers for Disease Control and Prevention from 2009 to 2017, appreciated Runni’s advice
“N95 masks are the most protective masks, followed by three-ply surgical masks, then fabric masks. A fabric mask is a lot better than a mask without, but we may need to advance our mask game when contagious.Start spreading widely, ”he said.
N95 – King of all masks
An N95 approval rating by the National Institute for Occupational Safety and Health means that a mask has been rigorously tested and verified by the federal government and filters out at least 95% of airborne particles.
NIOSH maintains a list of brand approved respirators. Because N95-approved masks remain in short supply, however, experts still recommend that they be used only by health care providers.
“I usually ask the public not to buy N95s because the authentic ones are still in short supply for health care workers,” Ranney said.
Proper fit, meanwhile, which is also the key, is difficult for the laypers to obtain.
“Within health care, before we are allowed to care for patients in N95 or equivalent masks, we must undergo a fit test where they move our head around and see if there is a bitter spray mask. Meets through. An average. Rainey said, “A member of the public cannot conduct a fit test, so we are hesitant to recommend that the public wear the N95.”
Brian Wollin, whose work as a chiropractor has slowed since the onset of the epidemic, is selling his company Protective Health Gear, a NIOSH-approved N95 mask in Newton, New Jersey. Initially, their goal was to help hospitals meet their mask needs. He is now appealing to the general public to breathe.
“We think it’s very important to sell it to the general public now. I think if everyone on the planet wears one of these things for 30 days, we will take care of that.”
He acknowledged the importance of fit testing in health care settings but stressed that regular individuals can easily shield masks of protective health gear to create a tight seal on their face. A box of 50 respirators costs $ 199 which is available at ProteanshellGear.com.
While the NIOSH-approved N95 masks are one of the most rigorous tests for various factors including filtration, shortness of breath, and durability, there are other effective options suitable for general use when the N95 is not available.
Sri Krishna recommends reusable elastomeric masks, which are more durable and cost-effective than disposable N95s.
Elastomeric masks provide a high level of respiratory protection, and can be combined with disposable filters. The masks themselves are made of flexible material like rubber and can be adjusted to fit perfectly on the face of the wearer.
A 2020 study published in the Journal of the American College of Surgeons found that health care workers who swapped disposable N95 masks for elastomeric diversity – paired with a P100 filter – wore any N95 mask Did not return
The study’s lead author, Dr. “Our physicians were very comfortable with the fit, knowing that it was not equivalent to a better amount of protection, and intended to reuse these masks,” Sricharan Chalakonda said in a statement.
The elastomeric mask shell is sold separately with a filter. Sri Krishna advised to tie the mask with the P95 filter as opposed to the P100 filter for easier breathing. Another plus for elastomeric masks: they are relatively easy to find. A 3M version is available on Amazon for $ 15, as P95 Particulate Filters – sold separately.
The Centers for Disease Control and Prevention also approves the use of elastomeric masks, calling them “equivalent protection” for N95 masks.
KN95s from China
KN95 masks look similar to N95 masks but meet completely different standards. While N95 masks are NIOSH-certified, KN95 masks meet Chinese government standards for certification.
Given that the quality of KN95 masks is wildly inconsistent, there are plenty of them in the US, especially those sold on platforms such as eBay and Amazon. A September report by ECRI, a nonprofit health care safety organization, found that up to 70% of KN95 masks did not meet US standards of effectiveness. In other words, they did not filter 95% of the aerosol particulate, as their name suggests.
Of course, average consumers are unlikely to have time and equipment to inspect masks.
“In health care we generally avoid KN95s at this point,” said ER physician Runne. Ranney is the co-founder of GetUsPPE.org, a site that provides donated PPE to frontline workers and under-resourced communities.
Ranney said her organization received batches of donated KN95s, many of which failed the group’s inspection process. “Clothes masks that fit really well and have a filter between the layers are going to be more reliable,” she said.
The Food and Drug Administration however provides a list of KN95 masks authorized for emergency use by healthcare professionals.
Among them are the KN95 masks from Chengde Technology, priced at $ 15 for a pack of 10.. They are available here.
Powecom KN95 masks are also approved by the FDA for emergency use. Office Depot sells 10-packs for $ 10.
KF94s from South Korea
KF94 masks, which meet standards set by the South Korean government, are generally seen as more consistent than KN95 from China, but are still not fully approved for use in healthcare settings in the US
Korean cosmetics company B Healthy sells KF94 masks imported from South Korea from a wide variety of manufacturers. All products sold by the company online meet South Korean standards, and some are also approved for use in Europe.
In a study by the National Center for Biotechnology Information comparing the effectiveness of surgical N95 and KF 94 masks, both types of masks were found to be equally effective.
Of course, given the lack of the N95 mask, fakes abound. According to the CDC, masks with fake N95 respirator signs, no markings or approval numbers on the face piece, and no NIOSH marks are included. Other red flags include decorative add-ons such as sequins and approval claims for children. Packaging claims that a product can also be “legitimate” or “genuine” indicating that it is not in accordance with the CDC.
