Why choose kf94 masks at Kshops.com.au?
With how contagious the Omicron variant and BA.2 are, health officials are no longer recommending reusable fabric masks instead they suggest using disposable masks that offer higher filtration such as KN95, KF94, and N95 masks “Even though this variant may be milder, it spreads much more easily and in unvaccinated and high-risk individuals can still be very dangerous,” says Dr. Purvi Parikh, an immunologist with NYU Langone Health, told NYmag.
“KF94s have four layers of filtration against a typical three-layer cloth mask, but are cheaper, more breathable and more comfortable against sensitive skin than a lot of N95s. KF94s seem to be more readily available than the N95, less expensive and easier to use for many people,” Stephen Morse, an epidemiology professor at Columbia University, was quoted by National Public Radio U.S.A as saying.
“These are basically N95 masks, just from South Korea,” infectious disease expert Amesh A. Adalja, MD, senior scholar at the Johns Hopkins Center for Health Security is quoted as saying, and along with N95s and (genuine) KN95s, “these masks are the best types of masks to protect against COVID-19,” Thomas Russo, M.D., professor and chief of infectious disease at the University at Buffalo in New York, tells Health. A limited study published last year showed that the KF94 was comparable to the N95 in blocking SARS-CoV-2 particles.
Fit: Many people like Kf94 masks because the tentlike shape creates an extra gap between your mouth and the mask compared to other respirators. Lauren Ro a writer for NYmag prefers KF94 masks as they “are better for a more customizable fit.” and another staffer Camilla Cho was quoted as saying “They are just much easier to breathe in since there’s that space between your nose and mouth and the inside of the mask”
A feature that both N95 masks and KF94s have is an adjustable piece of plastic that can be squeezed to get a snug fit over your nose. They also have side flaps which match the shape of your face. “These (flaps) help close the gaps around the face and limit unfiltered air entry,” Sara Andrabi, MD, assistant professor of emergency medicine at Baylor College of Medicine says.
Benefits: good way to know if you are getting legitimate KF94s is by making sure they are made in South Korea. For Chinese made KN95s, it can be a little more difficult since “there is no regulatory agency that actually ensures that a manufacturer actually meets the KN95 standard,” according to Michael Chang, MD, an assistant professor of pediatrics with McGovern Medical School at UTHealth Houston.
“In general, don’t buy random brands from Amazon/eBay,” says Aaron Collins, a mechanical engineer with a background in aerosol science who has spent the pandemic testing many masks he purchased online, suggesting only buying from reputable sources. Collins says he really trusts the stringent testing process for KF94 masks. “In South Korea, if you put a KF94 stamp on your masks and don’t meet the standards, the government will fine you heavily,” he says. “I like these masks because of the quality system in place.”
