KF94 - Face Protective Mask for Adult (White) [Made in Korea] [20 Individually Packaged] KN FLAX Premium KF94 Certified Face Safety White Dust Mask for Adult [English Packing]

Product Information

UPDATE: This story was originally published in April 2021. As of December 2021, Public Health Agency of Canada guidance has changed. It now recommends wearing the best quality mask possible, including N95 and KN95 respirators.

Even if the N95s become more accessible, KF94 masks are preferred in general healthcare settings in Korea. The important factors when choosing a mask type are not only safety but also the comfort of wearing the mask, especially if prolonged wearing is needed. In a study on long-term use of N95, blood CO 2 levels of nurses became significantly elevated and many subjective symptoms, such as perceived exertion, dyspnea, headache, and lightheadedness also increased over time compared to beginning-of-shift baseline measures. 17 Over time, touching or non-fitted wearing of FFRs due to discomfort can be a major factor that hinders adequate respiratory protection of HCWs. Considering that the clip used in this study were originally designed to improve wearing comfort by relieving pain behind the ears, especially in prolonged wearing, the results indicate not only a more comfortable but also a safe way to use ear-loop-type KF94 masks. Dr. Advani told NPR, "When it comes to use in day-to-day activities, overall surgical masks and three-layered cloth masks perform pretty well." Dr. Parikh told POPSUGAR that you may want a "higher-filtration mask for higher-risk activities, like public transport or grocery shopping." She stressed that medical-grade masks should be reserved for patients with compromised immune systems, healthcare workers, and essential workers. "The general public should be fine with triple-layered [cloth] masks," she said. "What will protect most is distancing and avoiding large gatherings, especially indoors." KF94s are manufactured in South Korea to meet a regulated standard. The respirator stands for “Korean filter” with a 94% filtration rate. Should everyone use respirators? KF94 masks are a great option for people who have trouble finding a good KN95 fit or, like Chang, worry that most KN95s are counterfeit. They open up a bit like an envelope and sit slightly off the face, giving you more room to talk and breathe. In addition to being manufactured in South Korea and approved by the KFDA, these BOTN KF94 masks are featured on Collins’s public Google doc containing filtration results for the masks he has tested. In his testing, he found them to have a filtration efficiency of 99.2 percent. They are also the only mask Chang recommended by name. Like the LG Airwasher masks favored by Strategist senior vice-president of e-commerce Camilla Cho, BOTN masks come with special adjustable ear loops. Simply pull on the little front loops to adjust the tightness around your ears and cheeks. Each KF94 mask in the Project N95 shop has full MFDS approval in addition to undergoing our own comprehensive review to ensure proper chain of custody and supply.These masks—more commonly referred to as respirators in the medical realm—are more effective at filtering out particles in the air, prompting a growing number of experts and public health officials to recommend their use over cloth masks. For reference, a regular blue surgical mask has a filtration capacity of about 80 per cent, providing that it’s fitted to the face well without too much gaping at the sides. Vally agrees that the protection of P2 respirators is only useful if properly worn. “There’s no point in having that increased cost … if they’re not worn properly and they don’t actually work in the way they’re supposed to.”

Since the beginning of the pandemic, Park has been working to verify the authenticity and quality of N95-style respirators destined for hospitals. He has since shared his expertise and compiled tips on what average consumers can look for when buying these masks. When it comes to use in day-to-day activities, overall surgical masks and three-layered cloth masks perform pretty well," Advani says. As far as protection goes, masks with multiple layers will do you better in staving off potentially infectious particles than thin ones – and studies have shown that three layers is typically the sweet spot. KF94s are better than cloth masks in terms of filtration and protection from airborne viral particles — after all, they're medical-grade masks — but you can still wear cloth masks, which continue to be recommended for everyday use in the US. "To be clear, cloth masks do work, too, just to a lesser degree," Dr. Feigl-Ding said, especially when it comes to filtering your own viral particles (though there is growing evidence that even cloth masks can protect the wearer to a degree). But Sim believes P2 class respirators are less useful for the general public than in specific workplace settings such as hospitals. “They’re not designed for general use out in the community,” he said. “You need to be trained in how to use them, they need to be fit tested for them to perform at their proper level of protection, and they’re not really designed for taking on … [and] off.” But Advani doesn't think the KF94 is a game changer for how we should all approach mask strategy. "While there are minor differences, those differences are rather small in general," Advani says. "It's negligible."While some masks tested well below the 95 per cent filtration standard threshold, others failed by just a percentage point or two. So how much do the results matter? Proper Removal. That starts with how you take your respirator off, with clean hands and by the ear straps, so you don't touch the front, which may have accumulated some virus particles. The CDC provides easy-to-follow directions on the proper removal (and handling) of respirators. At this point, mask mandates and other COVID-19 mitigation policies in the United States are more or less nonexistent. But it’s also clear that COVID-19 itself isn’t going anywhere — as of late February, an average of 3,000 people were dying of COVID each week in the U.S. According to Dr. Bruce Y. Lee, professor of health policy and management at the CUNY Graduate School of Public Health, no significant scientific organization has declared the pandemic over. “Things are getting better, but we’re definitely not out of the pandemic yet. We’re in a transition period,” he says. Dr. Gregory Poland, infectious disease expert at the Mayo Clinic, said when a mask becomes wet from exhalation or sweat, its efficacy decreases and advised rotating masks by day. WHEN TO WEAR AN N95?

KN95s (masks claiming to meet Chinese standards) and KF94s (those claiming to meet South Korean standards) require similar filtration efficiency to N95s but not the same markings, and so they can be tougher to evaluate by sight. If you're telling me that you're riding the subway or you need to ride public transportation, or you're a teacher and you're working in an indoor classroom full of children that typically don't show signs and symptoms of COVID-19, then yes, I believe you should get the highest protection possible." What are some tips to avoid poor-quality or counterfeit respirator masks? The CDC says that "a respirator may be considered in certain situations and by certain people when greater protection is needed or desired." Some of the situations that call for a respirator include:Now add another player to the mix – the KF94. This mask has been getting increasing buzz these days, with at least one media outlet calling it a "highly protective" option to look into at a time when emerging coronavirus variants appear to be more contagious. You notice quality-control issues. A crooked nose-bridge wire, elastics that lose their stretch or detach easily—these shouldn’t be found on any of your masks. These issues affect the fit and consistency of the mask and wouldn’t pass muster for a reputable brand. On N95s Proper Storage. Once you've removed the mask from your face, you'll want to store it in a safe, clean space—not in your purse or in your car's rearview mirror. "Keep it away from anything you'll be touching," said Flinn. "Putting it in a paper bag, so it's covered and not getting mixed up with other things can help, along with helping it dry out." According to Dr. Pierre, a plastic food storage container works too, but only if you keep the lid slightly open to prevent condensation on the mask. A harder container can also help retain the structure of the mask.
