Product Information

Surgical masks, like P2/N95 respirators, are made from three layers of meltblown polypropylene, and contain an electrostatic charge that traps particles being breathed in or out. Below, is a list of N95, KN95, KF94, surgical-style and cloth masks (which, again, are recommended when doubling up). While CNET hasn't expressly "tested" most of these masks, they conform to the expert mask recommendations above. 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 imported equivalents include the KN95 respirator, which meets the Chinese standard of 95 per cent filtration efficiency and the KF94, which meets the Korean standard of 94 per cent filtration efficiency.These companies, he said, are more likely to have a relationship with a reputable supplier. Some manufacturers also sell directly to consumers, including Canadian companies that have recently been ramping up production of N95-style respirators. 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? 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.

There’s no branding. You should see the name of the company or logo right on the mask, whether it’s an N95, KN95, or a KF94. “Commercially speaking, companies are in the mask business to build brand loyalty and generate sales,” said Anne Miller, executive director of Project N95, a nonprofit clearinghouse that vets and sells masks. A blank mask runs counter to that goal. (Athough the vast majority of masks we tested included branding right on the mask, there can always be exceptions, particularly on masks for kids.) They matter for [health-care] workers and to a similar extent they matter for members of the public who have very specific susceptibilities where they need to go that extra distance to [protect] themselves from people in the environment." Should I be wearing a KN95 or KF94 respirator? In other words, she says, there's no need to go out and buy up medical-grade KF94s — especially, she says, since some wearers have said the South Korean mask is less comfortable or harder to breathe out of than the alternatives. The KF94 masks use ear loops instead of an elastic head-band as in N95s. In our pilot tests, most of KF94 masks failed to fit properly when undergoing the occupational safety and health administration (OSHA) fit test protocol. The general fitting applied through ear loops may be weaker than a head-band, and this can be a severe concern that hinders mask fitting. Some people who wear ear-loop masks apply a mask clip that connects the ear loops behind the head to reduce pain around the ears. The use of this clip may also increase tension on the entire mask through additional tension on the ear loops; thus, it was reasoned that using a clip may improve the face seal of ear-loop-type masks. Find the mask where no matter what you’re doing the elastics are tight and it’s not letting any air escape around the edges. Otherwise, you’re really just wearing it for optics.

What Is the Difference Between the KF94 Mask and N95 Mask?

It’s very important that with Omicron – it’s just so transmissible – that people wear the best quality mask they can,” said Dr Karina Powers, an occupational health physician in Western Australia. As for the masks that came in just a percentage point or two below the standard, he said they can still be used.

For people who want to be safe, in other words, they want to reduce the number of particles they breathe in, they should really pay attention to how their mask fits their face,” he said, noting this goes for both medical-grade masks and cloth masks. The CDC said masks are meant for single-use but can be used more than once when there is a shortage. The agency says N95s should not be used more than 5 times. 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. Three masks from each brand were tested at a lab at the University of Toronto's Dalla Lana School of Public Health to see if they meet their filtration efficiency claims. Half failed. 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.”KF94 masks are an excellent high-filtration option for a wide range of the general population. Because the KF94 standard was meant for public use, the masks are consumer friendly and available in many different sizes (including for very young children), styles, patterns, and colors. If you’re in a higher risk situation, you want to be wearing the best mask you possibly can,” he said. P2, N95, KN95, KF94 respirators – what is the difference? We chose respirators that are relatively easy to find, have passed filtration testing, and have received any relevant stamps of approval from government agencies. N95s, for example, must be approved by NIOSH, as well as the FDA if they're for medical use. For KN95s, we looked for masks from manufacturers that previously received emergency approval from the FDA. For KF94s, we looked for masks that have been tested and approved in South Korea. However, surgical masks were initially designed for “ source control” – worn by doctors and nurses to minimise the risk of contaminating a surgical area or infecting their patients.

Sim is also concerned about potential supply issues if there is a rush on respirators by the general public. “I think that could cause a squeeze in the health and aged care sector.” 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. Hoption Cann says it should be noted that many masks that are sold as KN95 or KF94, when tested, fail to meet their advertised filtration efficacy. National Personal Protective Technology Laboratory (NPPTL). Counterfeit respirators/misrepresentation of NIOSH approval. Plus your good-ol' N95 — the medical-caliber mask that is still in short supply for health workers.Powers says people in the general community can re-use P2 respirators. “You can drop your risk of transmission of Omicron by simply wearing the respirator and putting it in the sun, drying it out. You can keep using it … until the elastic breaks.”
