About this deal

Generally, if the air can find a way around the filter, a lot of it will. So, you can have an extremely effective filter material, but if the air isn’t forced through it, it’s not as effective.” As for the masks that came in just a percentage point or two below the standard, he said they can still be used. When it comes to respirators, the number associated with the model indicates the filtration efficacy. Both the KN95 and the KF94 mask come very close to the level of filtration found in an N95 mask—they’re simply different equivalents.

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. 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. KF94 masks almost always use ear loops with an adjustable nose piece and often come in the 3D boat-shape style, meaning the mask has three folds that pop-out into a boat-like form when you wear it. This tends to allow for a versatile fit across a variety of face shapes and sizes, and may also feel more breathable than other options because of the extra room inside the 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. 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.

Where Can I Get KF94 Masks?

Health Canada and the United States Food and Drug Administration had temporarily authorized the sale of some KN95 and KF94 respirators during the pandemic. However, even authorized respirators are not allowed to use the FDA logo. 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.

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. 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.KN95s are manufactured in China, with an equivalent standard set by the Chinese government. The CDC estimates, however, that about 60% of KN95s available in the US are counterfeit products that don’t meet NIOSH standards. Centers for Disease Control and Prevention. NIOSH-approved N95 particulate filtering facepiece respirators. It’s important to note that washing single-use masks with soap and water, or sanitising them with alcohol, significantly decreases how effectively they can filter particles.
