Mask, Coronavirus, Particulate Respirator Type N95 OMPARING FACE MASK TYPES | Efficiency, approvals, identifying fakes, and recent research.

As more and more of us start to depend on face masks to help protect our health it’s. Crucial that we understand the basic difference in face mask types and have a knowledge of how to check for niosh and fda approval when it applies i’m, rachel walla, with ally safety, and over the past year i have developed a lot of content on face masks. The purpose of this video is to give you all that content shrunk down into a quick and easy to follow guide so that you have the information that you need to make the best choice on the face mask for you. So without further ado, let’s jump right into it. Music. The first step in choosing the best face mask, is understanding the different levels of protection in the different types. So today, we’re going to be focusing on the five most common types that you see out and about those are n95s kn95s, surgical, masks, cloth, face, masks and neck gaiters. Just a heads up. This video is sponsored by clinical supplies, a distributor that helps to bring quality american made n95s to you, along with a full range of ppe offerings at, be including a link to their website, as well as links to all the different sources that i used for Information for this video in the description below this is an example of an n95 respirator. One thing that’s important to note with this section is that there’s actually quite a few different styles of n95 respirators.

Some are molded, some are folded and others are vented. The first n95s were introduced in the 70s as industrial single use. Respirators n95s work by filtering particulate through tiny pores found in the fabric. The 95 in the name n95 means it filters out at least 95 percent of airborne particulate and aerosols it’s, designed to provide a seal and fit closely to the face. When n95s are used in workplace settings, they’re required to be fit tested to make sure the wearer gets a good fit and seal and can also handle the extra strain of breathing through a respirator. There are typically a small range of sizes in each model, such as small, medium and large. However, some may only have a standard size it’s. Also critical. To note here that for men you need to be clean shaven in order to get the best seal. N95S are approved by niosh as a respirator and must also be cleared by the food and drug administration to be substantially resistant to fluids, which mimic blood and other bodily fluids in testing. If they’re going to be used in medical settings, n95s are the gold standard because of the quality assurance and testing they have to go through to be approved by niosh as respirators to find out. If an n95 is approved, the product should have the tc number in the product description online on the box and somewhere on the product itself. You can check that approval on the niosh registry in the link below i’m, also going to be including a link to the fda registry as well.

In terms of use limitations, an n95 has to be properly worn and fit to get a good seal. You also need to make sure that they’re replaced as necessary, Music. This is a kn95 mask it’s, designed to provide a seal and to fit closely to the face. Kn95S are essentially the chinese version of an n95 and were designed to be used in industrial and medical environments like an n95. The filter performance is supposed to be greater than or equal to, 95 percent efficient. There are some variations in testing, but overall they have a lot of similarities in design. Other differences between n95 respirators and kn 95 masks are that kn95s often use the ear loop method, whereas n95 respirators use head straps either way. The design is intended to provide a seal similar to an n95 kn95s are not approved by niosh, and researchers have recently found that up to 70 of masks do not meet us standards for n95s. Although certain styles of an n95 may look very similar to a kn95 kn95s are not approved by niosh, so they won’t have the same level of quality assurance that you get with an n95 like an n95 kn95s must be properly fit and worn to get a good Seal in addition, due to reports finding that many imported kn95s are not as effective as n95s it’s best to only use kn95s outside of high risk areas, this is a surgical mask. The surgical mask is intended to provide a barrier to prevent the wearer from transferring large droplets and aerosols that may contain viruses and bacteria to one another by covering the wearer’s mouth and nose.

Surgical masks provide a modest amount of filtration to their wearer, but they’re not intended to be tight, fitting or provide a seal to be approved for use in medical environments. The fda approves those surgical masks that are found to be substantially resistant to blood and other bodily fluid splashes, and some also comply with astm consensus standards. However, this isn’t required surgical masks work best when everyone wears a mask by preventing their own aerosols and droplets from escaping. Overall, they can provide a nice balance of breathability and protection to the wearer. Next up, we have cloth face, masks which can vary hugely in style, and the level of protection provided to the wearer. The cloth face mask has a similar intended function as a surgical mask. They help to stop the spread of aerosols and droplets at the source, while providing some protection to the wearer filtering depends on the amount of layering and the tightness of the fabric weave of the materials used. Recent research from mit has suggested that multiple layers of high thread count, cotton or a hybrid of cotton and silk or flannel, can provide a good level of protection as far as fit they’re not intended to be tight, fitting or provide a seal. But do look for those that fit well around your face as far as testing and approvals go, there are none as far as use limitations, cloth face, masks can vary so broadly it’s hard to give it a single rule.

What i would say for this, though, is find a multi layer mask that provides a good balance of breathability and protection for you, as the wearer make sure that you’ve got a few layers of tight woven fabric. Next up we have neck gators. Originally gators were intended to be worn around the neck for warmth. They’Ve also been the source of some controversy. This year, a team of scientists from duke university unveiled a peer reviewed study in july of 2020, in which they observed that a single layer gator appeared to perform slightly worse than a no mask control group. They suggested that the porous fabric may actually be producing smaller respiratory droplets that can actually hang around in the air for longer making the risk of transmission worse. Since then, aerosol scientists have since conducted their own non peer, reviewed, gator experiments that show when a single layer, neck gaiter is doubled. The gator is effective at blocking a range of particle sizes. Gators are not intended to be tight, fitting or provide a seal, and as far as testing and approvals, there are none use limitations. Preliminary research shows that net gaiters should be doubled up if they’re going to be worn as virus protection Music. So those are the basics that you need to know about face masks. My suggestion would be to take a few minutes to think about the level of risk that you encounter on a day to day basis. Things like interacting with the general public, your ability to social distance and also your own health conditions, then try to decide on the best face mask for you.
