Particles get trapped as they are forced to make twists and turns through the dense network of the material’s fibers, which are as thin as a single micron. N95 respirators work by filtering out particles thanks to the structure of their nonwoven material. It's also important to note that a face shield without a mask is equally able to spread the virus. The masks will provide the same protection for the wearer as an unvented mask, but the valve does not block viruses from coming out, which can enable someone unaware they are infected to spread the virus to others. It should also be noted that recent reports from Healthline and the CDC show that masks featuring valves or vents are more likely to spread infection. Medical N95s are single-use products regulated as class II products under the FDA (Food and Drug Administration) and NIOSH (the National Institute for Occupational Safety and Health). It’s important to note that not all N95 respirators are designed for medical applications some are manufactured for industrial use. Some N95s feature exhalation valves, which help the wearer to breathe more easily. N95s come in several different shapes, which can help healthcare workers with finding a model that better fits their faces, but they cannot provide a seal for beards. Legitimate surgical respirators are approved by both the FDA and NIOSH (the National Institute for Occupational Safety and Health). There are also N99 and N100 respirators (N100s stop at least 99.97% of particles from entering). ![]() Originally developed for industrial applications, N95 respirators are specialized masks that filter out at least 95% of particles above. For less high-risk situations, we also have a guide on the best cloth masks available, as well as the best surgical masks for home use. If you’re more interested in the production and testing of surgical masks, you can also check out our guide on how surgical masks are made. In this article, we’ll be covering the basics around manufacturing N95 respirators, including what they’re used for, how they’re made, and what testing methods are used on them. are dealing with shortages while treating COVID-19 infected patients. N95 respirators are one of the products most in demand as healthcare workers across the U.S. Air supplying respirators supply the user with clean air from a tank or other uncontaminated source (for example an SCBA). Air filtering respirators (such as an N95 respirator, or mask) stop contaminants, bacteria, and other matter from reaching your nose and mouth. ![]() ![]() There are two basic types of respirators: air filtering and air-supplying. ![]()
