N95 respirators are more effective than cloth and surgical masks because they filter out 95% of large and small particles, including bacteria and viruses, according to Cleveland Clinic. What does an N95 respirator protect you from during the COVID-19 pandemic? “The CDC acknowledges that the most widely-available respirator that meets international standards is the KN95,” Sachs says. (Another similar option, the KF94, follows South Korean standards.) N95s haven’t always been easy to find, however. However, only the N95 is approved for U.S.-based medical settings, while KN95 masks follow standards established in China. N95s are similar to KN95 masks in that they’re both respirators designed to filter out 95% of particles. The respirators have been worn in health care and industrial settings long before the pandemic, and they’re regulated by the CDC’s National Institute for Occupational Safety and Health (NIOSH). Because N95 respirators form a tight seal, the CDC notes that they can sometimes be harder to breathe through. The respirators are made of a web of polypropylene fibers and some feature a valve to make breathing easier. N95s often feature a “ cup, flat fold or duckbill shape,” with two straps that secure around the head and a wire-nose bridge that forms to your face, according to the CDC. What is an N95 respirator?Īn N95 respirator is a “ respiratory proactive device” that’s designed to fit tightly on your face and form a seal around the nose and mouth to filter out airborne particles. We've worked with doctors and PPE (personal protective equipment) experts for face mask guidance and we also sit on the ASTM committee that developed the industry standard for testing face coverings. The fiber scientists in the Good Housekeeping Institute Textiles Lab have been reviewing face masks since March 2020, starting with tutorials for DIY face coverings for both adults and kids before masks hit the mainstream market. Below, we're sharing what you should know about the best N95s, how they differ from other masks, and what to look for when shopping for face coverings. They should work to fit tightly across your nose, mouth and chin, as filtration depends on a tight seal. Sachs stresses that best way to know if a respirator is effective and well-designed is if they carry the NIOSH certification. Sachs says that there are classifications that shoppers can keep an eye out for when shopping for face coverings, set by ASTM International - and for N95s specifically, the CDC's National Institute of Occupational Safety and Health (otherwise called NIOSH) has been regulating production of N95 respirators over the pandemic. Now, however, shortages no longer exist - and the agency suggests individuals choose a disposable N95 in some situations.įinding an N95 mask can be difficult, though, as shoppers eagerly snap up supplies in retail locations as well as online - and because they're made differently than cloth masks, it can be equally tough to know which is best to buy. The reason likely stems from the early days of the pandemic when the CDC suggested that the public forgo the N95 over concerns that shortages of the masks would prevent health care workers from accessing them. Many people are still wearing cloth and surgical masks, though. “The secure fit is especially important because other masks can have an air leak around the edges.” “In terms of features, the CDC says the N95 is ideal because they seal more tightly around the face and they filter up to 95% of particles in the air,” explains Lexie Sachs, Textiles Director within the Good Housekeeping Instituteand a member of ASTM International's committee for PPE. The N95 mask, typically worn by health care workers, is considered a gold standard for COVID-19 protection because it offers top-notch filtration. Masks have been part of our routine for over two years now, but many Americans may be confused about wearing respirators like the N95 after the Centers for Disease Control and Prevention (CDC) recently updated its guidance to suggest that N95s are most effective.
