These materials, such as polypropylene, are usually non-woven and sometimes carry an electrostatic charge, which attracts these particles and traps them in the filter. N95, KN95, and KF94 masks all have high filtration efficiency, meaning the materials they are made of, which usually consist of several layers, are extremely effective at filtering out tiny particles. Things to consider before buying a high-filtration mask Filtration We evaluated the options based on their fit and comfort, while also making sure the masks didn’t leave any gap that allowed exhalations to escape-and that they were easy to put on and to wear for long periods of time. We also tested four ways to make a surgical mask more effective. In addition, we consulted scientific studies about general mask use and the effectiveness of high-filtration models, though few formal studies have compared different brands.īased on our expert source’s experiences with masks and filtration data, we selected eight adult masks and four children’s masks to try out ourselves. We also referenced the facewear-centric YouTube channel of self-styled “mask nerd” Aaron Collins-a mechanical engineer with a background in aerosols who’s been testing the masks on his and compiling the results into a publicly available spreadsheet-as well as the testing by mask company Armbrust. To learn the science behind high-filtration masks, we talked to three engineers with expertise in aerosols, three doctors in areas like infectious diseases and emergency medicine, a nurse with expertise in disease prevention, and a pediatrician (for the wee faces). How we chose the best high-filtration masks Best mask for kids: BOTN Child Fit KF94.Best mask to make a statement: MaskLab KF-style.Best KN95 mask: Powecom KN95 (ear loop version).Most comfortable N95 mask: Kimberly-Clark PROFESSIONAL N95 Pouch Respirator (a.k.a., the “duckbill”).But how do you know which of these masks will provide the best protection? Here’s what you need to know to pick the right one. Anyone can also supplement the freebies with readily available and relatively inexpensive options, as well. In January 2022, the US government started a program giving out free N95s at pharmacies. These masks-which bare standards like N95, KN95, and KF94-will provide you with the highest level of protection from COVID-19. As the highly contagious Omicron variant dominated virus cases in the US and around the world, the CDC leaned on recommendations for switching to a high-filtration mask (also called a respirator). Since the disease’s earliest days, cloth masks offered a convenient and stylish way to don the essential accessory, but most common textiles aren’t great at filtering out the tiniest droplets, called aerosols, that might carry the SARS-Cov-2, the virus that causes COVID-19. Two years (and counting) into the COVID-19 pandemic, most of us have gotten used to wearing a face mask. ![]()
