In some settings masks manufactured for purposes such as construction or manufacturing are available. These masks are often described as reusable half face masks, reusable full face masks or dust filtration masks and are designed for preventing the transmission of chemicals, solvents, dust and other particles. They normally have filters that are attached on the side which are replaceable. Some of these masks are effective for use against SARS-CoV-2 but use of these masks in health care settings should always be verified by the manufacturer and national guidelines. The use of these types of masks is not recommended in community settings because they are not available at scale, they are visually quite scary looking and may create unnecessary fear, and because they are produced at a range of qualities.
