Whether doing day-to-day work or spending time on a special weekend project, Dr. Talbot’s KN95 face masks have got you covered. The KN95 face masks have a 4-layer filter that stays breathable while still blocking particulate matter. Dr. Talbot’s KN95 face masks fully cover your nose and mouth, providing more thorough protection from dust and pollen. The built-in, bendable nose clip makes it easy to adjust the mask to fit your face for the most comfortable wear and the best coverage. Dr. Talbot's KN95 face masks can be used indoors and outdoors and are intended for single-use wear.
