A single-use respiratory device designed to achieve a very close fit. The ZYB -11- N95 Particulate Respirator Mask is a NOISH approved (NIOSH Approval Number: 84A-7877) respiratory protective device designed for secure facial fit and a very efficient 95% filtration rate of airborne particles. The 'N95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles. This mask was also specifically designed to maximize protection while improving comfort through an adjustable nose clip. It also allows for easy breathing and speaking without comprising filtration effectiveness.
