ABSTRACT: The key aim of this article is to provide a description of the structure and uses of N95 mask that is necessary to advance Personal Protective Equipment ( PPE) during this COVID19 pandemic. Examples of personal safety gear designed to shield the user from infectious debris and from fluids contaminating the skin include the N95 respirators and medical masks (skin covers). A commercially available N95 respirator needs a suit factor of one hundred within the work-place to be deemed adequate. While we did not subjectively locate the respiration function needed with the prototype masks to vary from that necessary with a standard N95 filtering face device, this mask should not be used by people with respiratory risk of any sort. Although testers wear the masks easily for an hour, at any point in strenuous work or adverse environmental environments we can not think about their usefulness. This review offers detailed knowledge and appreciation of the structure, applications of N95 masks and, in turn, the advantages of N95 masks over other forms of surgical masks. Limitation and prospective range of the research were also addressed, as this subject is necessary to advance PPE in this COVID19 pandemic. This research contributes greatly to learning about the composition and uses of N 95 masks, and also helps to educate and make the general public informed of the critical role of N 95 masks during this pandemic assault.
