    A N95 mask or N95 protective mask is a particulate filtering face-piece respirator that meets the N95 standard of the US National Institute of Occupational Safety and Health (NIOSH) air filtration rating, which means it filters at least 95% of The particles in the air are not resistant to oily P95. It is the most common particle filtering face mask respirator. This is an example of a mechanical filtering gas mask. It provides protection against particulates, but not gas or vapor.

    N95 gas masks are functionally equivalent to certain gas masks that are not regulated within the jurisdiction of the United States, such as FFP2 gas masks in the European Union and KN95 gas masks in China. However, slightly different criteria are used to prove its performance, such as filter efficiency, test reagents and flow rate, and allowable pressure drop.

    N95 masks require fine mesh synthetic polymer fibers, also known as nonwoven polypropylene fibers [5], which are produced through a process called meltblowing, which forms an internal filter layer for filtering out harmful particles .n95 masks for sale.

    During the 2019-20 coronavirus pandemic, the supply of masks was in short supply, leading to price snapping and ho-products, often resulting in the confiscation of masks. The production of N95 masks is restricted because the supply of non-woven polypropylene fabric (used as the main filter) is restricted and exports from China are stopped. China controls 50% of the global mask production and faces its own coronavirus epidemic. It uses all its production for domestic use and only allows exports through humanitarian aid allocated by the government.

    In March 2020, President Donald Trump applied the National Defense Production Act to 3M Corporation of the United States, which allowed the Federal Emergency Management Agency to obtain the required number of N95 respirators from 3M Corporation. White House trade adviser Peter Navarro said that there are concerns that 3M products have not entered the US market. 3M replied that it did not change the price it charged and could not control the price charged by its dealers or retailers. There is a serious shortage of masks in the United States.

    As more and more countries restrict the export of N95 masks, British Columbia’s Novo Textiles plans to become Canada’s first manufacturer . Quebec ’s AMD Medicom also plans to become Canada ’s second N95 mask manufacturer and has signed a contract with the Canadian government .
