The Powecom KN95 personal respirator, which ships from stock directly from our California warehouse, is a respirator face mask made of a multi-layer filtration system of non-woven breathable fibers and is utilized globally. The Powecom KN95 is manufactured by Guangzhou Powecom Labor Insurance Supplies Co., LTD. The Powecom KN95, made to the new standard, will be the same size, shape and use the same production process. The improvement will be from the new melt-blown polypropylene cotton filter layer which will upgrade the breathability factor (respiratory resistance) of the mask. This new enhancement will help make it easier to breathe for the user while still offering filter efficiency greater than 95%.
