Masks can be generally divided into two categories, general masks and protective masks. General masks are mainly used to keep warm and windproof, and protective masks are mainly used to protect various particles. According to the different protection objects, protective masks can be divided into disposable masks, daily protective masks, medical masks, industrial masks, coal mine masks, etc.

There are many kinds of mask materials, such as cotton, cashmere, cashmere and so on, which play a role in keeping warm; most of the masks with particulate matter protection use non-woven filter materials. Some manufacturers, in order to keep warm, beautiful and protective effects, use various colors of fabrics to wrap the mask, and clip the non-woven fabric with filtering effect in the middle.

In terms of material manufacturing and processing technology, each company has its own characteristics. In terms of the production of filter materials, melt blown or electrospinning methods are mostly used. Some manufacturers can add charges on the filter materials through electret process, so as to improve the adsorption capacity of the materials without increasing the thickness and resistance of the materials.

All protective masks of Hebei Baota Medical Equipment Co., Ltd. are processed in strict accordance with the pharmaceutical industry standards to ensure that the bacterial filtration efficiency BFE is greater than or equal to 95%. The workshop is equipped with instrument room, ventilation resistance tester, synthetic blood penetration tester, filtration efficiency tester and other testing instruments to conduct a comprehensive inspection on the protective masks to ensure the quality of products.
