At present, the types of masks circulating in the market are generally divided into air filter masks and air supply masks, and air filter masks are more widely used, such as dust masks, haze masks, medical masks, etc. At home and abroad, for various types of masks have established corresponding standards to regulate the mask market.Most of the protective filter mask standards implemented in China are mandatory product standards, and their test items are compared. Among them, the ventilation resistance and air permeability of medical masks are conventionally required performance. JNMTextile Testing Instruments, Testing Equipment Manufacturer
