In accordance with national standards, anti-particulate respirators are divided into different types, protective masks are one of them, known as disposable masks, i.e., the body of the mask is made of filtering material, the product does not need to be replaced after the failure of the components, to be discarded as a whole. For the basic requirements of the product's protective performance and comfort, in general, there is no essential difference between China's standards and foreign mainstream standards (such as European and American standards).
On the filtration efficiency of particulate matter: the evaluation conditions and methods of the standards of various countries are equivalent, China's standards and U.S. standards are also on the filtration element to prevent oily particulate matter (typically, such as barbecue fumes) made a classification of the national standard GB2626-2006 KN class (and U.S. standards NIOSH N class equivalent) is not suitable for oily particulate matter, the KP class suitable for oily and non-oily particulate matter (and NIOSH P class equivalent), while the European standard is not categorized and is universal.
On the respirator overall leakage rate: China's standards and European standards have specific restrictive indicators, the test method is similar, are in the laboratory, by a real person wearing a respirator to test the leakage rate; the U.S. practice is different, in the certification of the product link, usually do not test the respirator leakage rate, the leakage control link is placed in the use of the site, because the United States has another mandatory law in the workplace if the need to use respiratory protection, and the use of respiratory protection in the workplace. The United States has another mandatory law, in the workplace if you need to use respiratory protection, the employer must give employees to do the suitability of respirators test (to control the level of leakage), to ensure that each employee to select the appropriate respirator for their own (it is possible to use more than one type of product in a workplace), to ensure that the respiratory protection of the effectiveness of the product. Since our government has regulations for imported respirators used in domestic workplaces, which must be tested and certified by domestic authorities in accordance with GB2626-2006 (Labor Safety Mark Certification,LA), products imported from the United States with the LA mark also meet our standard requirements in terms of leakage rate.
On the breathing resistance: China's standard and foreign standard indicators are the same.
Product identification, logo: this mainly refers to the certification standard information, product categories and efficiency level information, etc., according to different standards certified products in the identification of different content, the standards of various countries, in addition to the provision of this information in the product packaging, manuals, are to be reflected in the product's filtering elements, in the protective mask on the body, the national product must be labeled GB2626 -2006 and efficiency levels, such as KN95; U.S. certified products must be labeled NIOSH (abbreviation of the certification body) and filter efficiency levels, such as N95, and certification numbers, such as the 3M 8201 mask is TC-84A-0007, different products, the certification number will be different; European certified products must be labeled with the standard number EN149: 2001 and the efficiency level, such as FFP1 (80% efficiency), FFP2 (94% efficiency) or FFP3 (99% efficiency), and the code of the certifying body, e.g., 3M 8822 is labeled "CE 0086".
Thank you for your interest in 3M, and I wish you a happy life~
