Medical equipment masks are divided into: 1 for civil use, 2 for medical use and 3 for medical surgery
1 for civil use: the first type is disposable mask without disinfection, and the anti-virus rate is 0%
The second type of sterilized mask is called disposable sterile mask, with an anti-virus rate of 45%
The third kind of N95 has 95% anti-virus rate
2 medical class: the anti-virus rate of disposable medical mask is 85% or 90%, N90 or Kn90 or kf94
3. Medical surgery: the anti-virus rate of medical surgery is 95%. Medical surgical mask is a recognized product for cross infection prevention in operating room.

The new EU regulation (EU) 2016 / 425 has been implemented. Respirators belong to the three categories of products "substances and mixtures endangering health". They must apply for approval according to module B + module C / D, similar to Section A / B, Chapter 11, EC type inspection, Chapter 10, Directive 89 / 686 / EEC of the old regulation.
With the growing awareness of the hazards of PM2.5, the protection of PM2.5 is also increasing, and the use of masks is increasing. The state has also updated gb2626-2016 respiratory protective equipment. It's a very big business opportunity for businesses. Here's a brief talk about the requirements of major countries in the world for mask certification and testing. Gb2626-2006 according to the leakage rate of the mask and the filtering efficiency of the mask itself, the mask is divided into three grades: 90 (Kn90, kp90), 95 (kn95, kp95) and 100 (kn100, kp100). This standard is closer to the international standard, such as the European Union standard EN 149, NIOSH certified mask in the United States, as 1716 in Australia and js-t-8151 in Japan
Products sold in the EU market must obtain CE certification. From 2019, the new regulation (EU) 2016 / 425 will be enforced. All masks exported to the EU must obtain CE certification under the requirements of the new regulation. EU standards for common respiratory products are as follows:
BS EN 149: 2001 filtering half masks to protect against particles
BS EN 136: 1998 full face masks - class 1, 2, or3 full face masks - class 1, 2 or 3.
BS EN 140: 1999 half / quarter masks
BS EN 14387: 2006 gas filters & combined filters
BS EN 143: 2000 particle filters
NIOSH classifies its certified particulate respirators into 9 categories according to Department of health and human services (HHS) Regulation 42 CFR Part 84. The specific certification is operated by npptl (National Personal Protective Technology Laboratory) under NIOSH.
According to the filtering characteristics of the middle filter screen of the mask, it can be divided into the following three types:
Grade 100: the minimum filtration efficiency is 99.97%.
Grade 99: indicates that the minimum filtration efficiency is 99%.
Grade 95: indicates a minimum filtration efficiency of 95%.
According to the minimum filtering efficiency of the filter screen material, the mask can be divided into the following three grades:
N series: n stands for not resistant to oil, which can be used to protect non oily suspension particles.
P Series: P stands for oil proof, which can be used to protect non oil and oily suspended particles.
R Series: R stands for resistant to oil, which can be used to protect non oily and oily suspension particles.
N95 respirator is one of nine kinds of particle respirators certified by NIOSH (National Institute of occupational safety and health). "N" means the particles that are not suitable for oil (the oil smoke produced by cooking is the oil particles, while the droplets produced by people's talking or coughing are not oil particles); "95" means that under the detection conditions specified in NIOSH standard, the filtration efficiency reaches 95%. N95 is not a specific product name. As long as the product meets the N95 standard and passes the NIOSH review, it can be called "N95 mask".
As / NZS 1716:2012 is the respiratory protection device standard in Australia and New Zealand. Manufacturing processes and tests must be in accordance with this specification. This standard specifies the procedures and materials that must be used in the manufacturing process of particle respirators, as well as the determined test and performance results to ensure their use safety.
When the safety of life depends on PPE products, benchmark certification will provide you with real confidence. As a testing and certification agency, we believe that we can certify and test our laboratory products according to the industry recognized standards. From safety glasses to complex respiratory and fire-fighting equipment, we help manufacturers prove that safety is essential and that products have been proven to meet agreed high standards.
