PM2.5 masks marked on the market are classified by materials, including ordinary gauze masks, ordinary medical masks, N95 masks, and masks authorized and certified by the "PM2.5 Protective Masks" group standard. The mask material is divided into three layers, the outermost layer: high-density antibacterial and environmentally friendly reactive dye fabric (cotton polyester fiber), the second layer: PM2.5 protective layer, warm and breathable polypropylene fiber (translucent, pure white), replacement Floor.
3M dust masks have activated carbon in the interlayer to prevent dust, bacteria, formaldehyde and secondhand smoke.
The non-woven composite mask adopts electrostatic composite fiber non-woven fabric, which can filter PM2.5 particles. The medical protective mask adopts an ergonomic structure, three layers of non-woven fabric, and a high filter layer of superfine fibers. The use of antibacterial filter paper can effectively block fine dust, thereby effectively reducing bacterial invasion. There is a moisture-proof layer in the middle of the mask, which has the characteristics of acid resistance, alkali resistance, and temperature resistance. It has good skin affinity and good comfort. The strong electrostatic treatment filter cloth can filter bacteria.
The mask with breathing valve is made of N95 filter material, non-woven material and activated carbon material. It can isolate extremely fine dust and is suitable for various dusty operating environments, public places and various humid environments. It can effectively block and block the particles that degrade carcinogens, such as nitrogen compounds and various industrial dusts.
The MEO anti-smoke mask is made of lanolin specially cultivated in New Zealand. It is a high-efficiency electrostatic filter material that can electrostatically adsorb 98% of the fine particles (ie PM0.1) with a diameter greater than 0.1m in the air. The air permeability of the wool filter is more than 5 times that of similar products on the market, which can reduce the accumulation of heat and moisture and make breathing more smooth. The three-dimensional cup cover design increases the internal space and is more comfortable to wear.
