What's the difference between 3m mask 900 1 and 9002?

Both 3M900 1 and 3M9002 dust masks are industrial dust masks produced by 3M Company, which meet the standard of GB2626-2006KN90 in China. There is no difference between the two masks in terms of materials. The only difference between them is that the two masks are worn in different ways.

3M 900 1 dust mask is an ear strap, and 3M9002 dust mask is a headband. According to the traditional way of wearing masks in China, 900 1 dust mask is more suitable for us to buy and wear. If people need to wear it for a long time, such as traffic police and others who need to be exposed for a long time, it is best to use a headband-type 9002 dust mask, which can avoid the pressure on the ears and be more comfortable.

At present, 3M900 1 on the market is divided into paperback and hardcover. 3M9002 is also divided into paperback and hardcover. Paperback, also known as environmental protection, is 50 dust masks packed in a bag. Hardcover is two dust masks packed in a bag. You can buy the dust mask you want according to your own needs. When buying, you should distinguish between the way you want to wear and the packaging form, so you can choose the fine and simple 900 1 or 9002.

In fact, 3M900 1 and 9002 dust masks have other styles. That is, 900 1V and 9002V v. They are the same as 900 1 and 9002 in material and even packaging form, but they are quite different from 900 1 and 9002 dust masks. 900 1V and 9002V are dust masks with breathing valves. The application of breathing valve has become the essential difference between 900 1 and 9002 and 900 1V and 9002V. Breathing valve, through its special structure, can exhaust exhaled moist gas and prevent unfiltered air from entering the mask. The application of breathing valve can not only reduce the respiratory resistance, but also reduce the humidity in the mask.
