Introduction of Green Shield and 3m
All the anti-particulate mask products sold by 3M in China, whether imported or made in China, have obtained the labor safety certification (LA certification) of China, and have reliable protective performance. 3M company's proprietary high-efficiency cotton filter ensures the filtration efficiency, and at the same time, the breathing resistance is low, which makes the wearer breathe more easily.
Green shield mask is a new generation of antibacterial and dustproof mask developed by Shanghai Xingnuo Kanglun Technology. At present, it has the patent authorization of domestic PM2.5 mask, and its patented PM2.5 technology can prevent particles with particle size less than or equal to 2.5 microns.
The difference between Green Shield and 3m
3m is an international brand, and the overall product quality and quality are relatively good. However, 3m low-end household masks have always had a common problem, that is, the odor is too heavy, which makes people dizzy. I don't know why 3m Company hasn't solved it.
Green Shield is an online brand, with many advertisements and average product quality. In fact, many of them can't meet the national standards, and there were also quality problems of 3 15 exposure before. Compared with 3m, it is still not the same level. A good brand must first have a good product, otherwise the final product, no matter how much publicity it does, will be of poor quality and useless, and will be eliminated by the market sooner or later. Bottle technology mask is carefully made for each mask, and the real good product itself is marketing.
Which is better, Green Shield or 3m?
They're all fine. The effect of 3M is better, and it can't be reused at that time, which is not only expensive, but also can only be used once. Green Shield is a cotton mask. You can change the filter element, and then change the filter element every day, which is more economical. Both can be considered. You can choose according to your actual needs, and choosing the product that suits you is the best.
