1. Know the packaging

The first time you get a 3M mask, you should check the outer packaging box of the mask. Real 3M mask packaging has text or English descriptions on all four sides. Take a look. Product packaging, the fake 3M mask carton is relatively thin, pay attention to the bottom of the carton. Secondly, in order to make it easier for users to distinguish authenticity from fake ones, 3M China generally uses color-changing anti-counterfeiting labels to seal the packaging boxes of 3M masks.

When the line of sight is perpendicular to the anti-counterfeiting label, the colors of the label from left to right are colorless, black, and red respectively; when the line of sight is tilted to a certain angle with the anti-counterfeiting label, the colorless becomes blue-green, and The red and black on the right merge into one color. If there is no discoloration on the anti-counterfeiting label, it means it is a fake 3M mask.

2. Identify the shape

The shape of the real 3m dust mask is designed in the shape of a face, which makes it easier for the wearer to wear it and is more comfortable. There are not too many gaps exposed, and the face shape is smaller than The imitation is much wider; while the imitation is round, does not have a design that fits the human face, and is not tight when worn.

3. Smell the smell

Real 3M masks are non-toxic, odorless and non-allergenic. If there is an irritating smell, it must be fake. However, some customers have reported why there is still some odor after opening the package after confirming that it is a real 3M mask? This is because the odor of 3M masks comes from the mask materials, such as the rubber material of the headband and the adhesive of the nose clip. If you find any odor, open the package and let the 3M mask be placed in a clean and ventilated environment for a period of time before the odor dissipates before use.

4. Touch the metal piece of the mask

The metal nose clip on the real 3M mask adheres very tightly to the surface of the mask. No matter how you press the metal piece with your hand, the genuine 3M mask will not The cracked one is close to the fabric and there is no space; the fake 3M mask will come apart when the metal piece is pressed, revealing a large space. If a mask becomes loose or has gaps when you pull it with your hands, it is definitely a fake.

5. Rubbing the printed words

The real 3M mask will not fade if you wipe it with your hands, because it is printed with a laser; the fake 3M mask will fade as soon as you wipe it. Seeing the fading, in order to save costs, the printing technology used is also very poor.

6. Comparing the seams of masks

The edges of the authentic products are very well sewn, and there are no extra threads visible; the sewing technology of the imitations is relatively rough, and the seams are clearly visible. .

Finally, I would like to remind everyone that the price of dust masks is ridiculously low compared to the market price, so you should pay special attention to it. Be sure to pay attention to the purchasing channels of 3M masks. It is recommended that you go to 3M authorized dealers or designated channels, including e-commerce channels, to purchase 3M masks, so that you can get the highest degree of authenticity and quality assurance. It is recommended to purchase 3M products through 3M authorized dealers in various places.
