Brand New

If you has doubt about the five layers or thickness:We sure that our masks have five layers, one layer of black and four layers of white. As shown in the image: The black layer is non woven fabric, and the white layers have one Hot-air cotton, double Melt blown cloth and one Skin- Friendly Non-Woven fabric. We have professional test reports (No:210380066) from GTTC, and the GTTC meets the qualification requirements of ISO17025. Boncare masks are fully automated, and each layer is a special corresponding process. It is impossible to reduce one layer or weight by human intervention.If you has doubt about the smell:We sure that our masks don't contain any harmful substances, and we have the corresponding test report (No:WTZ21F08083566X1C). The test results are qualified, which proves that our KN95 mask is safe for wearing.The smells come from non-woven fabric itself, which is the normal smell of the raw material. The most important: The smell of this material is safe for human being if inhaled. If you are sensitive to the smell, we suggest you open the packaging and place it outside for 3-5 days before using it. We recommend that you wear mask for no longer than 4 hours. We recommend that you replace your mask with a new one every day. We recommend that you clean your face from sweat before wearing a mask. The ear- Loop meets KN95 Ear Loop Test Method "GB 2626-2019 6.11", which is: each ear loop, buckle and other adjustment parts of the mask should not slip or break under 10N tension, and last at least 10 seconds. Attention: If you use more power to stretch the ear loop, it may break, so please avoid stretching the ear loops vigorously. The length of the ear-loop is based on the American standard height, and there will be gaps between KN95 mask edges when the ear- loop length is greater than 20cm, which causes the KN95 mask can’t fit tightly. So our current length is the most suitable length for most of the customers. Attention: If you need masks which ear-loop length should be greater than 20cm, or your height is more than 180 cm, we recommend you purchase larger size masks from other sellers. We hope you purchase the most suitable products to achieve the most effective protection. Qualified Manufacturer: GUANGDONG ZHIZHEN BIOLOGICAL MEDICINE CO, LTD.
