is not only one of the best anti-air pollution masks, it also filters out nearly 100% of bacteria and viruses. Because the mask filter of Cambridge Mask
is sprayed with a layer of silver during the production process, it can kill almost 100% of viruses and bacteria. The Cambridge Mask
mask successfully passed the test and is currently the only mask on the market that can be used multiple times and can effectively prevent air pollution and filter viruses and bacteria. This is the British solution to air pollution. The filtration system of Cambridge Mask
combines a particulate pollution filter and a military-grade activated carbon filter, which meets N99 level filtration standards and filters nearly 100% of particulate pollutants for the wearer, including PM2.5 and PM0.3.

The masks are available in three models and can be worn by adults and children. They can protect you and your family from air pollution, bacteria and viruses.

Frequently asked questions about anti-smog mask : 1. How long can the anti-smog mask be used? The designed service life of our masks is 200 hours. If used for 2 hours a day, the masks can last for 3 months. 2. How to choose the size of the anti-smog mask? Please choose the size according to your weight and face shape. The appropriate size can strengthen the sealing of the mask, giving you a more comfortable wearing experience and better filtration effect. 3. Can anti-smog masks be washed? How to clean? The mask can be hand washed, but be careful not to add detergent when cleaning. It is recommended to clean the mask every 14 days of wearing it. Excessively frequent cleaning or machine washing may cause irreparable damage to the mask. 4. Does the anti-smog mask have a filter element? Does it need to be replaced? Our masks do not need to replace the filter element. The mask itself is composed of 3 layers of different filter materials. This design can give you better filtration effect and longer use time------------- -------------------- My experience of using this mask: New masks will have the smell of activated carbon and filter elements, which are harmless to the human body. My experience is that after wearing it, the airtightness will be better, my eyes will not breathe out in winter, and my ears will not feel soft and unable to hang on. Even if it can be washed, it is still recommended that you buy two replacements. Masks are consumables after all, and it is impossible to buy one to last a lifetime~
