• Almost 100% of gas based air pollution, including odours such as Volatile Organic Compounds (VOCs), Ozone, Benzathine, and Formaldehyde. These particulates you can find in petrol fumes, chemical emissions and from many industrial processes.

Has the mask been independently tested?
The filters used in the Cambridge Mask meet the N99 standard (higher than N95). This is a US Government specification for pollution masks. Cambridge Masks have been independently tested by Nelson Labs, USA which confirmed almost 100% of particulate pollution, bacteria and viruses were successfully filtered when tested. We have also tested to meet the standards for Chinese NK-95 and Korean Food and Drug Administration requirements. The masks use a triple-layer filter system which will protect from a range of airborne contaminants.
• 99.6% average filtration of viruses
• 99.77% average filtration of bacteria
• 99.7% average particulate filtration down to 0.3 microns
