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.

• 99.77% average filtration of bacteria
• 99.7% average particulate filtration down to 0.3 microns
