Cambridge Masks filtration system, incorporating particulate filtering layers and military grade carbon meets N99 standard of particulate filtration, providing nearly 100% protection from particulate pollution such as PM2.5 and PM0.3.
Cambridge Masks are respirators that use military grade filtration technology to filter out nearly 100% of particulate pollution, gases, as well as bacteria and viruses in a fashion friendly mask suitable for the whole family. Cambridge Masks inner filtration layer is made from a 100% pure activated carbon cloth, which was originally invented by the UK Ministry of Defence. It was extensively developed and has been made into products for use in chemical, biological and nuclear warfare protection. We call this the British Pollution Solution.
