Whetlerite carbons are Cu, Cr and Ag impregnated activated carbons used for respiratory protection against super toxic nerve, blister, blood and choking agents in the military. Whetlerite carbons are used in nuclear, biological and chemical (NBC) filters for collective protection, and in NBC canisters, as part of individual gas masks, for personal protection. Flexus Global exports impregnation of active carbon and whetlerite carbon to various countries.
