3M 7744 Dust Filter Sheet protects against dust, smoke, and metal fumes. P2 filtration standard.

Particulate filter 3M Protects against dust, smoke, and metal fumes; P2 filtration standard
A filter sheet without a direct activated carbon layer (unlike model 7744C), but still offers high particle filtration efficiency. Certified to European P2 standard, meaning it can filter at least 94% of particles generated from mechanical and thermal processes, such as dust, mists, and metal fumes. This filter sheet is made from electrostatically charged polypropylene to enhance the efficiency of trapping fine particles, and also helps protect against nuisance-level acid gas chemicals (levels that do not harm health but cause irritation). With its ultra-thin and lightweight design, it adds no burden to the user and is easy to use with 3M™ 7770K Series half-face respirators (7771K, 7772K, 7773K).
