3M 9551V KN95 Valved Particulate Respirator Masks

Earloop style with exhalation valve.
Highly efficient electrostatic filter cotton, providing a breathing resistance of less than 5% and a filtration efficiency of over 95% for non-oily particles.
Equipped with a sponge nose pad for a more comfortable fit.
Foldable design for easy portability and mask storage to maintain cleanliness.
Suitable for protection against dust and non-oil-based mists, as well as welding fumes, lead fumes, casting fumes, metal fumes, silica dust, and certain heavy metal particles.
Filtration efficiency for non-oily particles is at least 95%. It also reduces odorous levels of organic vapor (concentrations below the occupational exposure limit).
