BK Filters provide an added layer of protection to any BK mask. Simply slide the filter into the attached sleeve on the backside of the mask. The removable MERV 16-rated filter protects against 90% of particulates 0.3 microns or larger. In addition, our filter material is 42% more efficient and allows up to 84% more air flow than products currently on the market for protective masks. Available in individual, 5-pack or 10-pack quantities.
