Free Face Mask Pattern: Filter Pocket and Fitted Nose- 3d mask with filter pocket and nose wire pattern ,Many of the patterns I tried didn't have a pocket for a disposable filter or a pocket for a removable wire nose bridge to make it fit close to the face. This mask pattern includes: Removable wire nose bridge. Optional pocket to slip in a disposable filter (for superior filtration of particles) Items needed:Contour Face Mask with Nose Bridge Wire and Filter Pocket ...This mask uses the same basic pattern shape as my regular Contour Face Mask, but has additional features. The updated pattern, with pockets, is linked below. Adding nose bridge wire will let less air escape from the top of the mask and will force more air through the filter. I have heard it also helps minimize the fog you get if you wear glasses.
