thingiverse

Respirator with interchangeable filter POC. This prototype is strictly for demonstration purposes and not intended for actual use. The removable filter was secured to the inner layer of the respirator using hot glue. Subsequently, the outer cover was adhered to the mask using a similar technique. Weatherstripping, commonly used for sealing windows and doors to prevent drafts, was applied around the edges of the mask to ensure a snug fit against the face. An elastic hair tie was modified by cutting and sewing through each side loop. Measurement guidelines are based on distance from the center of the nose bridge to the chin bottom. XS = 85mm, S = 95mm, M = 105mm, L = 115mm, XL = 125mm.
