A minimalist face mask that relies on simplicity. Equipped with just a flexible rubber strap, securing this device is effortless. The small opening measures roughly 1 millimeter in diameter and can be precisely created using a PCB drill machine's precision capabilities. A polypropylene non-woven fabric serves as the essential filter component to be inserted inside, successfully blocking unwanted particles from entering the air stream with its effective barrier properties.
