Abstract
A mask includes a thin film layer having a plurality of net-shaped irregular pores to provide a ventilating effect, two loop-shaped straps mounted on two ends of the thin film layer, and two adjusting rings each movably mounted on a respective one of the straps. The thin film layer is made of soft and tough material, such as e-PTFE, TPE, TPEE, COC or FRP. Each of the pores has a size smaller than that of dust, water molecule, bacterium and virus to isolate and prevent the dust, water molecule, bacterium and virus from entering the thin film layer. When the loop-shaped straps are put on a user's ears, the adjusting rings are moved on the loop-shaped straps to adjust the size of each of the loop-shaped straps so as to fit the user's face.

A mask, comprising:
- a thin film layer having a surface formed with a plurality of net-shaped irregular pores to provide a ventilating effect;
- the thin film layer is made of soft and tough material;
- the thin film layer is made of e-PTFE (expanded polytetra-fluoro-ethylene), TPE (thermoplastic elastomer), TPEE (thermoplastic polyester/polyether elastomer), COC (cyclic olefin copolymer) or FRP (fiber reinforced plastic);
- each of the pores of the thin film layer has a size smaller than that of a dust, water molecule, bacterium and virus to isolate the dust, water molecule, bacterium and virus efficiently so as to prevent the dust, water molecule, bacterium and virus from entering the thin film layer.
