Living Mask for Old

The life span of medical surgical masks is 4-8 hours. Old people usually forget to change their masks because of the memory decline. But the sense of smell doesn't fade easily. When the exhaled steam gradually wets out the viscose cloth which contains the citric, sour taste would be smelled,and the old would know it's time to replace the mask. Every breath lead to the result and if one use the mask very seldom the mask won't change the smell very soon. It shows the quality guarantee period of the mask and people won't abandon it because of forgetting and finally reduce the waste.
