Color change mask / mask

Color change mask

In our daily life, we wear a mask for a short time. If we wear it once and throw it away, it will cause waste. But if we wear the same mask for a long time, it will also cause physical discomfort and not play a protective role. My idea is to add a color changing device on the basis of the existing masks, so that users can know the duration of mask use by color changing instructions during the process of using masks and judge when they can discard them. When not in use, the mask is green and transits to orange. When the color changes to red, the mask can be discarded. Using a nano material, it can change colors according to the length of use.
