Do you know how dirty the mask you wear is? Wearing a mask is a must when cleaning or on the field due to numerous invisible germs and dust. However, we cannot check with the naked eye how long we have used the mask or until when we should use it. With this color-changing mask, the user can check how much the mask has been contaminated by dust and bacteria. It consists of dual covers. You peal away the first cover like a banana peal if it has discolored after using it for some time. You use the mask with the second cover after throwing out the used first cover.
