This face mask made from waste plastic bottle can be washed, cleansed with antiseptic e.g. Detto solution, reused as many times as you want. The filter covering the screw cap hole is to be changed. The filter patches can be generated from one normal disposable face mask or using other materials such as tissue paper, cotton wool etc. The coffee filter is added for extra filtration of air. Of course, it should be changed accordingly.
