Make your own face masks using two sheets of kitchen roll
Since there seems to be a shortage of face masks, which should be disposed of every 4 hours, try making your own by folding a thickness of t2o sheets of kitchen roll in about 2 cm folds, first one way then the other. One folding complete, make a fold either end, insert a rubber band, and staple the fold to keep them in place. Place the rubber bands over ears, and separate the folds to cover the maximum of your face. Of course, make the masks using clean hands and surfaces.
