The BUFF® Filter Mask perfectly covers the user's nose, mouth and chin. When you put on and take off the mask you should do so with the utmost care, to avoid contaminating yourself.
How to put it on, step by step:
Before putting on the mask, wash your hands thoroughly with soap and water, or disinfect them with antiseptic gel.
Place the filter in the inner pocket of the mask with clean hands as instructed.
Place the mask on your face, making sure to cover your nose and mouth.
Place the top strap around your head and adjust the mask to fit your nose and ears.
Place it on your chin and fasten it to your neck with the lower strap.
Once in place, try not to touch the mask with your hands while wearing it. If you do, immediately wash your hands with soap and water, or use antiseptic gel.
