Q. How should you wear a 3M mask?

Answer

To wear a mask correctly, you should first pre-stretch the straps before placing the respirator on the face and position the respirator over the nose and mouth. Then, pull the top strap over the head, position it at the top back of the head and above the ears. Next, pull the bottom strap over the head and position it around the neck below the ears. Then, press the nose piece and mold it to the shape of the nose to seal air off effectively.
