Proper use of face masks is essential to maximize their protective benefits. First, wash your hands with soap and water or clean them with a disinfectant. Then, place the mask on your face so that it covers your nose, mouth, and chin completely, ensuring there are no gaps between the mask and your face. Avoid touching the mask while wearing it, and if you need to adjust it, sanitize your hands again. Disposable masks should be discarded after each use, and cloth masks should be washed regularly.
