How to use disposable medical sterile masks

The smog in many cities is very serious now, so many people wear masks when they go out. There are many kinds of masks. Generally, disposable medical sterile masks are very convenient. They are simple and can prevent bacteria. So how do you wear this kind of mask? First of all, you need to check which side of the mask is the front and which is the back. Don't wear it upside down. Generally, the white side is worn inside, and the colored side is worn outside, and there is usually a metal strip on the outside.

The correct way to use disposable masks:

1. The mask has two sides, white and blue. Turn the white side inwards and the side with the metal strip upwards. First, tie the two lower straps behind your neck and tighten them! Make sure the bottom edge of the mask reaches the base of your chin.

2. Pull up the upper edge of the mask to cover your mouth and nose. Pull the two upper straps behind the ears and tie them tightly on the head. Do not tie them on the ears.

3. Use the index fingers of both hands to press the metal wire at the root of the nose on the upper side of the mask to make it close to the skin of the nose, then gradually move the index fingers to both sides to make the entire mask close to the facial skin.

Disposable medical sterile masks have straps on the edges, which are directly put on the ears, so when wearing the mask, you can put it on directly after confirming the front and back. The key step here is the metal strip on the mask. You need to press the metal strip on both sides of the nose with your hands. It is considered to be worn only after it is pressed tightly.
