"Wear a mask and go out, don't step on thunder!"
During the epidemic period, masks are a must-have for us when we go out. But did you know that not all masks are suitable for wearing on the go. In this article, I'm going to share four types of masks and tell you why they're not suitable for going out. Let's take a look!
Type 1: Expired masks
The story begins with an experience of my dad rummaging through a drawer. He found a box of masks and thought to himself, "This is a hot commodity, we need to keep it for backup." However, after he put on the mask, I couldn't help but remind: "Dad, this mask is expired!" He was stunned for a moment, and quickly checked it, and sure enough, it was expired. Looking at my father's helpless expression, I couldn't help but sigh.
The protective effect of expired masks may be greatly reduced or even completely ineffective. Because the mask material will gradually age over time, it will lose its original filtration efficiency. Therefore, it is important to pay attention to the production date and expiration date of the mask, and replace it with a new mask in time.
The second type: unqualified masks
Once, I saw someone on the Internet peddling masks, which were cheap and looked good quality. I thought to myself, "If only I could save some money", so I didn't hesitate to place an order. However, when I received the mask and looked closely at the label on the package, I was shocked – it turned out to be a substandard mask!
Unqualified masks may have various safety hazards, such as poor filtration effect and high breathing resistance. Going out with this mask is tantamount to exposing yourself to the risk of being naked. Therefore, when buying masks, you must choose formal channels to ensure that the masks meet the corresponding standards and certifications.
The third type: masks that do not fit
One day, my friend Xiao Ming suddenly asked me to borrow a mask, saying that he forgot to bring it when he went out. I pulled out some spare masks for him, but he picked them up and picked them up, and in the end he only got a medical mask. I asked him curiously why he didn't choose the other, but he smiled and said, "This is the best for me!"
I was a little puzzled and asked him why he had chosen this way. Xiao Ming explained that he had difficulty breathing, and the medical mask was breathable and most comfortable to wear. It dawned on me that the choice of masks varies from person to person and cannot be generalized.
A mask that does not fit can be inconvenient or even dangerous for the wearer, so when choosing a mask, choose the most appropriate type according to your situation.
Fourth: defective masks
I still remember one time, I bought a box of masks, which cost a lot of money, thinking that it should be of good quality. However, as soon as I unpacked it, I could smell a pungent chemical smell that made me frown.
After some investigation, I learned that this mask was made of defective materials. These defective masks may contain harmful substances, such as formaldehyde, benzene, etc., which may cause health hazards when worn for a long time.
The key to avoiding buying defective masks is to choose reputable brands and formal channels to buy masks. Remember, safety always comes first!
In times of pandemic, the choice of masks is crucial. We must not only ensure the quality of the masks, but also choose the right type of mask according to the individual situation. I hope this article can remind everyone to protect their health and safety, wear a mask when you go out, and don't step on thunder!
