There are many types of categories because of their different uses. How to choose the type you need is to understand its product characteristics. Choosing the wrong product is equivalent to being useless. How to use foldable disposable masks Let’s learn the basics of masks together.
How to choose a mask scientifically?
Experts said that in addition to providing effective protection, wearing a mask must also take into account the comfort of the wearer, and must not bring negative effects such as biological hazards. Generally speaking, the higher the protective performance of the mask, the greater the impact on the comfort performance. When people wear a mask and inhale, the mask has a certain resistance to air flow. When the inspiratory resistance is too large, some people may feel dizziness, chest tightness and other discomforts. Different people have different industries and different physiques, so the requirements for the tightness, protection, comfort, adaptability and other indicators of masks are also different. For some special groups, such as children, the elderly, and people with respiratory and cardiovascular diseases, it is necessary to carefully select the type of mask. On the premise of ensuring safety protection, avoid accidents such as hypoxia and dizziness when worn for a long time.
How to wear a mask correctly?
Taking ordinary medical masks as an example, in order to facilitate wearing, ordinary medical masks generally use elastic ear straps to fit. There are two sides of the mask, there are several layers of wrinkles on the surface, and there is a hard strip on the side. When wearing it, the side with the hard strip should be on top first, because the hard strip can be used to pinch the bridge of the nose tightly to ensure the airtightness of the mask. Then the folds of the mask must be downward, because if the folds are upward, bacteria, viruses or dust will easily stay in the folds.
How often should masks be changed?
Due to the different types of masks, different users, and different use environments, it is not possible to uniformly stipulate how long masks are used. Under normal circumstances, it is recommended to replace disposable medical surgical masks at least every 4 hours; if the mask is wet or dirty with secretions, or is damaged, or feels increased breathing resistance, it should be replaced immediately.
