Medical masks have always been a must-have for protecting the cold, especially in the smoggy winter, which is valued by the public.
Recently, the person in charge of the relevant state departments said that it is expected that the draft of the "Technical Specifications for Daily Protective Masks" will be announced before the end of the year. In the opinion draft, the raw material requirements, structural requirements, labeling requirements, and appearance requirements of the masks are all involved. The main indicators include functional index particulate matter filtration efficiency, expiratory inspiratory resistance index, and adhesion index.
Before the publication of the "Specifications" opinion draft, there are currently a variety of masks on the market, including disposable, gauze, cotton, and activated carbon. Of course, because of the different effects, the price is also different, the cheap one has a few cents, and the expensive one has tens of dollars. However, some masks are not without logos, labels, or even packaging.
The doctor reminded that it is necessary to pay attention to the cleanliness of the hands before wearing the mask, and it is not easy to wear for a long time, otherwise the nasal mucosa will become vulnerable and more susceptible to diseases. In addition, the choice of masks can not only look at the appearance, but also to see if it is clean and tidy, and combined with their actual needs to buy.
