Guard Against The Secondary Pollution Of Disposable Masks

In the face of a wide variety of masks, many people prefer disposable masks, and many experts also advocate the use of disposable masks. In fact, disposable masks are not better than traditional masks, and even do more harm than good.

 

First of all, ordinary disposable masks have poor air permeability, which can cause secondary pollution. Common disposable masks are mostly made of melt blown fabric / non-woven fabric, and the main raw material is polypropylene. Although the mask has only a few thin layers, its air permeability is poor. It not only hinders the entry of fresh air, resulting in hypoxia, and the decline of the resistance of nasal mucosa, but also makes the exhaled air unable to pass through the mask smoothly, causing repeated inhalation of dirty gas, leading to respiratory tract infection.

 

Second, ordinary disposable masks have poor water permeability. If you wear them for a long time, they will be filled with water vapor. In this humid and warm environment, it is conducive to the bacteria to reproduce on the mask. Such masks not only can not block pathogenic bacteria, but will "send bacteria into the mouth", causing respiratory tract infection.

 

Third, ordinary disposable masks may not guarantee sterility in the production process. Recently, the media have exposed the inferior masks produced by the black workshop. These masks have already been contaminated by bacteria. Can you prevent diseases by wearing them on your mouth?

 

In addition, the masks made of these chemical fiber meltblown / non-woven fabrics may also contain certain chemical elements to stimulate the bronchus. For some patients with allergic rhinitis, they are an allergen, which can easily stimulate the nasal cavity and aggravate the allergy.

 

Fourth, ordinary disposable masks have a short service life and are often discarded in a day or less. Most of the discarded masks contain respiratory secretions and sputum of patients, which contain a large number of bacteria or viruses. The masks that are not treated as medical waste and not disinfected are discarded in the environment, which is more likely to cause the spread of diseases. Moreover, this disposable mask is not easy to degrade, but also easy to cause environmental pollution.

 

Therefore, the best mask to wear ordinary gauze mask. Gauze mask has the characteristics of good air permeability, strong water absorption, easy to keep dry and clean. It is soft and comfortable to wear on the mouth and nose, and can protect the mouth and nose and filter bacteria.

 

In addition, the gauze mask can be used repeatedly, and it can be put away after cleaning. It is not easy to cause disease transmission and environmental pollution.

 

However, gauze masks should be replaced and cleaned every day to keep them clean.
