What you need to know about masks.

The issue of wearing masks has become particularly relevant for Canadians due to coronavirus. ARPShop.ca tells what types of masks are especially effective, and how to use them correctly.
Gauze masks were popular a few years ago. Such masks helped against a bacterial infection, but not a viral one, since the viruses are too small in size and easily penetrate this barrier.
Non woven masks
Non-woven masks have a finer structure, which allows you to retain bacteria of a fairly small size. These masks use special polymer fibers. These masks can be from two to four layers, they have rubber ear loops and a nasal retainer.
These masks have four layers and are used in surgery. In their design, there are two outer layers and a protective anti-liquid layer, which is necessary to protect the face from the ingress of biological fluids.
Carbon masks consist of a special filter layer that retains even micro-particles. This mask is ideal for protection against dust and chemicals.
Respiratory mask is most often used to protect the respiratory tract in the workplace. Respirators can be filter or air. The first type is equipped with a special filter that cleans the incoming air from impurities. Such a mask consists of three layers of protection. External protects against biological fluids, the middle protects the filter, and the internal protects against moisture. The second type is more complex, high-quality and expensive: such models are equipped with a special cylinder or cartridge, which, due to the chemical reaction, supplies air to the worker.
Children's masks can be both non-woven and gauze. They are intended for children from three to 14 years old. The only difference from the rest is that most often images that cause interest in a child are applied to the mask. Also, a special anatomical shape makes it optimally suitable for a child's face.
Rules for using masks
The rules for wearing masks are the same for all types.
The material should fit snugly to the face, without gaps.
Masks need to be changed every 2-4 hours. But if the mask is wet from coughing, sneezing or breathing, it should be replaced immediately.
It is impossible to restore the protective properties of a disposable medical mask; therefore, the mask cannot be reused.
Do not move the mask to the chin or put it in your pocket, and then use it again.
Touching the mask with your hands while wearing is not recommended.
It is customary to wear medical masks with white side to face, and colored masks - outward. The nasal retainer is usually sutured from the inside.
If the manufacturer provides the mask with additional properties, for example, with an external water-repellent layer and an absorbent inner one, this is indicated on the package.
