Four Types Of Breathing Half Masks
Half mask refers to a kind of mask mainly covering the nose and mouth while those covering the whole face, including the eyes, are called full-face respirators. Half mask especially surgical mask or medical mask becomes popular since Covid-19 exploded in recent years. Half mask includes medical mask, cotton mask, bamboo charcoal mask and 3M mask and so on. Let’s take a look at these four types of masks together.
Surgical mask consists of a piece of cloth processed by special procedure and two belts. The cloth can be divided into inner, middle and outer layers. The inner layer is made of skin-friendly material. The middle layer is an isolation filter layer and the outer layer is a special material antibacterial layer. This mask performs well in hydrophobicity and air permeability, and has remarkable filtering effect on tiny virus aerosol or harmful dust. However it cannot effectively filter PM10 and PM2.5. So if you are living in a city with serious air pollution problem you had better not choose common surgical mask.
In short, blue masks are mainly used for preventing bacteria and viruses. That is to say, doctors and nurses should wear cotton masks or 3M when they leave the hospital. They were mainly used in hospitals but with the explosion of Covid-19, blue masks or surgical masks are widely used especially taking a transport such as bus or subway.
As its name implies, cotton mask refers to a kind of mask solely made by a piece of cotton cloth. It is also easy to made by yourself. It also allows you to wash and reuse repeatedly since this fabric has a good breathability. But it has a low protecting level(it also depend the layers and quality of the fabric).
It would be the best choice for the elderly and children who have to stay in outdoor for a long time since their cardiopulmonary function is not complete. Therefore they cannot wear masks with poor air permeability for a long time. (Of course, they can't wear too thick cotton mask for a long time).

Bamboo charcoal mask
Bamboo charcoal fiber is made by bamboo with new technology. That makes the natural micro-pores of bamboo finer and honeycomb.This bamboo mask performs well in moisture absorption, air permeability, and anti-bacterial. What’s more, it also is an eco-friendly product which can keep warm in winter.
In fact, charcoal and bamboo charcoal are mainly used to filter water. In addition they can be used to absorb the water in the air. Therefore it performs not very well in filtering PM2.5. Theoretically speaking, bamboo charcoal fiber masks with the same thickness are not as protective as ordinary cotton masks.
3M masks means all mask products manufactured by 3M including thermal masks, particulate respirators (dust masks), medical protective masks, and surgical masks and so on. It is also a widely used mask all over the world since it is cheaper than most of cotton mask and at the same time boasts a low filtering rate of bacteria and virus. However, washing are banned but it can be reused for two or three times. The shortage of this mask is low breathability so it is hard to wear it for a long time.
We have introduced four common half masks sold on the market. The former three are made by different materials and processing way while the last one is the most common mask brand with all functional masks. If you have picked some basic knowledge of masks’ materials and function, some shopping traps you can easily bypass.
