Valve respirator

## respirator with valve
Respirator is an indispensable assistant in conditions of increased dusting or air pollution. It protects our lungs from harmful particles, but the comfort of using is also an important factor. It is here that a respirator with a valve of exhalation enters the stage. Let's figure out what it is and why it is needed.
### Why do you need a exhaust valve?
The main advantage of the valve respirator is the comfort of breathing. Imagine that you work in a dusty room and breathe all day through dense material. This can become quite tedious, cause discomfort and even headache. The exhalation valve solves this problem. It provides free exit of exhaled air, preventing the accumulation of moisture and heat inside the mask. As a result, you breathe easier and feel much more comfortable, which is especially important in prolonged work.
### How does the valve work?
The mechanism of the valve is quite simple. It is a small membrane that opens only when exhaling. When inhalation, the valve is closed, providing reliable protection against dust and other harmful particles. And when you exhale, the membrane opens, allowing exhausted air to go outside freely. Does this create an effect? ​​Breathing? Masks, significantly improving use comfort. It is important to note that modern valves are quite reliable and sealed, so they do not let air inward when inhale.
### when is it better to use a valve respirator?
A valve respirator is an excellent choice for working in conditions of increased dusting, where long -term wearing personal protective equipment is required. This can be work at a construction site, in a mine, wood processing, or any other activities related to dust or harmful aerosols. However, remember that the valve respirator does not protect others from exhausted particles, therefore, in conditions where protection is also required, it is better to use a respirator without a valve. The choice of the type of respirator always depends on specific working conditions and safety requirements.
