What is the main purpose of a respirator?

Explanation:
The essential function of a respirator is to keep air contaminants out of your respiratory system by filtering or purifying the air you breathe. It protects your lungs from inhaling dust, fumes, gases, or vapors. It doesn’t humidify air, and it doesn’t provide extra oxygen as its main purpose (unless you’re in a special oxygen-deficient situation where a different type of system is used).
