What does a respirator provide?

  1. Repairs to the respiratory system

  2. Artificial respiration

  3. Measurement of breathing rates

  4. Filters for inhaled air

The correct answer is: Artificial respiration

A respirator is a device designed to protect the user from inhaling harmful airborne particles, gases, or vapors, primarily through the use of filters and valves. It is not responsible for providing repairs to the respiratory system, offering artificial respiration, or measuring breathing rates. The primary function of a respirator is to filter inhaled air, ensuring that the person wearing it can breathe safely in environments where the air may be contaminated. This is why the option that states a respirator provides filters for inhaled air is the most accurate choice. It emphasizes the protective role of the respirator in maintaining respiratory health by ensuring clean air is inhaled, thus preventing exposure to pollutants and infectious agents.
