What should not be expected from the use of air-purifying respirators?

The use of air-purifying respirators is designed to filter the air inhaled by the user, but they do not provide complete removal of all airborne contaminants. Instead, these respirators are intended to reduce the concentration of specific pollutants or particles in the air, thereby minimizing inhalation risks and improving overall safety in a work environment. They are effective in providing basic respiratory protection but are not capable of completely eliminating exposure to all harmful substances present in the air.

This understanding highlights the limitations inherent to air-purifying respirators and clarifies that while they play a significant role in enhancing safety and reducing health risks, they cannot guarantee the total removal of all airborne hazards, making the choice of full removal of contaminants an unrealistic expectation.
