What does a PAPR do with contaminants?

A Powered Air-Purifying Respirator (PAPR) is designed specifically to protect the wearer by providing a continuous flow of purified air. The distinguishing feature of a PAPR is its integrated battery-powered blower, which actively pulls contaminated air through a series of filters or cartridges. This process efficiently removes harmful particles, gases, and vapors from the air before it reaches the user.

The effectiveness of a PAPR in hazardous environments lies in its ability to create a positive pressure inside the respirator. This feature not only ensures that clean air is delivered but also minimizes the chance of contaminated air leaking into the breathing zone of the user. Thus, the correct option highlights the fundamental function of a PAPR, which is to remove contaminants from the air using its blower mechanism, ensuring the user has access to cleaner, breathable air while engaged in potentially harmful tasks.
