Which statement about respirators is true?

Explanation:
Respirators protect by delivering clean air or filtering contaminants, not by creating oxygen. Their job is to provide breathe-able air from the surrounding environment or from a supplied air source, while removing particles or harmful substances. Because of that, they do not generate oxygen. They also don’t purify water, and they don’t emit carbon dioxide—they simply channel the air you breathe; any CO2 comes from your own respiration, not from the respirator itself.
