a negative pressure respirator brings fresh air to you through a hose. true false

The statement "A negative pressure respirator brings fresh air to you through a hose" is false. A negative pressure respirator works by the wearer inhaling and creating negative pressure inside the mask, which pulls air through a filter from the surrounding environment, not necessarily through a hose providing fresh air. Fresh air supply through a hose is generally associated with positive pressure respirators or supplied-air respirators, not negative pressure respirators. Negative pressure respirators rely on ambient air filtered through the mask, not on air supplied from an external source through a hose.
