Can Workers Reuse Disposable Respirators?

Usually, disposable respirators are designed for single use or limited use, depending on the type of respirator, workplace conditions, and the manufacturer's instructions.

A worker should not automatically reuse a disposable respirator just because it still looks clean. During use, the respirator can become contaminated, damaged, or less effective.

Before considering reuse, check:

• Manufacturer's instructions for reuse and storage.
• Whether the respirator is damaged, dirty, wet, or difficult to breathe through.
• Whether it has been exposed to hazardous substances or contaminants.
• Whether the workplace has specific procedures for storing and reusing respirators.

For example, a disposable filtering facepiece respirator such as an N95 should be replaced when it becomes damaged, soiled, contaminated, or difficult to breathe through.

So, the safest approach is simple: follow the manufacturer's instructions and workplace respiratory protection procedures rather than assuming a disposable respirator can be reused.
