Like other tools, respirators need maintenance to work properly. The job your respirator does is important, so ensure that all the parts are there and working right.
Check the facepiece, filters, valves, straps and buckles.
Filters must be changed regularly. An immediate change is necessary when:
Damaged, missing or poorly seated valves can drastically reduce the protection provided by your respirator.
Check the inhalation valves.
Remove filters and make sure the flapper valve (usually a flexible disk) is not missing or damaged. Make sure that it’s seated properly in the valve assembly.
To inspect the exhalation valve, remove the cover at the bottom of the respirator. Check the valve for damage and proper seating.
Make sure that straps and buckles are free of damage and function properly.
Check for holes, cracks and splits.
