The 3M 7500 series reusable masks give you a flexible system for gas, vapour and particulate protection to suit a variety of applications. With user comfort in mind, the 7500 face masks feature a well-balanced head harness that distributes weight evenly while avoiding sensitive areas on your head – helping to minimise fatigue. 

Experience improved breathing in hot and humid conditions, with the Cool Flow valve which reduces exhalation resistance and results in a downward flow of exhaled air. This means less heat build-up and reduced fogging when used with eye protection.

The 7503 respirator utilises a twin filter system, which means a more even weight distribution and easy connection with a range of filters. The dual filter design also allows for lower breathing resistance and increased comfort for prolonged use.

The low-profile respirator minimises disruptions to your field of view and provides a more comfortable streamlined fit. The 7500 respirator can be easily used while welding using the 3M™ Speedglas™ 9100 series welding helmets.

The 3M reusable respirators are suitable for industries including welding, construction, fibreglass, agriculture, building, automotive and garden maintenance. Filters are available for protection against contaminants including organic vapours, nuisance level acid gases, hydrogen fluoride, acid gas, ammonia and methylamine, and organic vapours and formaldehyde.
