Disposable respirators offer protection against particulate hazards and have a number of benefits: they are hygienic, easy to use and require little to no maintenance. In addition to this, some 3M R rated respirators can be used for more than one shift if they are in a reusable condition and are cleaned after use.

As there are many different disposable respirators with various protection levels and styles to choose from, it is important to select the mask with the correct level of protection for your application.
