Choose the right respirator according to the potential harmful substances

In the field below, enter the name of any harmful substances that will be handled or a substance numeric identifier (such as the CAS registry number), then choose from the suggested models.

Once you have selected the relevant substances, respirators of the right protection class that meet your requirements will be displayed. For some hazardous substances two protection classes might be appropriate, in which case a model of the higher protection level is recommended.

Please note that the appropriate respirator should not be chosen solely on the basis of the harmful substance, but also reflect substance concentration and other factors. Further information can be found under choice of respirator.
