As you breathe through them, these respirators filter out contaminants in the air. Throw them out when breathing is difficult or if they’re damaged or dirty. They're best for short-term use and areas with low levels of contaminants.

N100 respirators filter out 99.97% of solid particles. They’re not oil resistant. To achieve the filter rating, you'll need a respirator that creates a tight seal with your face to prevent contaminants from entering through the sides. Choose the respirator that matches the style you have been fitted for. Respirators with an exhale valve reduce breathing resistance and hot air buildup.

Respirators with a mesh shell hold their shape in heat and humidity.

Respirators that cannot be sold outside of the United States or Canada are restricted due to product regulations.
