What is the difference between a respirator and a surgical mask?
Respirators are not the same as surgical masks. Surgical masks do not protect against breathing in very small particles such as dust or mold because they do not fit tightly to the face, allowing air particles to leak in around the edge of the mask. Other types of masks, such as dust masks, that appear similar to respirators may not be designed to protect the wearer from airborne hazards such as mold and should not be used for this purpose.
