A notable occupational use of dust masks is in farming, where dust masks are used to avoid the effects of farmer's lung, a disease caused by the inhalation of dusts from agricultural products. [1] The toxicity mainly comes from allergy to mold in the dust, which can lead to lung damage due to the immune response, [ 7 ] as opposed to an inherent ...
All parts of the PAPR are visible: the waist unit holding the fan, filter, and battery; the hose; and the mask, in this case a flexible, loose-fitting one. A powered air-purifying respirator (PAPR) is a type of respirator used to safeguard workers against contaminated air.

Respirators filter the air to remove harmful particles and alongside the breathing ...
These respirators are sometimes known as dust masks for their almost exclusive approval only against dust nuisances: In Europe, regulation allows for dust masks under FFP1, where 20% inward leakage is allowed, with a minimum filtration efficiency of 80%. [127] South Korea allows 20% filter leakage under KF80.
There are two main types of respirators. One type of respirator functions by filtering out chemicals and gases, or airborne particles, from the air breathed by the user. [5] The filtration may be either passive or active (powered). Gas masks and particulate respirators (like N95 masks) [6] are examples of this type of respirator. A second type ...
