There are two types of respirators air purifying and supplied air. The air purifying respirator removes contaminants by passing ambulant air through the air purifying element while atmosphere supplying respirators provides fresh air from an uncontaminated external source. Air purifying respirators come in three basic types articulate removing, vapor and gas removing or a combination of the two as you breath in air purifying respirators have replaceable filters or air purifying elements to remove solid or liquid hazards from the air. Some contaminants are remove from the air by a canister or cartridge with a filter, solvent, catalyst or combination of these. Two common types of supplied air respirators are the self contained breathing apparatus (SCBA) and the supplied air respirator in which the air is sent from an outside source through a hose or air line to your mask or hood.
