How Do Air Purifying Respirators Work?

APRs function by using filters or cartridges to remove contaminants from the air. They rely on the wearer to breathe in air through these filters, which trap or neutralize harmful substances. There are different types of APRs, including particulate respirators and chemical cartridge respirators, each tailored for specific types of contaminants. The selection of the appropriate respirator depends on the nature and concentration of the toxic agents present in the environment.
