PAPRs are reusable respirators that can be used to protect against gases, vapors, or particles, when equipped with the appropriate filter, cartridge, or canister. They are battery-powered with a blower that pulls air through attached filters or cartridges to clean it before delivering it to your breathing zone. PAPRs provide low breathing resistance with a high level of protection.

PAPRs often have a hood or helmet that covers your nose, mouth, and eyes. Therefore, they also provide eye protection. A PAPR may have a tight-fitting half or full facepiece or a loose-fitting facepiece, hood, or helmet.

Unlike tight-fitting PAPRs, loose-fitting PAPRs do not require fit testing. They may be a good alternative if you have facial hair or are unable to pass a fit test with a tight-fitting respirator.
