Abstract
An emergency smoke filter for use by firefighters and the like has two stages: the first stage is a paper filter and the second stage is a charcoal filter. The emergency smoke filter is intended for use only in the event that a firefighters primary source of breathing clean air (a self-contained breathing apparatus or SCBA) malfunctions or runs out of air in a toxic, smoke filled environment. The emergency smoke filter does not replace an SCBA but augments it in case the SCBA is not working. The emergency smoke filter attaches to the firefighters SCBA in the slot for the regulator once the regulator is removed. The emergency smoke filter is intended for only one use and it can be deposed of thereafter.
