Laboratory fume hoods are exhaust hoods specifically designed to draw air away from the working area to protect laboratory operators from inhaling hazardous air contaminants such as carbon monoxide or other toxic chemicals. There are two main types of chemical fume hoods. Ductless laboratory vent hoods filter air through activated charcoal and HEPA filters and release cleaned exhaust in the laboratory room. These hoods usually have greater portability and higher CFM capacity than the ducted lab hoods. Ducted lab ventilation hoods draw fumes inside the building’s exhaust system where they are treated and then released outside.

Fume hoods are a form of regulation in environments that are exposed to harmful vapors and fumes. In order to protect people from the harmful effects of these fumes, fume hoods are used to get rid of the harmful aspects and allow the individuals to work safely. Labs use fume hoods when working with substances that let off a harmful fume or odor. Laboratory workers can work with substances directly under the fume hood, or simply place the substance in the fume hood after the work is done.
