A fume hood is typically a large piece of equipment enclosing five sides of a work area, the bottom of which is most commonly located at a standing work height.
These units generally have a fan mounted on the top (soffit) of the hood, or beneath the worktop. Air is sucked through the front opening of the hood and through a filter, before passing through the fan and being fed back into the workplace. With a ductless fume hood it is essential that the filter medium be able to remove the particular hazardous or noxious material being used. As different filters are required for different materials, recirculating fume hoods should only be used when the hazard is well known and does not change. Ductless Hoods with the fan mounted below the work surface are not recommended as the majority of vapours rise and therefore the fan will have to work a lot harder (which may result in an increase in noise) to pull them downwards. Units with the fan mounted above the work surface have been proven to offer greater levels of safety.
A benefit of ductless fume hoods is that they are mobile, easy to install since they require no ductwork, and can be plugged into a 120 volt or 240 volt outlet.
