Fume hoods protect against chemical fumes and vapors, while biosafety cabinets protect against pathogens and biological agents. Biosafety cabinets are another category of laboratory equipment that is frequently confused with fume hoods. Both use airflow to protect, but the focus of protection is on different hazards.
A biosafety cabinet (also called a biological safety cabinet or BSC) uses HEPA filters to remove infectious organisms from exhaust air. Depending on the class and type, a biosafety cabinet may also use HEPA filters on intake air to protect the product from contamination. By contrast, a fume hood does not usually use HEPA filtering on exhaust air vented outdoors.

A ducted fume hood relies on the facility's ventilation system for venting exhaust air outdoors using ducts. The fan or blower is typically located on the roof of the building, allowing for quiet operation of the fume hood. To prevent recirculation of contaminated air, the ductwork for a fume hood should be separated from the rest of the facility's ventilation ducts.
A ductless fume hood, also called a recirculating fume hood, uses a blower on the fume hood to pull contaminated air through a HEPA filter, and then recirculates the air back into the room. The type of filter required varies depending on the chemistry, so the operator must ensure use of the proper filter for safety. Filters also must be changed regularly for safety.
A fume hood is a ventilated enclosure used to control exposure to hazardous or odorous chemicals. An exhaust fan draws air into the front opening of the hood, then up and out of the hood through the ductwork. Because the air that is pulled into the hood is not filtered, fume hoods only offer protection to its users and no protection to the products inside the hood.
Hood performance and efficiency depends on an adequate and uniform velocity of air moving through the sash opening. Hood performance is adversely affected by many factors including mechanical malfunction, drafts or open doors and windows, and poor operating procedures of the person using the hood.
