Ducted Fume Hoods

Ductless Fume Hood vs Ducted Fume Hood

Ducted fume hoods require ductwork to channel contaminants out of the lab using a fan mounted outside the building. These employ multiple pre-filters, HEPA filters, activated carbon filtration, and a strong fan. They're appropriate when there's a potential for being exposed to high volumes of particulate and toxic fumes. Ducted systems provide a minimal risk of dangerous fumes being recirculated back into the work environment. They are beneficial when the systems are used consistently or when highly toxic substances are in use.

Ductless fume hoods capture and remove contaminants and send clean, filtered air back into the lab without the need for external venting. They require HEPA and charcoal filters. Filter maintenance is more involved when using a ductless system. Filters may need to be changed anywhere from six months to annually.
