Ductless fume hoods, or filtered fume hoods, are self-contained, filtered enclosures that remove hazardous fumes, vapors and particulates from the immediate environment. Typically used in locations where outside ventilation cannot suffice, a ductless fume hood is a necessity to eliminate high percentages of harmful contaminants to protect users, applications and the atmosphere.
There a few key characteristics that distinguish Ductless Fume Hoods from Conventional Ducted Fume Hoods (that typically vent outdoors):

Environmentally-Friendly: In many cases, ducted exhaust hoods empty extracted fume and particulate directly outdoors without sending it through a filtration system first. Ductless Fume Hoods trap hazardous particulate in filters so they can be disposed of properly.
Energy Efficiency/Cost Efficiency: Ductless Fume Hoods recirculate existing room air, while externally ducting systems remove heated, cooled, or dehumidified air outdoors, which requires that air to be replaced. This has the potential to waste energy and increase cost.
Minimal Maintenance & Installation Requirements/Easy Mobility: While externally ducting exhaust hoods require complicated installation because of ducting construction, Ductless Fume Hoods can be up and running with minimal installation. They are essentially “plug and play” solutions. Ductless Containment Hoods do not require any ducting or external venting and can be moved from location to location with relative ease. The only maintenance requirements are replacing saturated filters and wiping the hood down with appropriate cleaning supplies from time to time.
All specifications are nominal and subject to change without notice. Not intended for explosive or highly flammable applications. (i.e. when the Lower Flammability Limit is exceeded for any given chemical). Please consult the specific MSDS for questions regarding flammability limits.
