These DH2 ductless hoods use stackable carbon filters to remove certain gases, solvents or radioisotopes. HEPA filters can be added to trap particulates.

Paramount Ductless Enclosures are self-contained work stations, also known as ductless fume hoods, that use carbon filters to rid the laboratory of annoying or unsafe concentrations of organic solvents, formaldehyde, acid gases, ammonia, or radioisotopes. Unlike traditional fume hoods, they require no ducting so they can be moved from lab to lab. Paramount Ductless Enclosures are capable of using both carbon and 99.99% efficient HEPA filters for removing gaseous and particulate contaminants. Filters used in the Paramount are sold separately and come in seven types Ammonia-Amine, Acid-Sulfur, Organic Vapor, Formaldehyde-Formalin, Radioisotope, Mixed Bed and HEPA.
