5 advantages of going ductless
There is a great deal of fear associated with making the leap from traditional ducted hoods to ductless; however, more laboratories are recognizing the benefits of going ductless.
Here are the five advantages that a ductless hood has over other enclosures:
Flexibility: Ductless fume hoods are useful in hard-to-duct areas, such as the center or bottom levels of multi-level buildings.
Turnkey Operation: Installation expenses are far less than traditional hoods; no ductwork and remote blower are required.
Portability: Ductless hoods may be shared among several laboratories or stored when not in use.
Sustainability: They have no make-up air requirements, allowing them to be used in air-starved labs or to offset air needs of ducted fume hoods.
Green: Costly tempered air is not exhausted from the laboratory, resulting in lower energy costs.

DID YOU KNOW?
Under S_EFA 9:2010 – Recommended Practices for Ductless Enclosures (Scientific Equipment and Furniture Association)_ there are three categories of “ductless hood” or DH?
DH I: A ductless hood equipped with a filtration device designed to control non-toxic chemicals, nuisance odors and particulates.
DH II: A ductless hood capable of meeting all DH I requirements, and equipped with a filtration device designed to filter manufacturer-approved toxic contaminants up to filter breakthrough only.
DH III: A ductless hood capable of meeting all DH II requirements, and equipped with a filtration device designed to filter manufacturer-approved toxic contaminants beyond primary filter breakthrough by providing secondary back-up protection.
