Dear coll eagues:

< /span>

We are in the process of building a new Laboratory and contemplating between using Dustless Fume Hoods vs. Ducted Exhaust Hoods. W e will be using a variety of hazardous chemicals including carbon disulfide , acetonitrile, toluene, benzene, some carcinogenic suspect chemicals, hydr ogen sulfide and sulfur dioxide gases.

I ap preciate sharing your experiences with ductless fume hoods and whether you recommend these type of hoods for hazardous chemical work using the aforeme ntioned chemical examples as well as advantages and disadvantages of these hoods vs. the ducted exhaust hoods (safety concerns, costs, maintenance, et c.)

Thanks,
