Choosing the Right Filter for Your Ductless Hood

Ductless fume hoods employ an effective filtration method utilizing activated carbon filters which filter air in a dual capacity - physical adsorption and chemisorption.

Because activated carbon filters rely on both of these modes of filtration in order to provide optimal safety, the type of chemical reaction necessary for the chemisorption must be correctly identified.

Know Your Chemical, Find Your Filter

Finding the correct filter starts first with knowing the chemical components of the substance that will be handled. Once the chemical name and quantity have been identified, the proper filter can be chosen.
