Grease filters shall be ______.

Grease filters shall be ______.

• A. Unlisted
• B. Listed
• C. Approved
• D. Certified

Answer: (B)

Grease filters used in commercial kitchen ventilation must be listed. Listing means a recognized testing laboratory has evaluated the filter and documented that it meets the required standards for use with grease-laden air in hoods and ductwork. This gives fire safety assurance: the filter is designed to withstand the heat and grease load, maintains its integrity, and fits with standard equipment. Unlisted would lack this independent verification, so it wouldn’t meet the safety expectation. Approved and certified are less precise terms in this context; listing is the formal, recognized status that NFPA 96 relies on for these components.
