Removable grease filters and grease removal devices not integral to a listed hood must be listed under which standard?

• A. UL94
• B. UL1046
• C. UL555
• D. UL1429

Answer: (B)

Removable grease filters and grease removal devices that aren’t built into the hood need their own listing to ensure they meet the right safety standards. The standard that applies to grease filters used with commercial cooking equipment is UL 1046. This standard covers the construction, performance, and compatibility of grease filters and removal devices with hood systems, ensuring they won’t become a fire or safety risk when paired with the hood.

UL 94 deals with plastic material flammability, which isn’t about filters. UL 555 and UL 1429 cover other aspects of ventilation and electrical components, not grease filtration; they don’t provide the specific controls and tests for grease filters. So the correct standard for these removable components is UL 1046.
