Name two common types of grease filters used in commercial kitchen hoods.

• A. Charcoal filters and paper filters
• B. Foam filters
• C. Mesh filters
• D. Baffle filters and mesh filters

Answer: (D)

Grease filtration in commercial kitchen exhaust focuses on capturing fats and oils before air exits the hood, preventing fire hazards and duct buildup. The two most common types used in vented hoods are baffle filters and mesh filters. Baffle filters are metal panels with angled baffles that force the grease-laden air to change direction; grease adheres to the surfaces and drains away, while the air passes through. They’re robust, handle heavy frying loads, and are easy to clean, which is why they’re widespread in busy kitchens. Mesh filters are made of fine metal screens that provide a large surface area for grease collection as air moves through; they’re lighter and can be easier to clean, but may require more frequent cleaning under heavy grease loads. Other options like charcoal, foam, or paper filters aren’t used for primary grease removal in vented systems; charcoal is for odor absorption in some recirculating hoods, and foam or paper filters aren’t standard media for grease capture in exhaust.
