Commercial Grease Filter Exchange

Baffle filters are required by NFPA 96 for commercial kitchens. Unlike mesh filters, baffle filters force grease-laden air through a series of vertical channels that separate and capture grease by changing the airflow direction. They are more effective at grease removal, easier to clean, more durable, and — critically — they are UL-classified for fire safety. Mesh filters clog faster, reduce airflow, and are not compliant in most commercial kitchen applications.

Exchange frequency depends on your cooking volume and type. High-volume operations like charbroiling or wok cooking may need weekly or biweekly exchanges, while moderate-volume kitchens typically exchange on a biweekly or monthly cycle. We assess your operation and recommend a cadence that keeps your filters effective between professional exhaust cleanings. The goal is to prevent grease from bypassing the filter and accumulating in the hood and ductwork.

We supply the filters. On each scheduled visit, we deliver clean, UL-classified baffle filters sized to your hood and pick up the soiled set for off-site cleaning. You do not need to purchase, stock, or clean filters yourself. We verify fit and coverage on every exchange to make sure your hood is fully protected.

UL-classified means the filter has been tested and listed by UL (Underwriters Laboratories) to meet fire safety and grease extraction standards. NFPA 96 requires that grease filters used in commercial kitchen exhaust systems be UL-classified. This ensures the filter performs safely under the heat and grease conditions of a commercial kitchen. All filters we supply meet this requirement.
