The Bloomfield BLM2I-302579 Fryer Pre-Filter Hood helps capture grease and airborne particles to support cleaner and more efficient kitchen ventilation. Designed as a universal 16\" x 20\" x 2\" pre-filter, it fits compatible commercial hood systems and serves as the first stage of filtration by trapping larger grease particles before they reach the primary hood filters. This helps improve airflow, reduce grease buildup within the ventilation system, and support easier maintenance. Built for dependable performance in busy foodservice environments, the filter contributes to cleaner operating conditions, extends the service life of downstream filters, and helps maintain the overall efficiency of commercial kitchen exhaust systems.
