The American Metal Filter Range Aluminum Grease Filter. This replacement range hood filter is designed to capture grease, airborne cooking particles, and contaminants generated during everyday food preparation. It works by allowing air to pass through its layered aluminum mesh, which traps grease while supporting proper airflow through the ventilation system. Designed for compatibility with select range hoods, it helps protect internal components from grease buildup and supports efficient exhaust performance. The durable aluminum construction is lightweight and easy to clean, making routine maintenance more convenient. Replacing a worn filter can help improve ventilation effectiveness and contribute to a cleaner cooking environment.
