Grease Filter
Grease filters commonly found in range hoods or above-stove microwaves are critical for trapping grease, oil, and other particles during cooking, helping prevent buildup in the exhaust system, which can be a fire hazard if exposed to flames.
Optimal
The filter is clean, functioning effectively, and poses no risk of fire or airflow obstruction. Maintenance is up-to-date, and the filter ensures safe operation of the range hood or microwave vent.
Cautionary
The filter is visibly clogged or greasy, which reduces airflow and increases fire risk over time. There’s no immediate danger, but it should be cleaned or replaced promptly to restore safety and efficiency. Allowing this to persist without attention could increase fire hazards.
