Steam and smoke from cooking release greasy particles. These particles can attach to the exhaust fan blades, housing, and other parts, generating a thick grease film. Grease can block airflow, impair exhaust fan effectiveness, and promote bacteria and other impurities.

Grease accumulation in a kitchen exhaust fan can cause reduced airflow, noise, aromas, and grease on the blades, housing, or filters. If you see these indicators, immediately clean your kitchen exhaust fan to avoid future issues.
