Dirty kitchen chimneys pose respiratory risks, say experts

A dirty kitchen chimney can worsen indoor air quality by failing to extract smoke, grease, and fumes, increasing respiratory risks.

Grease and oil accumulation inside the chimney obstructs airflow and reduces suction capacity within months if not cleaned.

Signs of a malfunctioning chimney include smoke lingering longer in the kitchen and persistent oily smell and grease.

Open-plan kitchens rely more on chimneys to prevent cooking pollutants from spreading to living areas.
