When fan blades collect thick dust, they don’t move air as efficiently. The edges lose their shape slightly under the dust layer and airflow becomes weaker. You might feel like “ye fan toh hawa hi nahi de raha,” and immediately think of buying a new one or cranking the speed to full.
A good wipe or wash of the blades before hot weather kicks in removes all that drag. The fan spins smoother and throws better air at the same speed setting. It sounds small, but you can actually feel the difference when you sit directly under it.
Plus, you’re not raining dust on yourself every time the fan runs at high speed.
