Only when the surface of the blade is smooth is it able to throw air easily.
If there is dust on the fan blade of your house, then clean it as soon as possible. A dusty fan may seem normal to you, but it directly drains your pockets and also increases the electricity bill. There is complete science hidden behind this too, now let us understand it in simple language. Fine particles of dust also reach the house along with the air coming from every open part of the house. They may not be visible, but when the number of these particles increases, they start appearing as a layer of dust. When you touch it, it becomes clear that dust has settled on a particular part. Same is the case with fans also.
Now the question arises that how does a small amount of dust affect money? The work of providing air is done by three blades installed in the fan. If they are not cleaned from time to time, a thick layer of dust starts accumulating, especially on their edges. Most people do not clean the fan even in 3 months. This is where the biggest mistake occurs.
How does a slap feel?
The job of the fan blades is to throw air. When the surface of the blade is smooth, it is able to throw air easily. For this, it becomes easier to cut the air and throw it down. But when dust gets on it, its surface becomes rough. As a result, as resistance increases it becomes difficult for it to throw air. This is the reason that after cleaning the fan of the house, there is a feeling of getting many times more air than before.

When air accumulates on the blades of the fan, its ability to throw air reduces. As a result, the motor has to work harder. Then the speed of the fan is increased, but due to dust the efficiency of the blades has reduced. The fan has to work harder.
More load is applied on the motor than before so that the same speed is maintained. The motor overheats when the load increases continuously for a long time. Due to which its lifespan also decreases and in case of breakage it incurs huge expenses. Many times the cost of repairing is so high that it is advisable to buy a new fan. The expenses don’t stop there. Electricity bill also increases in other ways.
How does electricity bill increase?
When the capacity of the fan decreases, other means are used for air. Like AC, cooler and wall fan or other options. Using them with fans increases the electricity bill of the house. The direct effect of which is visible in the form of electricity bill. As a result, along with the danger of the motor blowing, the electricity bill increases and one has to shell out more money.

What to do now?
Dust not only reaches the fan but also reaches the motor part. Clean the fan and its blade with a dry cloth every 15 days. The less dust, the more the wind will throw. The report of fan manufacturing company Cropton says that to maintain the performance of the ceiling fan, it is necessary to clean it.
A 0.5 mm thin layer of dust on the blade portion can reduce its aerodynamic efficiency by 5 to 10%. This drag causes more stress on the motor, which produces heat and consumes more electricity to increase air flow.
