Types of exhaust fans:
There are basically modes to operate the exhaust fan:
- Passive exhaust fan.
- Active exhaust fan
Passive exhaust fan:
Passive exhaust fans used to run at low speeds and which made the fan use less power. They are able to offer passive ventilation which is not considered as effective but they are much more energy efficient. You can easily run the fan for the whole day without worrying about the increase in your electricity bill.
Active exhaust fan:
The active exhaust fan I used runs at high speed and which makes the fan use more power. they are able to offer active ventilation which is not efficient but they are more consistent. Using the active exhaust fan for a whole day will have a slight increase in the electricity bill.
The electricity used by the exhaust fan and its efficiency are based on the cubic feet of air that the exhaust fan replaces in a minute.
Electricity used by an exhaust fan:
The electricity used by an exhaust fan depends upon the number of hours the fan is Run, its size, the area it has to ventilate, and the extra features found in the exhaust fan.
- The exhaust fan which does use natural gas will cost up to 1.32 per 1000 BTU or it can cost upto 0.086 per kWh.
- The electricity used depends upon the efficiency of the exhaust fan as it can be as low as 0.013 per kWh and the cost of using the large size of exhaust fan is upto 0.129 or it’s up to 0.98 per hour.
But if you are using an old fan then it will consume more power because as time passes it will take time to settle between blades and motor in the starting. This situation mostly happens if you do not use the exhaust fan for 24 hours then the dust and oil get mixed and it makes it difficult to start the fan. So maintaining the exhaust fan helps you to reduce the cost to run a bathroom exhaust fan. The wattage used by exhaust fans is from 5 Watts to 25 watts and it can be as high as 60 watts for a commercial system.
Comparison between the kitchen and the bathroom exhaust fan:

The kitchen exhaust fan runs from 40 Watts to 90 words when they are used in residential areas and are able to replace from 50 to 140 liters of air per minute and 60 to 120 watts of exhaust fan for commercial use are able to replace 100 to 350 liters of air per minute.
Bathroom exhaust fan:
The cost to run a bathroom exhaust fan for 24 hours is from $0.85 to $23.5 per day which depends upon the size and power the exhaust fan uses. The cost is also used to spend on the fan repair and maintenance, for example, if a fan is a residential exhaust fan if it breaks down and needs to be replaced and it will range up to $20. A good quality exhaust fan will cost from $50 to $70 and can be used for up to 2 years. But the commercial exhaust fan does cost more for repair and maintenance.
