Choosing a ceiling fan or box fan is an important decision, and there are many factors to consider. You will want to know the CFM per watt, the design differences, and energy efficiency. Also, consider noise. Your dog will likely be uncomfortable with a fan that makes a lot of noise.

CFM per watt

CFM per Watt is a measure of the fan’s ability to move air per watt. Although manufacturers may not always provide this information, it is important to consider when choosing a box fan or ceiling fan. The efficiency of a fan’s airflow per watt is determined by its speed.

There are several factors that determine how much energy your ceiling fan or box fan uses. The fan’s age can also impact how much power it uses. However, most ceiling fans are energy-efficient when it comes to power consumption. You can also look into purchasing an ENERGY STAR-certified ceiling fan/light combo kit. These models can run 60% more efficiently than a conventional fan/light unit.

Design differences

There are several design differences between box fans and ceiling fans. One of the biggest differences is the number of blades. Although ceiling fans with five or six blades are more efficient than box fans, the number of blades in a fan is more about style than functionality. A four or five bladed box fan provides a more traditional look while a three bladed one is more contemporary.

Another important difference between ceiling fans and box fans is the amount of air they move. While both types move air, ceiling fans produce the highest amount of CFM per watt, while box fans come in second. Although a box fan is stronger, it can’t move as much air as a ceiling fan.

Energy efficiency

One way to calculate the energy efficiency of a ceiling fan or box fan is to look at the power factor of the fan. This is a mathematical calculation that determines how much electricity the fan requires to run at full speed. A fan with a power ratio of 1 will consume 100% of its rated power, while a fan with power factor of 0.5 will consume 50% of that power.

If you’re planning to buy a ceiling fan, look for an Energy Star rating. Although it doesn’t apply to all ceiling fans, it’s important to choose one that is certified. It will cost less to operate than a non-certified model. Also, smaller fans use less electricity than larger ones.


A noisy ceiling fan or box fan can be a sign that the fan isn’t balanced properly. This could be due to a loose or incorrectly installed part. It may also be caused by accessories that aren’t compatible with the fan motor. These accessories could include remote controls, fan speed controls, and dimmer kits. Make sure your ceiling fan is well balanced before you turn it on or unplug it.

If the noise is not being explained, you can disassemble the fan to inspect its components. If you find any loose screws or parts, tighten them. This may stop the noise. You may also want to clean the blades and other parts.


A ceiling fan or box fan can keep your home cool and comfortable. These fans are inexpensive and provide great ventilation. They can also help lower your utility bills. Before you buy one, there are a few things you need to consider. First, ensure it matches your home’s decor. A ceiling fan that is too out of place will reduce your home’s value. It may be worth hiring an interior decorator to help you choose the right style and color.

Another factor you should consider when determining the cost of your ceiling fan or box fan is the electricity rate in your area. The average American consumer pays $0.14 for electricity. Here are the average electricity rates for your area. In high-electricity areas, you can expect to pay between three and four cents an hour for your box fan or ceiling fan.
