At full speed, 20-inch box fans consume an average of 86.5 watts. 20-inch box fans consume around 56 and 70.5 watts at low and medium speeds, respectively.
The Genesis 20 Box Fan, with a wattage of 53W, was the lowest measured wattage in the study. The greatest wattage ever recorded was 220W.
The average CFM observed was 1,750. CFM stands for cubic feet per minute and relates to how much air a fan moves. When looking for an energy efficient box fan, this is an important factor to consider.
Most efficient box fan and editor’s choice
The Brentwood 20 in. 3-Speed Box Fan appears to be the most efficient box fan at 60W and 2,294 CFM. The CFM value was obtained from Home Depot, which may be found here.
However, because of the lesser wattage, the ratings, reviews, features, and price, I’d recommend the Genesis Box Fan. Despite its low power consumption (the lowest 20-inch box fan wattage ever recorded), it produces a CFM of 1,800, which is more than enough for the great majority of people.
It’s also quite reasonably priced; check out the current Amazon price here.
A 20-inch box fan consumes how many amps?
A 20-inch box fan will draw 0.45 amps and run on 120 volts, resulting in a total wattage of 55. All box fans draw less than one amp, with the lower end of the range being between.1 and 1 amps.
Is it true that a box fan consumes a lot of electricity?
Let’s look at the cost of running box fans based on recent study into box fan wattage.
The typical box fan costs $0.011 per hour and $0.088 per night (i.e. 8 hours) to run in the United States. The average box fan costs 26 cents per day, $1.84 per week, and $8.15 per month if it runs 24 hours a day, seven days a week.

What is the maximum power consumption of a box fan?
Box fans are a popular form of cooling fan, with sizes ranging from a few inches in size for DIY cooling and ventilation projects to 20+ inches in size for larger rooms and smaller areas.
Many people question how much it costs to run a box fan because they can run for hours on end, day after day.
Smaller 7-10 inch box fans, which are used as personal cooling devices and are usually placed on a flat surface near the person, such as a desk, and bigger 18-20 inch box fans, which are frequently positioned on the floor and keep even larger rooms cooler and more pleasant to be in, are the most common.
Note: Box fans and other fans do not lower the temperature of the air they blow/exhaust; instead, cooling is accomplished through the evaporation of moisture from human skin, which is more intense as the air passes over the skin faster.
Smaller box fans (10 inches) use 25-30 watts at maximum air speed, but bigger box fans (20 inches) use 80-100 watts on average, though they can range from 50 to 200 watts.
Check the fan’s label, which is normally located on the rear side or on the bottom of the unit, and/or the Owner’s Guide for the exact wattage of your device.
How much does it cost each hour to run a fan?
Given the assumptions in the chart below, a home pedestal fan will cost between 1 and 2 cents per hour to run, or roughly $14.60 to $29.20 per year. The power output of pedestal fans varies greatly between models. The maximum power (measured in watts) of most home pedestal fans will be 45W to 75W, however bigger commercial pedestal fans may have outputs up to 300W.
The cost of using a pedestal fan is determined by the fan’s wattage and speed setting. It will, of course, be determined by the electricity rate you pay. We utilized a 3-speed pedestal fan with a maximum output of 70W in the example below. We also assume a 28.7c/kWh electricity rate.
In comparison to pedestal fans, modern ceiling fans use less electricity. Because pedestal fans oscillate and must spin at a quicker pace to provide airflow, they are larger than ceiling fans. While ceiling fans may save you a little amount of money on electricity, pedestal fans are much less expensive to buy and require no professional installation.
Is it true that box fans save energy?
Varying types of fans use different amounts of energy and produce different results.
The most important findings from a study of thousands of different fans, as well as a comparison of different fan types and the most efficient fan models, are shown here.
Here are a few spoilers:
- Ceiling fans are the most energy-efficient form of fan, moving the most air per watt.
- For personal cooling, box fans are the most efficient.
- The average cost of running a fan in the United States is $0.0059 per hour.

Is it more energy efficient to run a fan on high or low?
The fan consumes the same amount of current at different speeds, thus no. Because you are regulating the voltage drop when you control the speed of your fan. This voltage drop causes heat to build up inside the regulator, but it has no effect on the current flow or consumption.
Is it possible to run a box fan all night?
Do you like to use your electric fan to create white noise to help you sleep, remain cool, and save money on your utility bill? For all three of these reasons, electric fans can be a terrific way to sleep at night!
The good news is that you may safely leave most conventional electric fans on all night. There are several additional advantages to doing so.
Electric fans (the kind you’d buy in a store, like box fans, tower fans, and pedestal or tabletop fans) are generally safe and dependable. Electric fans like this do not pose any health risks and are unlikely to cause any electrical troubles.
Here are some of the reasons they’re great for staying up all night:
- Some fans (particularly box fans) produce a relaxing white noise that can be used to conceal noise while simultaneously promoting relaxation and sleep. For this reason, many individuals prefer the “white noise” produced by some fans because it helps them sleep better.
- Electric fans, for example, consume a fraction of the energy that a tiny window air conditioner does. (For example, 45 watts vs. 500 watts or more) This means you’ll save money on your electric bill.
- A fan’s soothing humming and/or white noise sound can assist in acclimating your mind and body to sleep time. It’s a healthy habit, similar to having a set nighttime regimen.
Having said that, if you’re going to run a fan all the time, you’ll want to be wise and safe about it. What exactly do I mean? Continue reading to find out more…
Is it expensive to run an electric fan?
Opening a bedroom window, sleeping without bedcovers, sleeping in different beds, freezing or filling a hot water bottle with ice water, and moving to a lower tog rating duvet are all other ways to avoid sleepless nights.
Other options for staying cool include:
- Before going to bed, take a cold shower.
- Close your bedroom windows and curtains during the day to keep the sun out.
- For a cooling mist on demand, fill a spray bottle halfway with cold water.
- Place an ice basin in front of a fan to make a homemade air conditioner.
- Before going to bed, chill a pair of socks in the refrigerator.
“When it comes to deciding whether or not to invest in a costly cooling system, the oppressive heat might cloud our judgment.” They can be expensive to acquire and operate, and they’re only beneficial on the few hot days the UK gets each year.
“The basic electric fan is still one of the most prevalent ways for dealing with the heat, and at around 7p each night, it’s a price that most people are ready to pay for comfort.”
How much electricity does a fan use?
As a result, fans have a greater impact on electricity expenses. An average fan consumes 75 watts per hour, whereas a tubelight consumes roughly 55 watts per hour. Older types and low-cost fans can consume up to 90 watts.
