When temperatures start to rise, you'll need help keeping cool and comfortable at home. An air conditioner is an effective option, but it can be costly to operate. A fan may be a more economical and efficient choice, and when it comes to affordability and convenience, it’s hard to top the box fan.
Box fans are one of the most common fan types available. If you want the right one for your home, you have to figure out the proper size, CFM, power settings, and other features that would make it most effective.
A box fan is a large, portable fan that’s usually square in shape. It contains a propeller blade that helps circulate air. The back and front of the fan feature a grille or lattice-work design to encourage airflow.
This type of fan is ideal for placing in a window or a doorway to help draw cool air from one area to another.
Box fans are usually large enough to cool bigger rooms. However, they’re still light enough to move from room to room, so you can place your fan wherever you need it most.
There are several reasons why a box fan can be such an effective cooling appliance for your home.
Easy setup: Many box fans come fully assembled. Simply plug the fan in, and it’s ready to cool your home.
Portability: While box fans can be fairly large, they’re usually rather light, and they don’t require an exhaust or drainage system like an air conditioner does. As such, you can easily move a box fan from one room to another.
Energy efficiency: A box fan uses less energy than an air conditioner. If you’re trying to minimize your energy costs, a box fan is an economical option.
Easy maintenance: Unlike an air conditioner, which requires you to clean and/or replace filters, drain water, and perform other maintenance chores, a box fan doesn’t require much upkeep at all. As long as you keep the blades and fan interior clean, it should operate well.
Budget friendly: A box fan demands less of your wallet than an air conditioning unit or central AC system. In fact, it’s one of the more affordable fan options in general.
Most box fans are roughly the same size, with a blade diameter of 20 to 21 inches. Because they’re fairly large, they require more space than some other types of fans. However, they typically provide more effective cooling power as a result.
Like all fans, a box fan’s power is measured by how much air movement it provides. Airflow is typically rated in cubic feet per minute (CFM), which helps indicate how quickly a fan can move the air in a given area. For example, a box fan that’s rated at 2,000 CFM will cool a room of 2,000 cubic feet in one minute.
To determine the cubic foot measurement of a room, multiply the height of the ceiling by the room’s square footage. So, for example, a 250-square foot room with an eight-foot ceiling contains 2,000 cubic feet.
Experts suggest that when choosing a box fan, you should look for a model that can move the air through your room in five minutes or less. But for the most effective air movement, look for a model that can get the job done in three minutes or less.
To allow you to customize the amount of airflow in your home, a box fan typically offers multiple power or speed settings. Most models offer three speeds: low, medium, and high. However, some box fans only offer two speeds: high and low. The more speed settings there are, the easier it will be to customize airflow in your room.
Box fans usually make noise when they’re working, though some models are louder than others. To determine how noisy a box fan will be, check out its decibel (dB) rating. If quiet operation is a priority, look for a model that emits 35 dB or less.
Some box fan packages include a remote control that allows you to operate the fan from across the room. With the remote, you can turn the fan on and off and adjust its speed.
Because most box fans are roughly the same size, their prices typically vary based on how many speeds they offer and their CFM rating. However, you can usually expect to pay between $15 and $60 for a box fan.
Lower-priced fans tend to have only two speeds and a CFM rating under 2,000. If you’re looking to spend the minimum, expect a cost of $15 to $25.
Looking for a mid-range option? A box fan with three speeds and a CFM rating between 2,000 and 2,500 will likely cost you between $25 and $35.
And if cost is not a factor, you may be interested in a fan with a CFM rating over 2,500. For a fan such as this, expect to pay between $35 and $60.
Q. Where’s the best place to put a box fan?
A. Many homeowners place their fan in an open window, where it can draw fresh air in from outside. You can also place the fan with the front portion facing outward, so it draws out the warm air from inside your home.
Otherwise, it’s a good idea to place the fan on a table, bookcase, or another piece of elevated furniture. Elevating the fan allows it to more effectively circulate air in the room.
Q. Can I use a box fan with an air conditioner?
A. Yes. A box fan actually pairs very well with an air conditioner. It can help circulate the cool air from the AC throughout your space to make it even more comfortable. In fact, running a box fan at the same time as the AC may allow you to raise your thermostat by three to five degrees. Place the fan near the AC vent for best results.
