How to choose the best box fan?

Even though a box fan is not very difficult to choose and most of them come with similar specifications, putting a little thought into choosing one will take you a long way. Choosing a box fan with the specifications tailored for your needs with not only make the whole experience more pleasing but will also ensure long-term use of the product topped with the best value for money. Here are a few features that you should take note of while looking for the best box fan.

Size

The majority of the box fans on the market have blades that span over 20 to 21 inches in diameter. Fan systems that come with smaller blades mostly feature two fans side by side. At this point, you should know that the larger the diameter of the blade, the bigger the area that the fan can cool efficiently. However, while choosing a larger box fan, ensure that you have ample space to put it in.

CFM

CFM stands for cubic feet per minute which actually indicates the airflow of the fan and its performance. Most manufacturers don’t mention the CFM values in the description of the product. However, with some research, you will be able to get a note of it. CFM is directly proportional to the fan’s power.

Speed option preferences

Most box fans come with a 3-speed setting dubbed high, medium, and low. They are either equipped with a knob or an electronic control system to choose the speed. However, some inexpensive ones also come with a single or 2-speed setting. Where this does not affect the performance of the device, it does relate to how much control you have on the fan. A 3-speed setting gives you more options to customize the airflow according to your requirements.

Noise

If you are looking for a box fan for your room or your office, the last thing you need is something that sounds like a jet engine. Some fans produce a loud whirring sound that cannot be classified as white noise and after some time it just becomes a nuisance. Hence, you might want to steer clear of such products. Many box fans that produce a calming white noise are currently available on the market. If you want something for your home, you might want to choose one of those.

Controls

Fan controls are the most important yet most neglected part of the system. If you are looking for a ceiling or window box fan, you might want to invest in something that comes with remote control. This will make it easier to change fan and temperature settings. Otherwise, every time you feel the need to change fan settings, you will have to either stand up on a chair or walk all the way to the window. Other than this, if you are looking for a simple box fan, go for the one with front-facing controls. Rear-mounted controls almost always require you to move the device to reach them.

Removable grill

Box fans throw out air at a high speed. Hence, they become a hub for accumulating dust. Removable grills ensure that you can detach them and clean the fan from inside to prevent allergens and tiny particles of dust from roaming in the area. Moreover, a removable grill can be easily washed, brushed, and dried.
