What Are Box Fans?

Box fans are large portable fans which are usually square or rectangular in shape. The ‘box’ contains a propeller blade that circulates air which is encased by a grill or metal lattice at the front and back. Designed to encourage air flow, such fans are usually strategically placed on window sills and doorways. So they can assist ventilation by drawing cool air from one area to another.

A box fan could be a great appliance to add to your home. It is budget friendly, environmentally friendly and easy to maintain. Some main features to consider when buying a box fan are its size, airflow in cubic feet per minute (CFM), noise and remote control options.

Box Fans vs Tower fans

Now that you have a basic idea of what box fans are, it is time to introduce tower fans. And to compare the two to give you a better idea of which appliance most suits your needs.

Tower fans like box fans are portable in nature. However, instead of the traditional propeller found in the box fan, tower fans consist of a series of small blowers set in a vertical unit. Tower fans are popular in Europe and Asia where central conditioning is not as widely used as in the American continents.

Design Considerations

While box fans come in a basic rectangular shape, tower fans come in an entire range of sizing options. And have the advantage of taking up less floor/desk space. Since they’re sleeker, they can fit into narrow corners and won’t compromise on the aesthetic nature of a room. They can, in fact, add something to it.

Pricing Options and Affordability

Box fans are a much cheaper option than tower fans, but they’re also less versatile and flexible. There are a lot of pricing options available. Tower fans and lower priced fans usually have fewer features than the higher-priced models.

Features

Tower fans often have cool features you can experiment with. Such as an ionizer, night light, variable speed settings, air purification and different operation modes.

They usually also come with a timer to determine how long the fan is to run for. Unlike tower fans, box fans lack the oscillation feature, and different wind modes let alone ionizers and other fancier features. Box fans perform the function they are designed for. A powerful airflow in the chosen direction.

Maintenance

Since they’re cheap, box fans can be easy to replace, and spare parts are readily available. Due to their basic design, box fans can be fixed up at home with the help of the provided instruction manual. If a tower fan malfunctions, it needs to be fixed by a professional electrician or sent to a professional service. Since they are built more intricately.

Cleaning Box Fans

Over time, the blades on the box fan tend to accumulate a layer of dust if they aren’t being used regularly or if they are left out in the open. Hence, it’s a good idea to clean your box fans every now and then. So that dust particles are kept out of your home and so that the motor runs smoothly as it tends to get clogged by dust. This may cause the appliance to overheat and catch fire in extreme cases.

With a little care, you can keep your appliance operating well beyond the expected duration. To clean your box fan, you need a few simple tools such as a screwdriver, a vacuum cleaner, and a damp cloth.

You will want to start by removing the cord from the power source and then unscrewing the grills from the back and front using your screwdriver. Most box fans have 12 screws in place.

Next, you should wash your grills by using a high-pressure detachable shower head to blast most of the grime off. Pull out any clumps of accumulated animal hair and leave to dry.

As for the motor and blades, first, you should wipe off any obvious dust with a cloth and suck dust out of crevices with a vacuum cleaner hose (with crevice attachment). Don’t go near any copper wiring as it may get damaged. Go over the blades with a damp (but not completely wet) cloth and leave to dry. Once that’s done, reassemble the appliance and observe the improved air flow.

Conclusion

Box fans are an energy efficient way of improving natural ventilation and cooling spaces. There are lots of models available in the market nowadays, and it can be hard to come to a decision without proper research. We hope our review of top products will help you choose and maintain a box fan that best suits your needs.
