Why Go For A Box Fan?

There are many methods of cooling or lowering the temperature in a room. What may suit you or your needs may not be very viable for another person. One thing, however, is that many people opt for the box fan, and this is because of the following advantages:

Easy To Use:

If you were to install an air conditioner or a central cooling system, you would need to bring down walls or partitioning, drill holes, insert a support system, and much more. This would require lots of effort and time. But with a box fan, you just purchase it, choose where to place it, plug it to power, and run it. It’s that simple!


The cost of an air conditioner can run into hundreds, if not thousands of dollars. Besides the cost of purchasing the kit, you also have to worry about the labor cost, permits, and of course, maintenance. A fan costs way less than an AC, and as you see in this review. You get high quality but very affordable units. There are no installation costs since the unit can be placed anywhere and is standalone.

Energy Efficiency:

Anyone who uses an air conditioner or a central cooling system already knows the high cost of power. In fact, the unit can account for as much as 30% of the total power usage. This can shoot through the roof during the hot months or summer. Fans, especially the modern types, are energy efficient. They feature a smaller, lighter, and more powerful motor. The design delivers better airflow, and it’s easy to vary the volume of air.

Portable And Convenient:

Box fans are lightweight and also small in size. You can carry it from one location to another easily and at any time. This is unlike air conditioning units which are permanently fixed and will only work in the specified location. After using the unit in the living room, you may move it to the bedroom when about to sleep, or on the balcony or patio as you relax.

Easy To Maintain:

Consumables such as the air filter in an air constrainer need to be changed after some time. The fins and grill require cleaning to remove dust, dirt and other debris. At times, this entails removing the panel or covers which can be a little laborious. A box fan doesn’t have a filter or other consumables, cleaning it are very easy, and you don’t need exceptional skills or calling an expert to service it.

Tips For Extending The Fan’s Lifespan

  • Choose The Right Size: While it may seem economical to go for a small fan, using it in a large room will shorten its lifespan and also affect its performance. The motor and fans will work extra hard to push the air, and the person on the furthest end may not experience the cooling. This may lead to the untimely death of the motor.
  • Run It When Necessary: Operating the fan continuously exerts unnecessary strain on the parts and will negatively affect its lifespan. It will also increase the energy consumption. When the room isn’t too hot, you don’t need to use the fan. You also should turn it off when you step out. A lower speed setting consumes less power and has a lower impact on the parts; you, therefore, don’t have to run it at full speed when it isn’t very hot.
  • Keep It Away From Moisture And Water: Moisture and water will damage the internal components of the fan, particularly the motor. It will cause the wires and other metallic parts to rust or corrode, or many cause a short circuit. The unit should be placed away from a wet environment, shouldn’t be used in the shower, or outside in the rain. Always make sure the power cord isn’t broken or frayed, and the plug is in good order.
  • Handle It With Care: Even the strongest fan will eventfully break or crack when dropped or banged against other objects too often. You should be careful when handling the unit and only move it when necessary. Placing it on a firm base and ensuring there is adequate space around it minimizes the chance of falling.

In Summary

Cooling the surrounding is inevitable, especially during the hot weather. However, if not careful, running the central cooling system or air conditioner will dent your pocket. A better alternative is using a fan. It will provide cool air, is more portable and can be placed in different locations, requires minimal maintenance, and is also more affordable. Box fans are among the top picks and are loved for their reliability, stability, and user-friendliness. To assist you in making a wise choice, we have listed the best box fans in the market.
