An Electric Fan Is a Great Summer Tool

A powerful electric fan is a great summer tool. Pointed at a smoke-filled room it can help clear the air.

Randomised trials examining the effects of fans on health during heatwaves in high, middle and low income countries are of interest. This review will include studies of both handheld and pedestal/table fans.


Before the advent of electric fans, people kept cool by manually fanning themselves. Portraits of our ancestors often dehumidifier show them being fanned with cloth or ice by someone else. But this could be tiring and time consuming. And then there were the hot, sticky summers.

The aim of electric fans is to increase heat loss via convection, radiation and evaporation. The effectiveness of fans at doing this depends on the temperature and humidity conditions. For example, at very high temperatures (35 degC) or high humidity, the directional flow of air from an electric fan may actually increase heat gain by blowing hot ambient air across the skin and possibly leading to heat exhaustion.

For this reason, some experts recommend not using fans in these temperatures. However, the evidence on this issue is mixed (Hajat 2010). Some studies have shown that electric fans can provide cooling benefits in these temperatures, but others have found that using a fan increases the rate of dehydration and heat illness in healthy young adults.

The uncertainty about whether electric fans are beneficial or harmful in the context of heatwaves needs to be resolved through further research. This is best done in the form of randomised controlled trials. These would help strengthen the evidence base on which health protection recommendations are made within national heatwave policies around the world.


Before electricity, fans were powered by alcohol, oil or kerosene. It was a time-consuming and tiring way to get the air moving in your home. Thankfully, the invention of electric fans has made it possible to move air much more efficiently and quickly.

Electric fans help to remove odors, smoke and dust from the atmosphere in rooms that are closed up. Using an electric fan can also help to reduce the growth of mold, mildew and bacteria in your home, especially when used in conjunction with other ventilation systems.

The ventilation effect of ceiling fans can be improved by optimizing their airflow induced by increasing their rotation speed. This will allow for a greater proportion of particles to be moved by the low gravitational force, while the majority of other particles are sucked into the fan.

In addition to cooling, the ventilation effect of an electric fan can be helpful in preventing dehydration during a heatwave. While sweating is a healthy response to heatwave conditions, excessive fluid loss can lead to dehydration. In fact, hydration data from workers in several European sectors show that on summer mornings, most people arrive at work objectively dehydrated.

While a stand-alone fan can help, an automatic radiator fan is more effective for your vehicle’s engine and cooling system. These electric fans mount directly onto the radiator and can be activated by a sensor that detects the temperature of your engine coolant. The sensor sends a signal to the PCM (Power Control Module), which turns on the radiator fan when needed.


The quiet effect of an electric fan promotes comfortable bedroom sleeping conditions. A quiet fan typically operates at a lower noise level than other fans and can be turned off or down to low settings for light sleepers. Some models are even bladeless to further reduce the noise produced by the motor.

In addition to a range of airspeed and power settings, some quiet fans offer convenient features like remote controls and automatic timers. They also include advanced technology that enables users to operate them via a smartphone app or voice activation with Amazon Alexa, Google Home, and Siri.

Many factors contribute to a fan’s sound production, including thermal and mechanical design. These elements can render even the best quiet fan noisy if implemented poorly or operated at high speed.

Some models feature a DC motor that produces 75% less heat than traditional AC motors. This helps reduce energy costs and carbon footprint while maintaining a strong cooling capacity. Other features, like directional oscillation and multiple fan speeds, make this fan ideal for a wide variety of room sizes and cooling needs. It also comes with a built-in aroma compartment for use with essential oils to enhance the cooling experience.

Saves Money

Unlike air conditioners that decrease the temperature of the air by using refrigerants, fans only require electricity to move the air. This means that they are an inexpensive way to cool a room in conjunction with open windows, avoiding the energy costs of air conditioning.

During warm weather, Alex uses the ceiling fans in his house to keep the temperature down and he turns on his central air conditioning as early as April. Adding an electric fan in the principal rooms of his home allows him to run his air conditioning for only three months of the year. In the long term, Alex will save hundreds of dollars per month based on his current energy usage.

Although a ceiling fan consumes relatively little energy, it is important to remember that the motor itself generates heat as it operates. This waste heat must be dissipated or it will increase the temperature dehumidifier wholesale of the room and consume more electricity. The best strategy is to use a fan when you are in the room and to turn it off as soon as you leave. This will help you develop good habits that will save energy and money in the long run.
