Can the fan cool a room?

The fan cannot change the room temperature; it just circulates air. However, the breeze of a fan on your body helps evaporate sweat, which makes you cooler. In a humid environment, the fans do not work as well as less sweat evaporates.

For this reason, you may want to consider purchasing a dehumidifier that will improve fan performance and make your room more comfortable. Increased air circulation can also prevent the feeling of suffocation in the room.

To actually cool the room, you need something that can lower the air temperature. Air conditioning is the main option in this case, but the second option is the use of an evaporative cooler. They have a water tank that evaporates slowly to help cool the air and work best in dry and hot climates.

How does humidity affect cooling?

Fans make you feel cooler, helping sweat to evaporate from your body. How efficient the fan is depends largely on how humid it is. When there is high humidity, sweat evaporates hard, so the fan does not help you cool down much. That is why on wet days we tend to think of them as hot and sweaty. Conversely, when the humidity is lower, it is much easier for evaporation to occur when the fans feel most efficient.

You can use this knowledge to your advantage and buy a dehumidifier for these hot days. With a dehumidifier that sucks moisture out of the air, the efficiency of the fans increases. The dehumidifier will also make the evaporative cooler more efficient.

Air conditioners can also act as dehumidifiers. So, if you have a portable appliance, but you think it is too strong to sleep with, you can turn it on before going to bed in dehumidifier or cooling mode and then switch to a fan at night. This way you get the best of both worlds: a cooler and less humid environment in which to sleep with a fan to keep you cool at night

What type of fan is right for you?

Tabletop fans are traditional models. They allow you to tilt the fan to direct the airflow; turn on the oscillation mode to allow the fan to move from one side to the other.

Pedestal fans look like high table fans and are designed to stand on the floor. They usually have larger blades, so they take up more space, but that makes them more powerful. With most models offering height adjustment, in addition to rotation and oscillation, pedestal fans are easier to configure for the perfect cooling breeze.

Tower fans take up very little floor space and blow air from a high column. To reduce the size, you sacrifice some power and also do not get height adjustments or rotation – just flicker. As a result, you may need to use a tower fan closer to you, but they are a great choice when space comes first.

What other options should I look for?

Noise is important, especially if you want to sleep with the fan on. We have measured the sound levels of each fan, both maximum and minimum, to help you decide.

A fan with a remote control can be a good option if you want to adjust the settings on the go. This is especially true in the bedroom, where you may not want to get out of bed to turn off the fan. In this regard, look for a fan with a sleep timer so that it turns off after a certain time.

More advanced options for high-end fans include air filters that help clean the air, or heating elements so you can keep warm in the winter.

Do evaporative coolers work?

Evaporative coolers use a water tank and a pump. As the water evaporates, it cools the air, leaving these fans to blow out air that is colder than the ambient temperature: consider what it feels like to spray water on a hot day. The good thing about evaporative coolers is that they are cheaper to operate than air conditioning and open windows. The downside is that they do not work very well where it is humid and the water cannot evaporate.

Productivity also varies depending on the humidity level: evaporative coolers work best in very dry environments, where the effect of evaporation is also to increase humidity for a more comfortable environment. Fortunately, summers in the UK are usually hot, but not as humid, so evaporative coolers work quite well. However, they do not reduce the temperature in the room, as the air conditioner will work and works best when you are in the cooling line of the fan.

Do I have to buy a fan that is also an air purifier?

Air purifiers are a good way to increase the interior comfort of your home. They are designed to filter air pollution, including pollutants, allergens, dust and in some cases gases. By filtering them from your air, you get cleaner, cleaner air in your home, which is good for everyone, but especially for those with respiratory problems or allergies.

Although you can buy stand-alone air purifiers, this means that you end up with many boxes around your home. Having an air purifier built into the fan gives you a dual-purpose design. The main thing to watch out for is whether or not there is a diffuse mode in which air can be directed from the back of the fan: this way you can use the cleaning functions during the colder months without getting a blast from cold air.

Is smart features worth it?

Smart features do not change the ability of the fan, but allow you to control them automatically via an application and possibly by voice via Amazon Alexa or Google Home. The benefit for most people is laziness, as you can control your fan without having to stand up and move. However, some models allow you to do some smart things. For example, with Dyson’s smart fans, you can program automatic procedures, such as automatically turning off the fan when a motion sensor detects that no one is in the room, which helps save energy. The disadvantage of smart fans is that they are usually more expensive. A cheap solution is to use an old fan with physical controls connected to a smart plug: this will not allow you to choose the fan speed, but will allow you to turn the fan on and off remotely.

What should I look for with fan speed controls?

All fans can regulate the amount of air that comes out of them by regulating the speed of rotation of their blades: the slower they run, the lower the air flow. Airflow control is very important for different situations and where you sit. So, as our tests show, the slower the fan speed, the smaller the impact from a distance, so if you sit further away from the fan or want to cool more people, you need a higher speed. fan. Conversely, if you are sitting at a desk and want to cool yourself, then you can handle a lower fan speed, which will also mean that you will not blow paper on your desk.

There is also a difference in noise at different fan speeds, with lower fan speeds being quieter and faster faster. This is important at night, when you may want a slower, gentler, and quieter fan speed rather than the roar of full cooling power.

Generally speaking, the more fan speeds a fan has, the greater the difference between minimum and maximum power, giving you a greater range of cooling options. Some fans, on the other hand, have low cooling speeds, so you get little difference between full power and low power.
