How to Choose The Best Desk Fan
As much as it surprises us every year, summers in the UK can get pretty hot.
During a heatwave, the only thing we really want is to be outside enjoying the sun, but, alas, most of us still have to work.
There are few things worse than being stuck behind a desk on a boiling hot day – but at least there are compact, tabletop fans that can help keep us cool whilst the temperatures rise.
The best desk fans aren’t just compact, but they’re quiet enough not to be disruptive either. In fact, many of them can be useful for night time as well. The following tips will help you work out what sort of fan to look out for – they can vary significantly in design!
Decibel Noise Level
When working, noise can be a number one distraction. Whether at home or in the office, you don’t want any loud, gale-force disturbances interrupting your work.
Fans that are designed for desks are usually conscious of being quiet – their descriptions should mention how many decibels they produce. Be wary of fans that simply describe themselves as ‘quiet’ without a decibel rating, or customer reviews, to back them up.
Desk fans should ideally produce under 50 dB of noise, which is roughly equivalent to the hum of a refrigerator.
30 dB is considered to be on par with whispering/rustling leaves, whilst 10 dB is the sound of breathing.
As you might expect, desk fans are at their quietest on the lowest fan setting; therefore, expect the described decibel level to apply to the fan on its lowest speed, unless specified otherwise.
Fans with a lot of speed settings (over 10, for example) will have smaller gradients between each level. Therefore, you might be able to have the fan on slightly stronger, whilst keeping it at a noise level that’s suitable for work. If a fan only has four speed settings, the jump between each option will be greater and you may only be able to use it on the lowest option.
Choosing the Best Design
Desks fans can vary hugely in shape, size and style. Smaller models are best for crowded desks without a lot of space, whilst larger, more powerful fans will likely offer more cooling power.
Most desk fans are reasonably portable; however, there are some that are small enough to fit into a laptop bag or backpack. These are the options to go for if you’re looking to take your fan out of the house with you. Of course, they won’t have the strength of larger fans.
Standard desk fans should be easy enough to carry and manoeuvre between rooms in the house, meaning they can be used for sleeping as well as work.
One other important option to consider is safety. Bladeless desk fans have become popular in recent years because there are no spinning parts. This can be particularly beneficial if there are small children or pets around.
Design Features
Not all fans come with the same features. It isn’t unusual for them to have a choice of at least two speed settings (although some can have many more), but there are several other factors that can separate one fan from the next.
Timer Function
This is especially useful if you’re also going to be using the fan whilst you sleep. If the fan has a timer function, you can set it to turn off after a couple of hours. This will help save electricity but means you can still use the fan as you nod off.
Timers are described in hours. For example, if a fan has a 10-hour timer, it can be set to be on for up to 10 hours, and then turn itself off.
Remote Control
Some fans have a remote control which means their settings can be changed from across the room. There are many scenarios in which this can be useful, and it can make the fan a lot more practical to use.
Primarily, having a remote control can help make using the fan less disruptive, meaning you don’t have to get out of your chair, or out of bed, to change the settings.
Sleep Mode
Desk fans with a sleep mode should run quite quietly. A sleep setting won’t usually have a very powerful airflow, but it should be sufficient to keep you cool whilst sleeping – especially if it’s in close proximity.
Sleep modes can also be useful when working, especially if on a videocall, as they can be very quiet.
Oscillation
Not all desk fans oscillate. Smaller models are less likely to oscillate as they are more focused on aiming the air directly at you. However, larger fans oscillate in order to move air around the room.
This can be especially useful if you are trying to increase the reach of an air conditioning unit – oscillating fans don’t cool down the air, but they can help circulate colder air from a window or air conditioner.
Some fans oscillate both vertically and horizontally, whilst others only rotate from left to right.
Power Supply
Desk fans can be powered either by a standard mains-power connection, or a USB connection.
USB fans tend to be smaller than other models, but they can be beneficial if travelling or using the fan for personal use.
A main-powered fan will naturally need to be positioned close to either a power socket or an extension cable. USB-powered fans have the potential to be entirely portable if they are attached to a USB battery pack.
If you are worried about the cost implications of running a fan for a long time, USB fans can even run off solar-powered battery packs which means no mains power is used (and running the fan is free).
Desk Fan FAQs
How can I be sure that a desk fan won’t disturb me when I work?
There are two ways to check if a desk fan will be sufficiently quiet. The first thing to do is check the decibel rating of the fan.
Those that emit less than 20 dB of sound will be barely noticeable. Even 30 dB is considered to be very quiet – creating as much noise as the hum of a fridge.
Secondly, it can be useful to check customer reviews online, as these can give a real indication of how quiet or not a fan is in practise. Bear in mind that a fan will be quietest on its lowest power setting – and this can be where the decibel readings are taken from – so reviews can help give a better overview of the fan’s overall performance.
Do desk fans use a lot of power?
If you’re concerned about your electricity bill, choose a fan with an energy efficiency rating of A+++. The specific amount of power used will depend on the model of the fan, but those with a good energy rating shouldn’t be too expensive to run.
If you choose a personal desk fan that uses a USB cable, you can keep a better eye on how much power it is using by running it off a USB battery pack. If you have a battery pack that charges using solar energy, you could run a USB fan without using any mains electricity,
What is the ideal temperature for working?
Productivity tends to wane when we’re either too hot or too cold, but studies have suggested that most people work best at a temperature between 16°C and 24°C. Any hotter or colder and you may struggle to concentrate – although this can depend on plenty of other factors too, of course!
