The choice to buy a tower fan is one of those instant gut decisions. It’s unbearably hot, you slept horribly last night, so you go out and buy one as a matter of urgency. The only problem being that everyone else has the same idea at the same time and Argos becomes a battleground of competing shoppers, trying to buy anything that's left over - one plus point, at least there's air conditioning in there. A better plan is to order one online before you desperately need it. Even then it really pays to do a little research before you buy, find out about the additional functions and understand a little bit about how they work. Tower fans typically cost between £25 and £100, putting aside Dyson's models that cost many times that, and although even cheap ones work fairly well you may miss out on some very handy extras. How to buy the best tower fan for you To start, it’s worth making one thing very clear: a tower fan is not an air conditioning system.

While air conditioners actually cool the air, tower fans simply push the air around. Obviously, this means that even the best tower fan can’t compete with an air conditioning unit, but then they’re also much cheaper - both to buy and to run - so it kind of levels out. In the UK, with our comparatively mild, dry summers, an air conditioning unit is probably overkill.

Top 3 best laptop cooling software that will improve the performance. It helps keep your system cool by adjusting your CPU’s fan speed. Automatic and manual. Tower fans can be a great way to cool off in the summertime, but only if you choose quality products. The best tower fan should be quiet, it should have several.

That means that when the fan stops, so does the cooling, which is why noise is such a big deal with tower fans. While anyone can put up with the constant hum of a fan during the day, it can be a real pain when you’re trying to get some much-needed sleep, and as neither heat nor noise aid sleeping, you often need to reach a compromise. That’s one of the first things to look out for. Most tower fans have a night mode to reduce the noise but still provide some cooling. Often these can be operated on a timer, so that you can have it automatically switch off once you’re fast asleep. There’s also oscillation - even the cheapest tower fans tend to rotate in order to cool the room section by section.

How far these rotate varies from fan to fan, so it’s worth thinking about your room layout in advance. It's not just rotation, though, as even when stationary, different fans expel air at varying angles, with some producing a more directed blast, while others have more of a spread. Most tower fans come with a remote control so that you can manage airflow without unsticking yourself from the sofa. This is really handy if you want to turn it up or down from bed or even just pause the fan while you take a phone call or listen to something on the TV. How we test tower fans When testing a tower fan, we’re looking at three main criteria: power, range and noise. That is to say, how much airflow the fan is putting out, how wide the distribution is and how noisy the whole thing gets. So, in the Expert Reviews labs, we place the fans in exactly the same setup, and test each point individually.

By adjusting the angles, we can get a pretty good idea of how wide the airflow goes before it ceases to offer any real cooling benefit. We've also looked at the angle of oscillation (rotation left-to-right) to see how well it can keep multiple people cool in a room.

Noise, unsurprisingly, is measured with a sound level meter. We carry out these tests at a variety of distances: one, three and five metres away, in order to replicate real world use in most UK homes. We carry out these tests at the highest setting, as well as the night mode (if present), and all of the objective measurements are backed up with a ‘human eye’ - how does it feel, sound and look?
