It’s a touch on the expensive side, but if you want a small cooler that can keep you comfortable while you work or sleep, this one is very effective.

This model will automatically purify the air, thanks to its sensors, dealing with dust, gasses and, new to this mode, formaldehyde. There’s a remote control, but you can use the app, Alexa or Google Assistant, too. We measured noise at a maximum of 48.5dB on the minimum setting, up to a more powerful 60.1dB on maximum – both measured from 15cm. This means that you can always hear the fan when it’s turned on, although it’s not too distracting. Unlike its competitors, the SmartAir Boost distinguishes itself with its dual power mode, allowing for both corded and impressive cordless operation up to thirteen hours. For those seeking a blend of functionality, convenience, and energy efficiency in a radiator fan, the SmartAir Boost emerges as the undisputed leader.Dimensions 26 x 27.5 x 67.5 cm, weight 6.45 Kg, water tank capacity 6 liters, power 55 watts, energy efficiency class A+, 3 speed fans, caster wheels, water gauge, 7-hour timer. Most fans can only be used in the hotter months of the year, taking up space when they’re not wanted. Not so with the Dyson Purifier Hot+Cool Formaldehyde. As well as being a powerful fan, it’s also a purifier and a heater, complete with thermostat. Tower fans are a great space saver but they often sacrifice power to get a slimmer body. Not so with the VonHaus 35″ Tower Fan, which manages to deliver some of the best fan performance that we’ve seen, both up close and across a room.

Plus, the Princess Smart Air Cooler costs a lot less to run than an air conditioner. We measured power and this air conditioner will cost around 2p per hour to run at current costs. When it comes to practical solutions for efficiently warming your home, the SmartAir Boost Radiator Fan is the best radiator fan you can buy. Its ability to redirect warmth where it’s needed most makes it an asset for those looking to optimise their heating without escalating costs. As anyone who’s tried to buy a new fan in the middle of summer can attest, there’s a ridiculous amount of choice out there and mostly from brands you’ve never heard of. Just take one look at the available wares of some of the biggest online retailers and you’ll know exactly what we’re talking about. Alongside these controls, there’s a timer (one, two or four hours) and oscillation mode (65° angle). If you don’t want to walk to the fan, then there’s also a remote control that attaches magnetically when not in use.

We found the heat mode to be reliable, too. This fan can help push a cold room into a comfortable space, and the thermostat helps cut down on electricity bills, as the heater will turn off automatically when the right temperature has been reached. This model uses a water tank, which lasts for between four and nine hours, depending on the temperature and humidity level. In either case, it’s enough water to get you through most of a hot night. Sliding the plastic disc up and down lets you point the air flow where you want it. There’s also a 90-degree oscillation mode, so you can sweep the air around. The benefits of the new system are three-fold. First, you can sit in a bubble of cooling air; secondly, on oscillation mode, the fan doesn’t blow bits of paper on your desk everywhere; third, the fan is far smaller than Dyson’s previous desktop models. Its power helps a lot: we measured air speed at 4m/s from 15cm away making this one of the most powerful fans that we’ve tested. Fortunately, this fan is very quiet, moving between 43.5dB on the lowest fan setting up to an acceptable 57.2dB on the maximum setting. With a neat remote control giving you easy access to all of the fan’s features, this is a top-quality fan for keeping you cool and your room feeling fresh. If you want a desktop version, go for the MeacoFan 650 Air Circulator.

A fan isn’t just about direct cooling, it’s about shifting stuffy, stale air around and refreshing a room. There’s no fan that can do that better than the MeacoFan 1056 Pedestal Air Circulator. A pedestal version of the desktop model, which is still available, this large fan has horizontal and vertical oscillation, so that it pushes air all around, giving full-room recirculation. As this is a portable model, you lose out on some features that bigger models have: you don’t get a remote, there are only four fan speeds and there’s no oscillation. If you need any of these options, look elsewhere, but if you want a flexible fan you can take everywhere this is the best model that we’ve reviewed. The biggest advantage of an air cooler over the air conditioner is the cost, a great air cooler will be significantly cheaper than an air conditioner. Most of the air coolers are also portable so you can move them around your place easily. Some of them are small enough to be taken on camping trips as well, all you need is some clean water supply and you are golden.

Air flow isn’t particularly fast. At full speed, just 15cm from the grille, we measured air at 1.9m/s, but the wind speed was unmeasurable by 1m. As this is a personal fan that physically cools the air, the evaSMART doesn’t need to blow air any faster. In fact, at times it felt too cold sitting in front of this cooler. Dyson fans all look so distinctive with their bladeless heads that you can put a hand through that theDyson Pure Cool Meimmediately looks different thanks to its ball head. The reason for the design change is that the fan uses Dyson’s Core Flow technology, which lets the convex surface direct a fine stream of air exactly where you want it, making it perfect for personal cooling. We found this a good fan for small- to medium-sized rooms. On its high setting, the fan reached an airspeed of 3.2m/s at a distance of 15cm. That’s good but there are more powerful fans that are better suited to larger rooms. At this speed, we found that the fan wobbled slightly, too. At 1m distance, the fan speed was still a decent 2.2m/s, providing a noticeable cool airflow. We were impressed with how quiet this fan was: at 15cm, we measured it at 66.2dB, and at 1m, it was just 50.3dB. Dimensions 16.5 x 16.5 x 16.5 cm, weight 748 grams, power 7.5 watts, voltage 110 volts, noise level 10 dB, color opaque white, cooler, purifier, humidifier. All fans can adjust the amount of air that comes out of them by adjusting how fast their blades spin: the slower they go, the lower the air flow. Having control over the air flow is very important for different situations, and where you sit. So, as our tests show, the slower the fan speed, the less the impact is at distance, so if you sit further from the fan or want to cool more people, you need a higher fan speed. Conversely, if you’re sitting at a desk and just want to cool yourself, then you can get by with a lower fan speed, which will also mean that you don’t blow papers around on your desk.
