Not all fans will oscillate, but they’re much better at circulating air if they can. For personal use, oscillation isn’t quite as important; however, the best bladeless fans will oscillate between 180 – 360 ° . This makes them more versatile overall, and better for use when more than one person is in the room. In terms of performance, it’s really good. I tested it on full power (10 fan speed), moving further and further away and I could still feel a steady airflow from several meters. Even the most basic fan will tend to have at least two speed settings; however, more advanced fans can have around 10. Also, for those who struggle with heat and air quality whilst nodding off, there is an eight hour timer so it can be programmed to automatically power down once you’re asleep.

When there are fewer fan speeds to choose from, the lowest setting will likely be the least noisy. However, it might not be very powerful. The more speed settings there are, the slighter the gradient between each one. Therefore, you might be able to get slightly more fan power, whilst still keeping a volume that you can comfortably sleep and work with. Modes Combining an air purifier with an oscillating fan, the U ULTTY Bladeless Fan with Air Purifier filters and cleans whilst it cools. Thanks to its DC motor – part of the reason this fan requires a little more investment – it also delivers that cooling airflow almost silently. Whilst it can't quite beat the Duux Whisper Flex Ultimate Fan on the 'virtually silent' front, it comes very close, especially when you consider what powerful airflow this fan can dish out. There's no hint of the dreaded droning noise that's associated with most fans, instead the only noise is of gushing air. Weighing in at 5kg, it’s also pretty lightweight. During the summer we’re constantly moving it from room to room, and you can do this with great ease.OSCILLATION - Experience even, refreshing breezes throughout your space thanks to the 120° oscillation feature of our powerful fan, designed for optimal air distribution. Like Princess’ traditional tower fan below, this connects to a user-friendly app and is compatible with voice control. It also feels sturdy and has a good range of air strengths. It's not tall though, and it only oscillates 50 degrees, meaning it works best when positioned nearby and directed at one or two people.

The EcoAir Kinetic's downsides are its size, which means it's not the best fit for a small home and can make storage a struggle if you're not blessed with a garage to stash it out of sight when it's not in use. It's also not the most portable fan in our round-up, weighing in at 5kg, the heaviest of all the fans we've tested. Our reviewer also wasn't entirely sold on its slightly dated appearance, although they were impressed by its build quality. Lastly, a panel of testers sit in a room kept at 30 degrees with each fan for half an hour and assess how comfortable it makes them (yes, really). Every model is then scored according to its performance, ease of use, design and product information. We tested this combination fan heater at home for over six months in a drafty living room and an enclosed porch. We also found it to be a great size to bring to the office for personal use by our desk. We loved how lightweight it was to move, and found the handle made it very easy to lift. The only issue we found is that heat only came out of the right side of the unit, and since it does not have an oscillation setting either, we had to move the heater around to get the right amount of heat distribution. However, we have no other complaints about this great little unit. Needless to say, mine still managed to go missing a few years ago, but getting a replacement wasn’t hard at all. I’d say when operating the fan from the unit itself, the buttons are a little awkward to press, so you really want to look after the remote – especially when using regularly during the summertime. 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.Introducing the revolutionary Vortex Air Turbo, the ultimate solution for year-round home temperature control.
