Still working from home and missing the office aircon? Forgotten what it's like to sleep through the night without sweating? Yup, the hot weather has finally hit – so it's time to invest in a fan for your home. It'll help you get some kip at night and stay comfortable during the day.

Features: I was impressed with the number of features, and the scope for customisation. Choose between three oscillation angles up to 350 degrees, or turn it off. There’s a night mode that runs the fan on a quieter setting (although you’ll sacrifice power) and a timer so you can turn it off after certain intervals between 15 minutes and nine hours. The voice control is also a useful feature for these ongoing working-from-home times; it was a great time saver to be able to turn the fan on and off from my seat without having to get up and faff about with it (yes there’s a remote, but it’s never to hand when you need it, is it?). The Dyson Link app is new in India and it's the most confusing bit about this device. That's not to say it's not useful or easy to use, it's just set to higher standards than those prevalent in India. In the week and a half that I've used it, the app has never shown me acceptable AQI levels, settling to average at best.

How much is clean air worth?

The app also has a remote, that allows you to use the Cool Link from anywhere in the world. You can set schedules to turn the air purifier on at set times during the day. You can also turn the product on/off remotely whenever required. Aesthetics: Fans are never the most attractive things, but this one is the best-looking we’ve seen. Its modern, bladeless design and large cooling loop makes for a talking point. The bold, contemporary look might not be to everyone’s taste, but it fits in well with my modern white kitchen units. I also prefer the gold finish you get with the heater/cooler model more than the silver of the pure cooling types. The remote control sits neatly on the top, fixed with a magnet, so you won’t lose it. Once you connect to the Link and create an account, the app's main screen displays an image of a house. You can tap above the house to set your location, though this is really more like your general area. For instance, you can't select tiny townships in New Jersey across the river from Manhattan, but you can choose New York, New York. Once you select the closest area the app displays information about the outdoor air quality as provided by Breezometer, a start-up that collectsair quality and pollution data. You can also view the outside temperature, humidity, and time of day here. Performance: I was impressed with the cooling ability of this fan. Even on the lowest setting it provided noticeable cooling effects in my living room, which can get very hot as we have a large run of glazed doors that tend to trap heat. Using the night setting, my room stayed at a great temperature for sleep and the blades did not disturb me. Overview: This fan basically does it all – It’s a fan, a heater and a purifier all-in-one. So, if you’re looking for something all-singing-all-dancing, this is it. Dyson claims that this fan automatically senses particles and gases, capturing 99.95% of ultrafine particles, then pushes out purified air around the room (including formaldehyde, if that’s something that may concern you – although we’d hope not). This is helpful if you live somewhere where there’s lots of pollution, or if you suffer with hayfever.

Automatic mode is exactly what it sounds like. It activates the Pure Cool Link and adjusts the fan speed (1 being the lowest, 10 the highest) according to the room's air quality. It takes about six days for the Link to calibrate before it can sense higher than normal pollutants in an environment. Meanwhile, Night-Time mode simply sets the fan speed to 4 and dims the illuminated icons on the base. The purifier uses a 360-degree glass HEPA filter that can be changed manually when required. It's lab tested for 12 months usage but could last you anywhere between eight to 12 months depending on your usage. After running for about 8 hours a day for a week and a half, my unit says the filters will last for another 4159 hours (about 6 months). Features: It’s just a fan, but it does have two speeds. The main feature, I would say, is that it looks great. Unlike the other models we tried, this one’s retro design is made from sleek metal, making it far less of an eyesore than your standard plastic tower model. If you’re big on aesthetics, you might like it, then, but if you value technical features or having more control, it won’t be for you.Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions.

As for its namesake feature, Dyson claims the Pure Cool Linkremoves 99.97 percent of allergens and pollutants as small as 0.3 microns, including fumes from cleaning solvents, mold, and pet hair . In the process, it releases a steady jet of air. Unlike the Dyson Hot + Cool Fan Heater AM05 , there is no option for warm air. In terms of its humidifying function, our tester suffers from dry skin, and so upped the relative humidity target setting to 50% to see if it made a difference. Once it reached this level - which took a few hours - our tester noticed that the skin on their hands did feel softer. The increased humidity also improved static charge when getting dressed, which was a welcome bonus! Aside from its minimal, modern design, the tower has no distinguishing features. It's easy to wipe off and clean, and can be set to oscillate to help circulate air around the room. On the front of the base, near the bottom, is an embedded panel where you'll find a power button and an LED indicator that displays different symbols for when Wi-Fi is in pairing mode (flashing green), when it's connecting (flashing white), and when it's connected (solid white). When set to Automatic, the base will display a solid white A whilecleaning, and a solid green Awhen the air quality target has been met. A crescent moon symbolappears when the machine is inNight-Time mode. More on those modes in the next section. You can’t see air pollutants with the naked eye but they can cause respiratory problems or exacerbate issues like hayfever, for example. Obviously, we can't stop breathing, so a purifier can help,” says Jessica Le Dinh, a senior design engineer at Dyson.
