If odours and dust get on your nerves, you’ll love this air purifier from AEG. It’s designed for medium-sized rooms up to 38m2, leaving the air in your lounge as clean and fresh as a coastal breeze. With a minimum noise level of 17dB, it’s really quiet too. This model also comes with 9 speed settings, so you can either have it on low as you’re going about your business, or crank it up high when the dogs get back from the park. Whatever you decide, the smart monitoring feature is always on hand if the speed needs adjusting – which it will do automatically if it senses the air quality is poor. And because AirSurround tech creates a spiral movement that covers the entire room, there’s nowhere for even the tiniest particles to hide.
