You can breathe a sigh of relief knowing that this Dyson air purifier is keeping your living space fresh. It's designed to cover up to 27 square metres, making it perfect for medium-sized rooms. And while you're chilling out with a book, hit the oscillating function to circulate clean air all around. Plus, the HEPA filters put a stop to allergens that can cause sneezing and sensitive skin. You can also set the fan to switch off after a certain amount of time, just long enough to make sure the smell of that takeaway doesn't stick around. Want to switch up the settings? No need to get up off the couch, just grab the remote control and stay comfy
