Breathe air as fresh as the English countryside with this purifier from Hoover. It’s designed for rooms up to 110 square metres in size and uses HEPA filters to remove pollutants from your home – which is perfect if you suffer from allergies or seasonal hay fever. The Auto mode does the hard work for you too, by automatically monitoring the air quality then adjusting the fan speed to suit. And because it comes with Wi-Fi, you can connect the purifier to your smartphone for regular updates on the filter, room temperature and humidity levels. This model also has a quiet sleep mode, so you can have it running in your bedroom without it waking you during the night.
