Think the air inside your house is cleaner than the air outside? Worryingly, you’re wrong. In 2019, air quality tests* in residences across the UK found that the air inside had 3½ times worse pollution levels than outdoors – in fact, according to the Royal College of Physicians, indoor air pollutants cause thousands of deaths every year.
‘There’s so much focus on outdoor pollution and vehicle emissions that we barely give a thought to the air quality in our homes,’ says biochemist Dr Chris Etheridge. ‘And there’s also the temptation to assume that there’s nothing we can do, but simple measures can make a difference.’
