A new study released this week reveals that ultrafine particle pollution is on average 3.5 times higher inside the home than outside – and in one case peaked at 560 times higher than outdoors.
The Global Action Plan studied four properties around the UK and found remarkably similar patterns of ultrafine particle pollution. Their data showed that outdoor air pollution adds to indoor air pollution, building up in the home, and taking longer than outdoors to disperse.
Says Chris Large, Senior Partner at Global Action Plan: “This year’s Clean Air Day 2019 we are placing a spotlight on the fact that air pollution isn’t just a problem on our streets, but in our homes too. You can’t just close your door and shut out air pollution.”
