00:00 Air quality around the world is getting worse by the day.
00:02 There's no doubt about that.
00:04 However, a new report indicates that in your home,
00:06 air depreciation is likely also happening,
00:09 and it could be far worse than you might imagine.
00:11 This is Ken Armstrong, an air quality scientist with Dyson.
00:15 Air quality indoors is actually worse than air quality outdoors.
00:21 That's true for 11 months of the year.
00:23 It's pretty normal.
00:25 When you think about it, you spend a lot of your life indoors.
00:30 You spend a lot of your life in your home.
00:31 It's where you sleep.
00:33 And the impact of air pollution will be how much there is,
00:37 how concentrated it is,
00:39 but also how long you spend exposed to it.
00:42 According to him, major contributors to poorer air quality include cooking,
00:46 as gas stoves are known to significantly increase harmful material in the air.
00:50 However, carpet and furniture can also trap particulate matter,
00:53 which can be released when in use.
00:54 And pet dander is a significant source as well.
00:57 And according to their data from some 2.5 million air purifiers,
01:01 those indoor particulate levels are actually above
01:04 the World Health Organization's long-term exposure guidelines.
01:07 What the data tells us is that small particulate pollution,
01:12 so that's PM 2.5, really small particles,
01:16 are more prevalent indoors than outdoors.
01:19 When we start to think about why that might be,
01:22 all the outdoor sources of air pollution can potentially come into the home
01:28 through ventilation, through cracks around windows, under doors, etc.
01:32 They add that those PM 2.5 levels are not only highest six months of the year,
01:36 but they are also highest at night, when most people are at home in bed.
