As lockdown descends on cities across the world once again, Dyson urges people to consider their indoor air pollution levels at home. Dyson purifier data collected from initial lockdowns in 14 cities globally indicated higher PM2.5 levels during lockdown compared to post-lockdown, highlighting the impact that spending more time indoors may be having on exposure to pollution.
Outdoor data collected over the same period with Dyson’s portable air quality backpack showed participants were exposed to lower NO2 levels during the lockdown period. This is likely due to the reduction of vehicles on the road during lockdown, as traffic is a common source of the pollutant.
Alex Knox, Vice President of Environmental Care at Dyson said:
“As people are spending more time indoors, cooking and disturbing household dust, it’s not surprising that our purifier data revealed an increase in PM2.5 pollution levels indoors. Raising awareness and educating people about air quality is such an important part of what we do at Dyson. The more information we get about it and the impact it has on people, the more we can work towards resolving some of those issues.”
In response to the lockdown restrictions of the COVID-19 outbreak, Dyson equipped nine individuals in eight cities around the world with its air quality backpack to understand lockdown’s impact on individual exposure to air pollution. Participants included London’s A&E and TV Doctor Alex George, Singapore’s Actor and Host Bobby Tonelli, and Toronto’s Nike Master Trainer Jennifer Lau.
Re-working existing technology used in Dyson air purifiers, the air quality backpack is a portable air-sensing device. Armed with on-board sensors, a battery pack and GPS, it is able to measure air pollution data on the move.
