Dyson Air Quality Backpack

Re-working existing sensing technology used in Dyson air purifiers, Dyson’s air quality backpack is a portable air sensing device which collects air pollution data on the move. With on-board sensors, a battery pack and GPS, Dyson hopes to use this sophisticated technology to offer insight into personal exposure to air pollution and how to avoid it.

One sensor in the backpack measures temperature and humidity. The other two detect pollutants including NO2, VOCs, PM2.5 and PM10. Unique algorithms process the data, which is combined with information gathered from the on-board GPS to create reports on air quality.

"Our engineers have developed intelligent sensors using knowledge derived from years of experience and research in air cleaning technology. Using our unique algorithm to process detailed reports of air pollution exposure, this innovative technology allows us to monitor air quality indoors, outdoors and on the move. What’s more, it all fits within a backpack."

Alex Knox Vice President of Environmental Care at Dyson

Investigation of daily air pollution exposure for Delhi NCR-based mother

Dyson engineers analysed the findings by pairing the air sensor and GPS data from the backpack with Karuna’s diary entries, where she documented her activities and observations in the period wearing the air quality backpack. This allowed them to understand what may have caused the pollution and how Karuna might be able to lower her exposure in the future.

Data showed average personal exposure to PM2.5 indoors to be over four times worse during November

The Phase 2 pollution data collected in November indicated a significant increase in PM2.5 levels, with average levels rising by 459%*. These levels remained high both indoors and outdoors, irrespective of the activity taking place.

Karuna’s Phase 1 data highlights how air quality can be impacted by daily activities. Actions like frying food in the kitchen increase PM2.5 levels by five times, while visiting an outdoor market caused NO2 levels to rise to 2,500ppb, which registers as very poor on the Dyson AQI scale. Chauhan’s exposure to PM2.5 and NO2 pollution peaked while she was driving on the Expressway.

    Pollution levels remained high, highlighting that green spaces within cities can still be impacted by city pollution due to their proximity to pollution sources like vehicles and construction.

    Cooking at home

    Actions like frying food in the kitchen increased PM2.5 levels by five times. The combustion process while cooking releases particulates into the air, likely contributing to this increase.
