Our suggested policy actions should focus on launching national public awareness campaigns, supporting transition to cleaner cooking and air cleaning technologies, and addressing socioeconomic disparities related to high indoor air pollution.

The high indoor PM2.5 levels recorded in homes indicate an urgent need to tackle indoor air pollution as a health risk factor, particularly in deprived and minority ethnic households.

Higher PM2.5 was observed with higher deprivation levels and also scaled with the number of occupants. Occupant ethnicity, housing tenure, smoking and cooking heat source also had an impact on levels observed.

We found that homes had a mean daily average indoor PM2.5 concentration of 20.2 µg/m3, exceeded the WHO 24-hour threshold an average of 41% monitored days, and exceeded 100 µg/m3 an average of 4% monitored hours.

The paper was led by Rachael Cheung and the PM2.5 sensor data was led by Lia Chatzidiakou. This work was part of the INGENIOUS project led by Nic Carslaw @york.ac.uk

Probably just let them rippen on the shelf!

Our boiler needs replaced, was thinking of a heat pump. And now we have to wait and see what she does.... I realise we are those pesky middle class folks benefitting but agree its short sighted

Seems appropriate
