Air quality is improving in Beijing this winter – and that’s bad news for some home appliance retailers
Stores are struggling to sell one kind of white good that previously flew off shop shelves

Just last winter air purifiers sold themselves in the smog-choked Chinese capital but fast-forward a year and sales of the home appliances have slowed to a trickle as air quality has improved in Beijing, Chinese media reported on Monday.
A combination of favourable weather and tighter pollution controls resulted in Beijing reporting its best winter air quality in five years last month.
The city had a run of 25 days when its air quality was rated “excellent” or “good”.
According to Beijing’s environmental protection bureau, air quality was at least good on 226 days – or more than 60 per cent of the time – in 2017, 28 days more than a year earlier.
The average level of PM2.5 – fine suspended particles particularly dangerous to human health – also fell by roughly 20.5 per cent from the previous year to 58 micrograms per cubic metre.
