Having already taped most of my home windows shut, I’ve now began on the air-con vents. The intention is easy – to shut off each entry level via which the poisonous outdoors air leaks into our Beijing residence.

Even our double-glazing would not maintain out the smog. Probably the most harmful constituent, particulate matter smaller than 2.5 microns in diameter – or PM2.5 because it’s identified – finds a means via the tiniest of gaps the place the home windows shut.

Once I first arrived in China, 5 years in the past, there was no means of monitoring the standard of air in our residence. Like everybody else, we left it to blind religion that our air purifiers had been doing the trick.

It now transpires they weren’t. Even now on extremely polluted days, we wrestle to get our PM2.5 depend a lot beneath 25 micrograms per cubic meter, the World Well being Group’s most customary for secure air.

And that is with a number of purifiers operating at full tilt, giant box-like machines that sit within the nook of each room – two in some – the mixed noise output of which is akin to dwelling within the engine room of an plane provider.
