an update on the heating situation

it is 30C at my desk at work (with the AC running). Air quality outside (using Haidian Wanliu reading from aqicn.org) is 76, indoor air quality monitor is showing between 15-20 micrograms / cubic meter.

Pictured above is my new monitoring device. This picture was actually taken last Friday when all of a sudden, a cold front (or wind front) moved into Beijing and completely dispersed the previously 350+ AQI situation, dramatically improving the outdoor air quality. The window was open when I took that photo (and it was still 28C!).

I've been using that nifty little sensor on my desk to get an understanding of what the air quality is like inside the office. My conclusions so far? On days where AQI is 350+, the indoor air quality in the office is "hazardous" by international standards (in the 200s). The air quality in my apartment, if I aggressively treat the air with all my air filters, can be as low as 50-70 when it is 400+ outside.

At this point, I am planning on frequently requesting to work from home whenever the air quality outside reaches a certain point. Hopefully I don't have to do it that frequently. But we shall see. Beijing is a place that frequently exceeds  imagination.
