Well, I knew it was bound to happen. After a relatively clean two months in Shanghai, the air is getting worse. Today was the first time I saw the air quality worse in Shanghai than in Saigon.

What surprised me was to actually watch the air quality get worse in my apartment even with two air purifiers going.

I turned on a third air purifier just now. This was not expected but at least my BlueAir can be turned higher to clean the whole apartment if necessary.
Tomorrow I may wear my PM 2.5 Totobo mask for the first time.

Winter is coming which means more pollution.
