This one surprised me. I was cooking some Japanese curry and watched the AQI rise quickly in my livingroom and bedroom. I forgot to close the sliding door between the kitchen and livingroom. The cooking gas was probably the real culprit. I saw readings as high as 205 and 156 in two different restaurants when I was in Saigon last week.
My two air purifiers are puffing away trying to clean my rooms.
