Seven day Lahore AQI log, with mask and indoor decisions
From October to February, Lahore air becomes one of the worst in the world; AQI regularly crosses 300, sometimes 600. PM2.5 particles enter your lungs and bloodstream and reduce IQ in growing children. The government cannot fix this for you in a week. You can fix the next seven days by checking AQI every morning, deciding when to mask, and deciding when to keep windows shut. This week you build that habit and prove the data.
Now try it
Seven day Lahore AQI log, with mask and indoor decisions
Stretch
Build the Corsi-Rosenthal box yourself, photograph each step, and run an experiment: take an indoor AQI reading with a borrowed sensor (or the same app on a friend's phone in the same room) before and after running the box for two hours. Record the drop.

A photograph of your seven row AQI log filled in for the week, your N95/KN95 mask, and either the closed room rule or the Corsi-Rosenthal box you set up, plus the three sentence reflection.
