I'm studying abroad in Beijing right now, and my throat began to hurt even at lower levels of PM2.5 simply because I wasn't wearing a mask. I'm very surprised at the number of people who don't wear a mask; they either don't value their health or don't know how bad the air is because they've been accustomed to it.
- im2w1l 11y agoHow much does your mask help?
- andrezsanchez 11y agoThe package says it blocks >=90%, which is still horrible for my health, but thankfully I'm leaving in less than 2 months. It certainly feels better though.
- kruczek 11y agoOut of curiosity - what are typical levels of PM2.5 over there?
- tellarin 11y ago130 - 170 AQI is kind of typical. With <50 levels sprinkled throughout the year. A couple dozen days a year it gets really bad, worse than this current streak.
- andrezsanchez 11y agoI didn't even look at the levels when I came in September because everything looked fine, but lately it's varied a lot, between 100-350 the past few weeks.
