   Sub-500 CO2 at the movie theatre!!

   420 is the current outside air level. Sub-800 is relatively safe. Sub-500 is *incredible* air quality.

     It's perfectly safe, you just get a little dumb from sick building syndrome 😬

     without a fan the co2 ppm measurements are probably inaccurate as you need air movement for the optical sensor

     @yosh my airvisual pro stopped measuring pm2.5 concentrations a couple of years ago (internal fan doesn’t spin, or something), but the co2 sensor is still fine. with the bedroom windows and doors closed at night for 12 hours, the co2 level climbs to over 1200 by the morning.

     i don’t have a choice here – my pm2.5 levels stay over 200 for several weeks on end in the winter months. i have a good air purifier, but it doesn’t do anything for co2.

     This was the big Cinemaxx in Copenhagen. The lobby isn’t great (1200 PPM spike). But the actual cinema itself was *great*!

     The peak at the end was when the movie was over and we had to go back through the lobby.
