CO2 monitor showing a reading of 0837ppm

Banshee Labyrinth basement - not at all bad. But worth considering supplementing with a HEPA air filtration unit or two. Just one reading so far of 837ppm , so a provisional #CO2Review ⭐⭐⭐3 stars, but not far off 4 stars.

Venue 17: Assembly Studio 3, George Square scored top marks 👏. Two readings done at two shows, three under 600 and one under 800ppm (lowest & highest shown), and confirmed by another. Our reviewer said the shows were good too! #CO2Review ⭐⭐⭐⭐⭐ 5 stars

More CO2 Reviews from @edfringe.bsky.social @edintfest.bsky.social, mostly good, but the Spiegel tent at 1026ppm was an exception. According to our reviewer "Sold out. Not good ventilation. Man coughing behind us.". #AirAware #CO2Review ⭐ ⭐ 2 stars . Would be good to confirm with more readings.

Good CO2 reading 683, event sold out, an hour in. Sat lower down.

Still ok CO2 reading, not sold out, sat lower down.

But evening reading not good, same day as the 803 reading, now at 1131. Sat higher up.

More people are taking CO2 readings at Edinburgh festival venues! Varied, if generally good, readings
@edfuturesinstitute.bsky.social. Factors seem to include where sat. Higher up=worse. Maybe to do with ventilation airflow? #CO2Review Futures Institute: a cautious⭐️⭐️⭐️⭐️4 stars
