hour or so ago.
Having charged it I switched it on and within seconds it was reading 1450+ppm. (28°C hu idiot 30%). Cue Google, where I found recommended indoor CO² to be:
250-400ppm - Normal background concentration in outdoor ambient air
400-1,000ppm - Concentrations typical
Having charged it I switched it on and within seconds it was reading 1450+ppm. (28°C hu idiot 30%). Cue Google, where I found recommended indoor CO² to be:
250-400ppm - Normal background concentration in outdoor ambient air
400-1,000ppm - Concentrations typical
of occupied indoor spaces with good air exchange
1,000-2,000ppm - Complaints of drowsiness & poor air.
2,000-5,000ppm - Headaches, sleepiness & stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate & slight nausea may also be present.
5,000ppm =
1,000-2,000ppm - Complaints of drowsiness & poor air.
2,000-5,000ppm - Headaches, sleepiness & stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate & slight nausea may also be present.
5,000ppm =
Workplace exposure limit (as 8-hour TWA) in most jurisdictions. >40,000ppm - Exposure may lead to serious oxygen deprivation resulting in permanent brain damage, coma, even death.

Reading that I instantly got out of bed and opened 2 more windows to allow free air flow. The
readings rapidly dropped to 400ppm (yes less than 1/7 what they had been).
My next move was to get out of bed and write this thread!
Anyone this concerns, especially #Longcovid sufferers like me, PLEASE do what I did and get a cheap monitor such as https://www.amazon.co.uk/dp/B08L3S6WFF/ref=cm_sw_r_cp_apa_glt_fabc_Y02KV4P1N0XCBR6WJ3DJ?_encoding=UTF8&psc=1

I don't regret the ÂŁ12.09 (with 1 day free delivery) I spent. I am sure you won't regret what it, or similar costs you. Mine will go everywhere with me now!
Good health to you.
