Über drei Jahre hat @grvsmth die Luftqualität in Innenräumen gemessen und teilt dankenswerterweise die eigenen Erkenntnisse mit uns.

Die Grundlage: Wo die gemessenen CO2-Werte gering sind, ist auch die Ansteckungsgefahr mit via Aerosolen übertragenen Viren geringer.

Ein schöner Bericht über (soweit möglich) sichere und weniger sichere Orte - und gute und weniger gute Bedingungen. Trotz US-Kontext m. E. weitestgehend auf uns übertragbar.

Nine observations from carbon dioxide monitoring

Introduction In the first year of the COVID-19 pandemic I learned that we can estimate our level of risk by checking the concentration of carbon dioxide in the air, because when infected people breathe out virus aerosols, they also breathe out CO2.  I recently wrote about some limitations on this

Und wo wir beim Thema sind. 😅 Welche Geräte nutzt Ihr noch mal zur CO2-Messung unterwegs und seid Ihr damit zufrieden?

Ich hatte ja das Gerät von Airvalent. Winzig klein, passte in jede Hosentasche, allerdings hat der Akku inzwischen quasi den Geist aufgegeben. 😌 Jetzt überlege ich, ob es wieder ein Airvalent wird oder ein anderes Gerät.

@melsdung Vielen dank für das weiterleiten! I can read German with time and a dictionary, but I appreciate your patience with my posting in English!

My current model is an INKBIRD PTH-9C, bought in November 2023 and my only complaint is that the battery indicator isn't reliable. I also got a Temtop that measures both particulates and CO2 (you can see it in one of the pictures), but it doesn't have very long battery life.

Stay safe and healthy!

@grvsmth Thank YOU for your work and that article! 🧡 I always think it is good to inform people with the least barriers as possible, so I roughly summarized your text for the German-speaking and my impression is that it reached a lot of people. 😊

Also thanks for your recommendation!

Unfortunately, I just caught Covid four weeks ago for the first time. 🫩 But of course I try to not get it that soon again. Please stay safe as well! 🍀

@melsdung I'm sorry to hear that you got COVID! Despite my efforts, I have had it at least three times - but not last year or this year so far. I hope you're mostly recovered!
