I was just joking about this today. For years I have heard all kinds of dismissive attitude to this concept yet the last few months tech Twitter has been full of people buying really expensive CO2 meters, presumably because they were unaware of CO2 in rooms?
When you buy a Window here, or you rent a flat it usually comes with a manual that asks you to ventilate regularly and how.
If you ventilate properly, a CO2 meter is entirely pointless. CO2 levels are very predictable and you can also usually tell when the air quality drops through your senses.
- flemhans 3y agoI can't feel 2000 PPM through my senses. But at 4000 it starts getting stuffy.
- the_mitsuhiko 3y agoI really find this hard to believe. 2000 is already at the higher threshold of where people report bad air quality and drowsiness. In practical terms it doesn't matter much because if you are ventilating properly, your CO2 levels don't stay elevated for long and you really do not need to measure or observe.
- Zetobal 3y ago4000 is a badly ventilated bedroom and 5000 is the limit for sustained working. If you get nauseous at 2000 you are highly sensible.
- the_mitsuhiko 3y agoWe have a CO2 level at home, so I can validate my personal observations and those of others. But I don't even need to go to personal anecdotes, everything you can read on CO2 levels indicates that people notice.
- Zetobal 3y agoNotice is highly different from getting nauseous.
- the_mitsuhiko 3y agoNot sure where you are getting nausea from.
- Smaug123 3y ago> you can also usually tell when the air quality drops through your senses Only when you're paying attention. If I'm not paying attention, I end up in a sufficiently depressed state that I can't notice, which is extremely self-perpetuating.
- the_mitsuhiko 3y agoIf you are ventilating regularly your CO2 levels are not raising to ridiculous levels in the first place. I'm pretty sure for most people the novelty of the CO2 measurement device wears of quickly.
