The reason for this is because the air refreshes instantly after X amount of time, the gauge doesn't seem to fill slowly, but just drops to 0% CO when you're fine again. This is why you'll only ever see the 75% or 50% messages then when you look it's 0%. It's because you got the message as it was passing 75% and before it was able to put another report you were full due to insta fill.
