No problems outdoors but my worry there is that being inside can easily more than double CO2. Even with a window cracked slightly. So we're ok if we have really good ventilation. A fan makes us safe. At <300PPM we would have had far less to worry about here. As CO2 reaches over 500PPM (this is not that far away) that doubling of CO2 levels from being indoors puts us in the cognitive impairment range. Not good.
