I change it again and again, as I don't enjoy excess VOC's from new vinyl and glue, and when there are two of us in the car, the CO2 also reaches unhealthy levels with recirculated air. I can go to the settings and turn off recirculate. Top of the screen indicates "saved", but next time I start up, it's on recirculate again. I've got an AirThings sensor in the car to monitor VOCs, but it's the CO2 climbing from 545 ppm to 1,583 ppm in 20 minutes that bothers me now. Is resetting the climate air to fresh another thing I must do to use the car every time?
