Anyone know the best CO2 monitor to measure ventilation in a room for nursery stuff?
Our toddler has brought home three different colds in two months and sitting in the nursery during naptime feels stale. Made me realize we barely open the windows in here once the heat kicks on.
I started looking into air quality stuff to see if poor airflow is making everyone groggy during the day. Seems like NDIR sensors are the way to go but prices are all over the place. I saw Aranet4 mentioned a few times on other threads. How are you guys tracking airflow in bedrooms?
