Indoor Air 2026: K Kuga CO2 is reliable metric when the concern is ventilation and/or rebreathed fraction. For disease transmission CO2 is relevant for small droplet transmission, but not necessarily for large droplets (> 5 microns). Not a great tool for short range infection risk.

Indoor Air 2026: Mark Mendell (Part 2) Peak observed CO2 is often used to indicate ventilation. Often incorrectly, especially -if steady state is not reached. -if occupancy or activities vary (single number for all spaces is incorrect). Need simple mass balance approach (Persily 2022 paper)
