Best CO2 Monitors for Office

Research consistently shows that elevated CO2 in office environments reduces cognitive performance by up to 50% at levels commonly found in meeting rooms and open-plan offices. A good CO2 monitor helps facilities managers and employees understand when a room needs more fresh air, directly improving focus and decision-making. Office monitors benefit from WiFi connectivity for remote dashboard viewing and alert capabilities that notify building managers before conditions deteriorate. The best office monitors are unobtrusive, accurate, and capable of logging data for compliance with indoor air quality standards like ASHRAE 62.1. Here are our top picks for the modern workplace.
