A cost-effective monitor for use in schools, restaurants, and other small-to-medium sized buildings that alerts users when conditions are present that may increase the risk of exposure to airborne viral transmission.

Classrooms, restaurants, and buildings with outdated HVAC and ventilation systems can foster environments where the risk of airborne virus transmission could increase. Honeywell proprietary technology that monitors CO2 levels, coupled with user-controlled settings to account for human activity levels in an indoor area, provides users with a portable, cost- effective, and user-friendly solution that alerts when conditions are present that may increase the risk of exposure to airborne viral transmission.
