Monitoring CO2 is smart

Tired and can’t concentrate?

Ever feel tired and drowsy in a room? Can’t focus and head feels heavy? Your air quality might be to blame. Namely, the CO2 level.

What does Aranet4 measure?

High CO2 levels decrease productivity

According to Harvard research, high CO2 levels can decrease your productivity, cognitive abilities and general wellbeing. For example, if the CO2 concentration in the room exceeds 1000 parts per million, your cognitive function decreases by 15%. Worse yet, if CO2 levels reach 1400 ppm, your cognitive abilities drop by a staggering 50%.

CO2 level as a proxy for infection risk

Monitoring CO2 in a public space helps to prevent COVID-19 spread. CO2 is a gas produced when we exhale so the higher CO2 in the room, the more you’re breathing the air that someone else has already exhaled. Monitoring CO2 level can therefore help to minimize COVID-19 infection risk by warning you when the air quality deteriorates.
