STOP RE-BREATHING AIR

High CO2 levels don't just feel stuffy—they harm your health and productivity. 

High CO2 means re-breathing air and viruses that have already been in someone else's lungs, increasing potential for infection. Additionally, studies from Harvard and CU Boulder show that CO2 levels of just 1,400–1,500 ppm (common indoors) can reduce high-level cognitive function by 50%.

The Aranet4 HOME is the industry-leading portable monitor that keeps an eye on your air so you don’t have to.

  • Take Control of the Air you Breathe: Detect unsafe indoor air so you can open a window or door, or alert staff
  • Beat the Brain Fog: Stop the afternoon cognitive drop in offices and classrooms
  • Optimize Your Sleep: Catch overnight CO2 buildup in the bedroom to wake up feeling refreshed
  • Easy to Read: View real-time CO2, temperature, humidity, and pressure on a large, crisp E-ink display. Includes free re-breathed air sticker.
