🌿 Monitor your indoor air quality with confidence using the Aranet4 Home Wireless CO₂ Monitor. Designed for homes, offices, classrooms and workspaces, it accurately measures carbon dioxide (CO₂), temperature and relative humidity while providing instant visual alerts when ventilation is needed.
The Aranet4 Home Wireless CO₂ Monitor helps you maintain a healthier indoor environment by continuously monitoring carbon dioxide (CO₂) levels, temperature and relative humidity. High CO₂ concentrations can reduce concentration, increase tiredness and indicate poor ventilation.

Using a high-precision NDIR (Non-Dispersive Infrared) sensor, the Aranet4 provides reliable CO₂ measurements from 0 to 9999 ppm. The colour-coded display makes it easy to understand your indoor air quality at a glance.
🟢 Green – Good air quality
