Your indoor air, always within reach.
Indoor air is not something you can judge by feel. ArimAir indoor monitors measure six air quality parameters at once — including radon, VOCs and carbon dioxide, which once required professional equipment — and the app shows every reading with guidance for each risk level. We spend around 90% of our day indoors.
- 01
Live readings
Check pollutant levels around the clock — in the app wherever you are, or on the front display of models that have one.
- 02
Alerts you set
When a measured level rises above the threshold you set, the app sends a notification.
- 03
Live and historical records
See current readings from the space where your device is installed, along with daily, weekly and monthly history.
The app is designed to be used together with an ArimAir measurement device. For the outdoor units, OA200 and OA100, a dedicated monitoring website is the standard interface and mobile app integration is available by arrangement. iOS is listed in the official Korean product specifications; please contact us about iOS availability in your region.
