●If this product becomes dirty, wipe it with a dry cloth or a cloth soaked in soapy water and wrung out thoroughly. If it is heavily soiled, use rubbing alcohol.

Displays the carbon dioxide (CO₂) concentration around the product in real time. Large, easy-to-read characters allow you to instantly check the concentration.

In addition to carbon dioxide concentration, five other indicators for creating a comfortable indoor space are displayed in real time: TVOC (total volatile organic compounds), HCHO (formaldehyde), temperature, and humidity.

The large, highly visible LCD displays the carbon dioxide (CO₂) concentration using numbers and color, so you can immediately see the level of caution and when to ventilate.

When the carbon dioxide (CO₂) concentration is up to 600 ppm, the display will show "GOOD" in green, between 600 ppm and 1000 ppm in yellow "OK," and above 1000 ppm in red "POOR." When the red "POOR" light is on, ventilation is required, so please ventilate the room. To prevent sick building syndrome, such as itchy eyes, runny nose, dry throat, and nausea, check the TVOC (total volatile organic compounds) and HCHO (formaldehyde) levels.
