Importance of carbon dioxide monitoring

Most people spend over 80% of their time indoors—in offices, classrooms, shops, and homes. While we often focus on temperature or humidity, carbon dioxide (CO₂) levels are one of the most overlooked yet critical indicators of indoor air quality (IAQ).

CO₂ is a natural byproduct of human respiration. It is not toxic at low concentrations, but in poorly ventilated spaces, it can quickly accumulate to harmful levels. High indoor CO₂ levels reduce oxygen availability and can lead to the following symptoms:
- Reduced concentration and cognitive performance
- Headaches, fatigue, and drowsiness
- Poor ventilation and a sense of stuffiness

What is the Safe CO₂ Level?

Many countries have introduced recommended upper limits for indoor CO₂ concentration to protect public health:
- France: 800 ppm
- Belgium: 900 ppm
- Denmark, South Korea, Japan: 1000 ppm


Once the CO₂ level exceeds these thresholds, the environment is no longer considered healthy, especially in crowded spaces.

What Should You Do When CO₂ Levels Are Too High?

To improve indoor air quality and bring CO₂ levels back to a safe range, take the following actions:
- Increase ventilation by opening windows and doors
- Activate mechanical ventilation or an air exchange system
- Reduce the number of occupants in the space
- Continuously monitor air quality using a reliable CO₂ detector

Our CO₂ Monitor: Designed for Healthier Indoor Spaces

As a professional manufacturer of indoor air quality instruments, we offer advanced CO₂ monitoring solutions to help you maintain a safe breathing environment. Our monitor features:

- Real-time CO₂ concentration tracking, with visual and audible alerts when levels exceed limits
- High-accuracy sensors, equipped with intelligent calibration algorithms
- Large display and optional app connectivity, for easy access to air quality data
- Low power consumption with long battery life, ideal for offices, classrooms, public buildings, and homes.

Our devices comply with current international IAQ standards and support proactive air management in high-occupancy environments.

Global Support for Stricter IAQ Standards

In 2024, an independent scientific community published a paper titled "Mandatory Indoor Air Quality in Public Buildings", calling for governments to adopt strict IAQ policies and enforce CO₂ monitoring in public spaces.

This initiative highlights a growing global trend: managing indoor air is not just a comfort issue—it is a public health priority.

Start Monitoring, Start Breathing Better

Whether you are a school administrator, business owner, facility manager, or health-conscious homeowner, CO₂ monitoring should be part of your daily routine.
