Good indoor air quality is essential for concentration, well-being, and health. A key factor here is the air exchange rate—that is, how often the air in a room is completely replaced within an hour. Anyone looking to improve air quality should be aware of the air exchange rate and monitor it regularly.
Calculating Air Change Rates: Explained Simply
The air change rate can be calculated using a simple formula:
Example: An office with a volume of 50 m³, into which 100 m³ of fresh air flows per hour, has an air change rate of 0.5/h. Theoretically, therefore, the air is completely replaced twice per hour.
If you frequently work with different rooms or ventilation systems, you can also use an air change rate chart to quickly see which air change rate is recommended for different room sizes and occupancy levels.
Why fresh air is so important
Insufficient air exchange leads to increased levels of CO₂, dust, and pollutants. This can cause fatigue, headaches, and difficulty concentrating. Especially in offices, children’s rooms, or bedrooms, an adequate air exchange rate is crucial for keeping the air fresh and healthy.
How the air-Q helps ensure proper air circulation
This is where the air-Q comes in. The device measures indoor air quality in real time and indicates exactly when to ventilate in order to achieve the optimal air exchange rate. This allows you to control air quality precisely, without having to rely on guesswork.
Practical benefits of air-Q
- Real-time measurements of CO₂, particulates and other pollutants
- Indicate when the air in the room needs to be changed
- Support for healthy working, learning, and sleeping
With the air-Q, users not only know when to ventilate, but can also actively improve air quality and keep it healthy over the long term. By knowing the air exchange rate and following the air-Q’s recommendations, you can protect your health, well-being, and performance.
