Calculating Air Change Rate and Improving Room Air
The air change rate shows how often the air in a room is renewed. Good air quality protects health and concentration. The air-Q measures pollutants and CO₂ in real time and gives clear guidance on when you need to ventilate.
Healthy indoor air is crucial for concentration, well-being, and health. A key factor here is the air change rate, meaning how often the air in a room is completely replaced within an hour. Anyone wanting to specifically improve air quality should know their air change rate and check it regularly.

Calculating the air change rate: explained simply
The air change rate can be calculated using a simple formula:
Example: an office with a room volume of 50 m³, into which 100 m³ of fresh air flows per hour, has an air change rate of 0.5/h. Theoretically, the air is therefore completely renewed twice per hour.
If you often work with different rooms or ventilation devices, you can also use an air change rate table to quickly see which air change rate is recommended for different room sizes and occupancy levels.
Why air change is so important
Too low an air change rate leads to elevated CO₂, dust, and pollutants. This can cause fatigue, headaches, and concentration problems. Especially in offices, children's rooms, or bedrooms, a sufficient air change rate is crucial to keeping the air fresh and healthy.
How the air-Q helps with the right air change
This is where the air-Q comes in. The device measures room air in real time and shows exactly when you should ventilate to achieve the optimal air change rate. This lets you specifically control air quality without having to rely on guesswork.
Practical benefits of air-Q
- Real-time measurements of CO₂, particulate matter, and other pollutants
- Shows when air change is needed in the room
- Supports healthy working, learning, and sleeping
With the air-Q, users not only know when they need to ventilate, but can actively improve air quality and keep it healthy long-term. Anyone who knows their air change rate and follows the air-Q's guidance protects their health, well-being, and performance.
