Why Good Air Is More Than Just a Comfort Factor
CO₂is often associated with climate protection and greenhouse gases. Indoors, however, carbon dioxide has an entirely different significance. It serves as an indicator of how well a room is ventilated and how many exhaled substances have already accumulated in the indoor air.
When CO₂ levels rise in a room, many people report feeling tired, having trouble concentrating, or experiencing a decline in performance. Especially in offices, schools, conference rooms, and home offices, air quality can have a significant impact on productivity and well-being.
What exactly is CO₂?
Carbon dioxide (CO₂) is produced, among other things, by human respiration. While outdoor air typically contains about 400 to 450 ppm of CO₂, significantly higher levels can occur in poorly ventilated indoor spaces.
Even just a few people in a closed room are enough to cause the concentration to rise within a short time.
Typical CO₂ levels:
- Outdoor air: approx. 400 to 450 ppm
- Well-ventilated indoor spaces: below 800 ppm
- Common levels in offices and classrooms: 1,000 to 2,000 ppm
- Poorly ventilated rooms: over 2,000 ppm
How does CO₂ affect cognitive performance?
CO₂ itself is not immediately harmful to health at the concentrations typically found in buildings. However, numerous studies show that rising CO₂ levels may be associated with a decline in mental performance.
The following are particularly affected:
- Ability to concentrate
- Decision-Making
- Attention
- Reaction rate
- Problem-Solving Skills
Researchers have observed that performance on complex cognitive tasks can decline even at moderately elevated CO₂ concentrations. The exact causes are still being investigated. It is likely that several factors are at play, including poorer overall air quality and the accumulation of other exhaled substances in the room.
Why High CO₂ Levels Often Indicate a Larger Problem
CO₂ is not just a measured value, but an important indicator of air exchange.
When CO₂ concentrations rise, this often also means:
- Less fresh air supply
- Higher concentrations of odor-causing substances
- More Aerosols in the Indoor Air
- Increase in Other Airborne Pollutants
That is why CO₂ is considered one of the most important parameters for assessing indoor air quality.
Impact in the Office and When Working from Home
In modern buildings, energy efficiency is often a priority. Well-insulated buildings reduce heat loss, but at the same time can limit natural air exchange.
The result:
- Difficulty concentrating during long periods of work
- Afternoon fatigue
- Lower productivity
- Impaired spatial perception
Especially when working from home, people often underestimate how quickly air quality can deteriorate in small rooms.
How the air-Q Can Help
Personal perception is often not enough to recognize the effects of poor air quality. People adapt surprisingly quickly to rising CO₂ levels and often do not notice the deterioration until their concentration and well-being have already declined.
The air-Q continuously monitors air quality and measures, among other things:
The measured values are displayed in real time and can be analyzed via the app, web dashboard, or API.
This makes it possible to detect the following at an early stage:
- When to Ventilate
- Which rooms are chronically poorly ventilated
- How Air Quality Affects Working or Learning Conditions
The air-Q enables data-driven optimization of indoor air quality, particularly in offices, schools, conference rooms, and home offices.
Why CO₂ Measurements Are Useful
Many people rely on their instincts when it comes to air quality. The problem is that poor air quality is often not noticed until the concentration has already risen significantly.
Continuous measurement therefore offers several advantages:
- Objective Assessment of Indoor Air Quality
- Support for demand-responsive ventilation
- Improving Comfort and Well-Being
- Transparency regarding the actual conditions in the room
Conclusion
Indoor air quality affects far more than just comfort. Numerous studies suggest that rising CO₂ concentrations may be linked to reduced cognitive performance.
Anyone who wants to create productive work and learning environments should therefore not only consider temperature and lighting, but also keep an eye on air quality.
An air quality monitor like the air-Q can continuously measure CO₂ levels and other relevant air quality parameters. This makes it clear when action is needed and how indoor air quality can be improved over the long term.
