Today the sun is shining, the birds are chirping outside the window, and the air is filled with the scent of spring. On such a fresh morning, the CO2 sensor in our house shows that the indoor CO₂ concentration is about 430 ppm.
This is a very desirable level. Generally speaking, an environment below 500 ppm makes people feel refreshed and clear-headed. Compared to the other day, when the windows were closed and the concentration reached 800+ ppm, today is really a day to feel ‘free to breathe’.
🌿 Summary:
- 🌬️ CO₂ low → fresher, more focused
- 🚪 proper ventilation → greatly improved air quality
- 🛠️ A good CO₂ sensor → good for the home environment
