Understanding the importance of CO2 monitoring indoors
Why Elevated CO2 Levels Indoors Are a Concern
Many people focus on pollutants like dust or volatile organic compounds when thinking about indoor air quality, but carbon dioxide (CO2) is just as important. When CO2 accumulates in enclosed spaces, it can lead to symptoms like headaches, drowsiness, and reduced concentration. High CO2 levels are often a sign of poor ventilation, which can also allow other gases and contaminants to build up. This makes CO2 monitoring a key part of any comprehensive air quality strategy.
CO2 and Other Gases: What You Need to Know
It's easy to confuse carbon dioxide with carbon monoxide, but they are different gases with distinct health risks. Carbon monoxide is dangerous even at low concentrations and requires a dedicated monoxide detector or alarm. CO2, on the other hand, is naturally present in the air but becomes a problem when levels rise above safe thresholds, usually measured in parts per million (ppm). A quality monitor or portable detector can help you track both gases, but make sure your device is designed for the specific gas you want to measure.
Why Monitoring CO2 Is Essential for Health and Comfort
