Frequently asked questions
- Which measurements matter most indoors?
- Particulate matter and carbon dioxide are commonly tracked indoors, alongside humidity and temperature. The most useful mix depends on what you want to understand about your space.
- How do I use the readings?
- Readings help you spot trends, such as rising carbon dioxide in a closed room, so you can act by ventilating. Watching changes over time is often more useful than a single figure.
- Do these monitors need calibration?
- Some sensors self-calibrate over time, while others benefit from fresh-air exposure as described in the instructions. Following the manufacturer's guidance keeps readings meaningful.
