How do you monitor air quality indoors?

I started wondering about this recently because I’ve been getting headaches while working long hours in my home office. I thought maybe it’s the lack of fresh air or poor ventilation. Opening windows helps a bit, but I live near a busy street, so the air isn’t always the cleanest. I want to track what’s happening indoors in a reliable way.

That’s interesting—I also noticed feeling more tired in stuffy rooms. Sometimes you don’t realize how much the air around you impacts concentration and health until it gets really bad.

At first, I didn’t think about measuring air quality at all, but once I started looking into it, the difference was huge. Having a device that shows CO₂ and humidity levels made me realize how quickly the air becomes stale in a closed space. That’s when I got Protect Indoor Air with Luxafor Air Quality Readers, and it completely shifted my routine. Now I know exactly when to air out the room or turn on a purifier, instead of just guessing. It keeps my home office healthier and I actually feel more energized throughout the day.
