Hi! In our tech startup, we noticed fatigue spikes around 11 am. We installed the indoor air quality monitor for workplace in the main area. Immediately, we saw CO2 levels rising when the room got crowded. People started opening windows and adjusting AC settings naturally. The change was subtle but noticeable—fewer headaches, more alert team members, and even better moods. It’s simple, visual, and creates awareness without nagging. Over time, it helped us schedule meetings in fresher spaces and improved overall comfort and focus.
