Why Ventilation Monitoring Matters
High CO₂ levels lead to fatigue, headaches, and poor focus — and most homes suffer from it daily. Smart monitors notify you before it becomes a problem, especially in bedrooms, offices, and basements.
Where to Use These Devices
Ideal for bedrooms, nurseries, home offices, gyms, and basements. Some models also work with HVAC or window automation to optimize airflow automatically.
