Indoor air quality is an important consideration for offices, schools, commercial buildings, and industrial facilities. Poor ventilation, indoor pollutants, changing occupancy levels, and unsuitable temperature or humidity conditions can affect the indoor environment. For building owners and facility managers, choosing the right air quality monitoring solution is a practical step towards understanding these conditions and making informed decisions. However, not every building needs the same monitoring system. The right solution depends on the type of building, the pollutants that need to be measured, the existing ventilation system, and how the collected data will be used.
