Maintaining a healthy interior atmosphere provides long-term benefits. Since a healthy environment reduces health issues, it can improve quality of life and lower healthcare expenses. Advanced and efficient heating and air-conditioning systems save energy, making them healthy, environmentally friendly, and economically sensible. These systems optimise energy use and reduce waste, answering the call for sustainable living and personal and environmental responsibility. Reduced medical expenses and energy efficiency can save money over time. Thus, people and organisations should invest in indoor air quality.
