What is the main reason for ventilating a home?

Ventilating a home primarily serves to replenish oxygen and create a healthy environment. Proper ventilation is essential for maintaining indoor air quality, as it helps to remove stale air, pollutants, and excess moisture that can accumulate within living spaces. This process not only ensures a fresh and breathable atmosphere but also contributes to preventing issues such as mold growth and other health hazards associated with poor air quality.

Additionally, adequate ventilation allows for a consistent supply of fresh outdoor air, which is vital for supporting the health of occupants. This is particularly important in tightly sealed homes, where the natural airflow may be limited. By ensuring a steady exchange of air, ventilation plays a crucial role in promoting overall well-being within the home.
