What is crucial for maintaining proper ventilation in indoor spaces?

Regularly changing air filters and cleaning ducts is crucial for maintaining proper ventilation in indoor spaces because it ensures that the air circulation system is functioning efficiently. Air filters trap dust, allergens, and other particles that can build up over time; if they are not changed regularly, they can become clogged, reducing airflow and the system's overall effectiveness. Similarly, clean ducts prevent blockages and ensure that air can flow freely throughout the space.

Effective ventilation helps to maintain a healthy indoor environment by removing stale air, reducing humidity, and providing a constant supply of fresh air. This is essential for the comfort and health of occupants, as it minimizes the risk of respiratory issues and unpleasant odours. Therefore, regular maintenance of air filters and ducts directly supports optimal air quality and comfort levels in enclosed spaces.
