What does a ventilation system provide?

A ventilation system primarily provides fresh air to indoor environments. This is essential for ensuring a healthy and comfortable atmosphere by replenishing oxygen levels and expelling stale air, which can contain pollutants and excess moisture. Adequate ventilation helps to improve indoor air quality, reducing the risk of respiratory issues and enhancing overall well-being.

While humidity control is a related aspect of indoor climate management and can be addressed through specialized systems, it is not the primary function of a standard ventilation system. Lighting and sound insulation do not fall within the responsibilities of a ventilation system, as those functions pertain to different types of building systems designed specifically for illumination and noise control, respectively. Thus, the role of a ventilation system is distinctly oriented toward providing fresh air for occupants.
