What is the primary purpose of ventilation systems like HRVs and ERVs?

The primary purpose of ventilation systems such as Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) is to ensure proper indoor air quality. These systems play a crucial role in exchanging stale indoor air with fresh outdoor air while minimizing energy loss. By facilitating this exchange, HRVs and ERVs help to control humidity levels, reduce allergens, and eliminate indoor pollutants that can accumulate in sealed environments.

In homes that are well-insulated and tightly sealed to enhance energy efficiency, the lack of ventilation can lead to air quality issues, making systems like HRVs and ERVs essential for maintaining a healthy living space. This focus on air quality aligns with building codes and standards that emphasize ventilation as a key factor in creating a conducive indoor environment.
