What is one of the main benefits of using an energy recovery ventilator (ERV)?

The primary benefit of using an energy recovery ventilator (ERV) is that it effectively exchanges stale indoor air with fresh outdoor air. This process not only helps improve indoor air quality by removing pollutants, allergens, and excess humidity but also introduces fresh air, which is essential for maintaining a healthy indoor environment.

The operation of an ERV involves transferring heat and moisture between the outgoing and incoming air streams. During the cold months, the ERV retains heat from the indoor air being expelled to warm the incoming cold air, and in warm months, it can help cool the incoming warm air by transferring some of the heat to the outgoing air. This efficiency in air exchange is crucial for optimizing comfort while minimizing energy loss.

Overall, the use of an ERV significantly enhances air quality and comfort within a building, making the process of ventilation not just about airflow, but also about energy efficiency and overall environmental well-being.
