What should be prioritized to maintain good indoor air quality when using an ERV?

To maintain good indoor air quality when using an Energy Recovery Ventilator (ERV), prioritizing regular filter changes and maintenance is crucial. ERVs work by exchanging stale indoor air with fresh outdoor air while recovering energy from the exhaust air to condition the incoming air. Over time, filters can accumulate dust, allergens, and other particulates, which can reduce their effectiveness and potentially lead to poor indoor air quality.

Regular maintenance ensures that the filters are clean, which helps in effectively capturing contaminants and minimizing allergens that may circulate within the indoor environment. Furthermore, well-maintained ERVs can operate efficiently, enhancing ventilation while reducing the burden on HVAC systems, leading to better air quality and comfort levels within the space.

In contrast, increased humidity levels can lead to mold growth and discomfort, maximizing indoor air circulation is beneficial but should not compromise air quality, and reducing overall air exchanges could limit fresh air intake, which is essential in promoting healthy indoor environments.
