147CFM recovery ventilation system

HRV ERV energy recovery ventilator energy saving hepa filter

Product Description

An energy recovery ventilator system (ERV) fits in colder climates, in the homes where there is no excess moisture in heating season, as well as for homes located in warmer climates where the outside humidity level is high.

As for the HRV system, the ERV system recovers heat; however, it also recuperates the energy trapped in moisture, which greatly improves the overall recovery efficiency.

In air conditioned homes, when it is more humid outside than inside, the ERV system limits the amount of moisture coming into your home. In humidified homes, when the humidity level is low in winter, the ERV system limits the amount of moisture expelled from your home.
