Energy recovery ventilator (ERV) cores add fresh air to homes while minimizing energy loss. The core is where the transfer of energy takes place, using inside air to heat or cool the outside air entering the unit. This results in less energy use, and faster heating and cooling. An ERV also transfers moisture, so inside air is always comfortable - this reduces the need for extra, costly moisture-control products.
This easy-to-install core simply slides into place.
