Preferred™ Large, Horizontal Energy Recovery Ventilator ERVCRLHB

This model ventilator may be the best choice if you have a larger home and live in a hot, humid summer climate. Use it year round. Its special, enthalpic transfer media core will help infuse indoor heating or cooling energy into the incoming air so you can have a fresh indoor environment even on extreme days. It’s a much better fresh air solution than opening a window and letting your energy dollars fly out.
