Home Ventilating Institute


Zehnder America is proud to join the Home Ventilating Institute and to earn industry recognition for our ComfoAir 350 HRV as being the most energy efficient Heat Recovery Ventilator certified so far. With Apparent Sensible Effectiveness above 90%, Sensible Recovery Efficiency of 85%-88%, and power consumption as low as .30 watts per cfm, the ComfoAir 350 HRV has crossed the threshold to the next generation of Heat Recovery Ventilation in North America. Zehnder America will continue to test and list additional models in coming months, and we expect the results to be even better for some models.
