Passive House - Heat Recovery Ventilator in a Passive Home

All air coming into the house is filtered through a Merv 13 air filter. This means all of the air in the home is clean - free of pollens and particulates. All of the stale air from the home is exhausted through the other side of the HRV. With this system, all the air in the house is exchanged 9 times a day with fresh air. The best thing of all is that this system runs on 16 watts! The whole house is heated with less energy than a hair dryer.
