- Exhaust Only – This type of system uses a small exhaust fan that is commonly placed in a kitchen or bathroom. The fan is programmed to run either continuously or intermittently to extract stale air and moisture. These systems are low cost and quite easy to install.
- Supply Only – A supply-only system includes a fan that brings fresh air into the home. The air escapes through the natural air leaks in your home. A filter can be added to trap pollen and other outdoor air pollutants before they enter the home. A dehumidifier can be added inside the home to control humidity levels.
- Balanced – A balanced system includes both exhaust and supply, controlling ventilation at both ends. This system includes separate fans to manage air supply and air exhaust. Overall, this is a better ventilation system because it provides qualities of both exhaust-only and supply-only systems, however it may be more costly to run.
