Are whole house ventilation systems worth it?
Ventilation is important because without it, the air in your house would become stale, damp and generally unpleasant. Adequate ventilation ensures that the air inside your home changes frequently enough to avoid it getting stale.

How do I add fresh air to my house?

How many air vents should a house have?
Generally, the size of your home determines how many vents you will need per room. If your room is larger than 100 square feet, you will need more than one vent (at least two) to really get adequate airflow to the room. If the room is smaller, you only need one.
What are the disadvantages of natural ventilation?
Another disadvantage of natural ventilation is that it is restricted in the extent to which it can supply cooling in hot climates and especially ones that are also moist. For this system to be allowable in some climates, it is necessary to join it with some form of tolerable (low-energy) cooling system.
How does a whole house ventilation system work?
Exhaust ventilation systems work by depressurizing the building. By reducing the inside air pressure below the outdoor air pressure, they extract indoor air from a house while make- up air infiltrates through leaks in the building shell and through intentional, passive vents.
When should a whole house vent be used?
Some experts recommend that whole-house ventilation systems be controlled to provide fresh air only when occupants are home to minimize costs. If the occupants and their activities are the principal cause of indoor air pollution, occupancy-based ventilation controls can be most effective.

Does every return vent need a filter?

How often should you ventilate your house?
If the air outside is warmer than your thermostat setting, you’re raising your indoor temperature, making your AC work harder to cool your home. So how often should you open your windows? It’s recommended that you do so once a day, for at least five minutes. Fifteen to 20 minutes is preferable.
When should I turn off my whole-house ventilation?
