Why Ventilation So Important?

Proper ventilation keeps the air fresh and healthy indoors. Like the lungs, homes need to be able to breathe to make sure that fresh air comes in and dirty air goes out. Air indoors can build up high levels of moisture, odors, gases, dust, and other air pollutants.To provide good air quality, enough air needs to be brought in and circulated so that it reaches all areas of the home. For almost all homes, windows and structural elements contribute to bringing in fresh air.

1. Exhaust ventilation systems work by depressurizing the building and are simple and inexpensive to install.

2. Supply ventilation systems work by pressurizing the building, and are also relatively simple and inexpensive to install.

3. Balanced ventilation systems, if properly designed and installed, neither pressurize nor depressurize a house. Rather, they introduce and exhaust approximately equal quantities of fresh outside air and polluted inside air.

What is House Ventilation?

The decision to use house ventilation is typically motivated by concerns that natural ventilation won’t provide adequate air quality, even with source control by spot ventilation. Whole-house ventilation systems provide controlled, uniform ventilation throughout a house. These systems use one or more fans and duct systems to exhaust stale air and/or supply fresh air to the house.
