Whole House & Local Ventilation Systems: How They Affect The Air You Breathe


Ventilation is a necessary component of any home, especially with how many functions modern HVAC systems have. A good ventilation system will keep the

inside environment ventilated, heated, cooled and humidified depending on the homeowners preference.

Whole-house ventilation systems, in particular, can affect indoor air quality on a larger scale than local ventilation systems, which may not be as advantageous for a larger living space.

How Whole-House Ventilation Helps:

Whole-house ventilation systems use one or several duct systems and linked fans to get rid of stale air and supply the home with fresh air. All of the air cycled through the home is processed through filters that are designed to pick up unwanted contaminants and prevent them from cycling around.

Whole house ventilation is advantageous for larger buildings and structures because the entire system functions to keep indoor air desirable in every room of the home. Separate duct zoning systems may require special filter care, but ultimately these systems are ideal for use with larger environments, especially ones that need to be maintained at different comfort levels depending on use.

Using Local Ventilation Systems:

Local ventilation systems, on the other hand, affect indoor air quality on a smaller scale. These are often limited to a single room or set spaces, which makes them much more affordable and easier to install and maintain.

However, because of the smaller area affected by these installations, they are not ideal for larger environments unless they are installed in each individual room. Local ventilation systems are ideal for smaller spaces such as studio apartments, as they can provide individuals with better indoor air quality for their special needs.
