Dilution Whole-House Ventilation = Fresh Air System

Image(s)

Technical Description

Researchers estimate that people spend up to 90% of their time indoors. Homes need some means to bring in fresh air and remove stale air on a regular basis to keep the indoor air healthy, especially in today’s more airtight homes. Most state codes use ASHRAE 62.2 as their residential ventilation standard. There are different methods for meeting this standard including supply-only ventilation, exhaust-only ventilation, and balanced air ventilation.

Sales Message

Fresh air systems help ensure adequate dilution of any indoor contaminants. What this means to you is your home is supplied with enough fresh air every day so your family can breathe better. Wouldn’t you agree protecting health is too important to ignore in new homes?
