The Indoor airPLUS Construction Specifications are designed to help improve indoor air quality in new homes as compared with new homes built to minimum code. However, these measures alone cannot guarantee that you won't experience indoor air quality problems, since the activities of people in your home can significantly compromise indoor air quality. For example, allowing smoking indoors will surely lead to poor indoor air quality, whether or not your home earned the Indoor airPLUS label. You should consider Indoor airPLUS as a way to reduce the likelihood of experiencing indoor air quality problems. But, remember to minimize the use of known health hazards in your home and properly maintain your home and its systems.
