What Are VOC's?

Volatile Organic Compounds (VOCs) are a large group of chemicals that are found in many products we use to build and maintain our homes. Once these chemicals are in our homes, they are released or “off-gassed” into the indoor air we breathe. It is important to know that smelling is not a good indicator of the health risks associated with VOCs as many are odorless and may or may not be able to be smelled
