While our outdoor air is polluted and sometimes unhealthy for our pets and children, indoor air quality can often be worse. Many of the products used in our furniture and other household items contain small amounts of volatile organic compounds (VOCs), which are released into our indoor air. Dust and dirt also float around inside, contributing to poor air quality. However, there are several simple things you can do to improve your home’s air quality, such as growing houseplants, changing out the HVAC air filter regularly, or installing an air cleaner.
