The Great Indoors: Keeping Your Home Free of Toxics

Did you know invisible pollutants in our indoor air can be harmful to our health? In this virtual town hall, we will learn from experts the Dos and Don’ts of creating a healthy home and how we can stem the tide of unnecessary industry-created chemicals that find their way into our homes. For 26 years, CEH’s Built Environment program has worked to clean up the furniture and flooring product categories by partnering with large institutions to leverage their purchasing power and transform markets away from toxic materials and towards health-protective practices.  On November 16th at 12pm PT/3pm ET, CEH will host a virtual town hall featuring a panel comprised of four leaders in the non-toxic living field.
