Samara Geller works on a variety of toxics and chemical transparency issues, including food packaging, antimicrobials and cleaning products. She focuses on developing and expanding EWG’s healthy cleaning consumer guides and programs, including EWG VERIFIED™ Cleaning Products, helping to raise consumer awareness and influence market change. Geller manages EWG’s Guide to Healthy Cleaning, which reviews and rates more than 3,100 household products based on ingredient hazards and disclosure. She also contributes to EWG’s California policy efforts.

In 2015, Geller helped introduce much-needed cleaners disclosure legislation in the state. Most recently, she was part of a team of nonprofit organizations and industry stakeholders that negotiated to help pass the Cleaning Product Right Know Act of 2018.

“We see this as a first step toward safer formulation. Knowing what’s in a product is necessary to evaluate the exposures, evaluate the ways these chemicals are getting into our bodies, and evaluate how they’re impacting the environment.”

“To avoid ingesting or breathing dust as much as possible, wipe up dust frequently – don’t just save hard-to-reach spots for spring cleaning – and follow a ‘top-down’ strategy. Start with ceilings and high shelving, and work your way to the floors to limit redistribution of dust and other particles to freshly cleaned surfaces.”
- Samara Geller
“Some of those potential harms may be associated with cumulative exposure to small doses over time, while in other cases, including with certain endocrine disruptors such as BPA, exposure during critical windows of development may impact the growing brain or reproductive system in detrimental ways.”

“Dryer balls help to lift and aerate the clothing and shorten dryer time. The less dryer time, the less static there will be. Stick a set of four to six balls in the dryer, and even your heaviest loads will dry quickly and evenly.”

“Even if the product appears safe – i.e. is marked ‘green’ or ‘fragrance-free’ – that doesn't necessarily mean it's free of dangerous chemicals. Labeling is a massive issue with cleaning products, and their ingredients are disclosed less often.”

“Most routine cleaning does not require disinfection. Simple soap and water is enough for removing most household dirt and organic matter.”
