PFAS are organic compounds that do not occur naturally but are found in a variety of products and even in human blood. These pervasive, persistent, “forever” chemicals have been linked to cancer and other diseases.

Cleaning products that may contain PFAS include glass cleaners, fabric and upholstery treatments, floor finishes, aerosols, and air fresheners.

“The strong carbon-fluorine bonds of PFAS make … them resistant to degradation and thus highly persistent in the environment. Some …  have been used for decades in a wide variety of consumer and industrial products … Some … have been detected in wildlife… and can accumulate in humans and remain in the human body for long periods of time (e.g., months to years). Because of the widespread use of PFAS in commerce and their tendency to persist in the environment, most people in the United States have been exposed to PFAS” — EPA

The Environmental Working Group provides useful information on avoiding PFAS, as does the Consumer Notice (CN) website. The CN website also lists manufacturer-settled class-action lawsuits and other litigation.
