PFAS stands for per- and polyfluoroalkyl substances. They are a large group of man-made chemicals that have been used since the 1940s in industrial processes and consumer products.

 

PFAS in drinking water — often referred to as “forever chemicals” — has become a growing concern for homeowners across the United States. Understanding what PFAS are, where they come from, how they may affect health, and how they can be reduced is an important step toward protecting your household’s water quality.

PFAS have been used in a wide range of applications, including:

• Non-stick cookware coatings

• Water- and stain-resistant fabrics

• Food packaging materials

• Firefighting foams

• Industrial manufacturing and surface coatings

 

Over time, PFAS have entered the environment through industrial discharge, landfills, wastewater systems, and firefighting training sites. Because PFAS move easily through soil and water, they can contaminate groundwater and surface water sources.

 

As a result, PFAS have been detected in municipal water systems and private wells throughout the United States.

Scientific research from public health agencies has linked long-term exposure to certain PFAS with potential health concerns. These associations are based on studies of populations with elevated or prolonged exposure.

 

Documented health concerns associated with PFAS exposure include:

• Increased cholesterol levels

• Effects on liver function

• Suppressed immune system response

• Reduced effectiveness of vaccines

• Developmental effects in infants and children

• Pregnancy-related complications

• Increased risk of certain cancers, including kidney and testicular cancer

 

One of the primary concerns with PFAS is that they can accumulate in the body over time. Even low-level exposure through daily drinking and cooking may increase overall PFAS levels in the body.

Reverse osmosis (RO) filtration is one of the most effective residential methods for reducing PFAS in drinking water.

 

Reverse osmosis systems work by forcing water through a semi-permeable membrane with extremely small pores. This membrane blocks many contaminants, including PFAS molecules, while allowing clean water to pass through.

 

Studies have shown that properly designed and maintained reverse osmosis systems can remove approximately 90–99% of PFAS, including both long-chain and short-chain compounds.

 

Because of this high level of removal, reverse osmosis is widely recognized as one of the most reliable household options for reducing PFAS exposure at the point of use.

Not all water filters are designed to address PFAS. Many basic filters are intended only to improve taste or reduce chlorine and may not significantly reduce PFAS levels.

 

When addressing PFAS, filtration effectiveness depends on proper system design, certified components, and regular maintenance. Choosing the correct filtration approach is critical to achieving consistent and meaningful PFAS reduction.
