So you’ve heard there are probably forever chemicals lurking in your drinking water and now you find yourself wondering about how to remove PFAs from water to make it safe for drinking. We understand! PFAS, or per- and polyfluoroalkyl substances, have become a growing concern in drinking water across the country. Often referred to as “forever chemicals,” these compounds are incredibly resistant to breaking down in the environment, making them particularly challenging to remove from water sources and ultimately, your body. Found in everyday products like non-stick cookware, firefighting foam, and water-resistant clothing, PFAS can seep into groundwater, eventually making their way to household taps.
Exposure to PFAS is linked to serious health risks, including increased cancer risk, hormone disruption, and immune system issues. For homeowners, understanding how to remove PFAS from drinking water is essential to ensuring safe, clean water. In this article, we’ll explore effective filtration solutions you can use to combat PFAS contamination and protect your family’s health.
What Are PFAS and Why Are They Dangerous?
PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals widely used in various industries for their water- and grease-resistant properties. These chemicals can be found in everyday items like non-stick cookware, stain-resistant fabrics, food packaging, and firefighting foam. Due to their strong chemical bonds, PFAS are incredibly durable, persisting in the environment and in human bodies for long periods—hence their nickname, “forever chemicals.” Over time, these compounds can accumulate in water sources, leading to contamination of drinking water supplies.
The health risks associated with PFAS exposure are significant and well-documented. Long-term exposure to even small amounts of PFAS has been linked to a variety of serious health problems, including certain cancers, liver and kidney damage, reproductive and developmental issues, and hormone disruption. PFAS can also weaken the immune system, making individuals more vulnerable to infections and other health concerns. Because of their widespread use and persistence, PFAS pose a unique challenge for water treatment, and it’s essential for homeowners to understand how to effectively filter these contaminants from their drinking water.
How to Test for PFAS in Your Water
Testing your water for PFAS is an important first step in understanding the level of contamination and determining which filtration solutions will be most effective. While PFAS are difficult to detect without specialized equipment, there are several options available to help you gauge the presence of these chemicals.
Home Testing Kits
There are DIY test kits on the market that allow you to collect a water sample and send it to a lab for analysis. These kits are typically easy to use and provide insight into the PFAS levels in your water. However, it’s important to note that home testing kits can vary in accuracy, so it’s best to choose one from a reputable provider. These kits are particularly useful for homeowners with private wells, as these water sources are not regulated and could have higher levels of contaminants.
Professional Water Testing Services
For more precise and reliable results, consider professional water testing services. Many local water quality companies or certified laboratories offer PFAS testing, often providing a detailed report on the specific PFAS compounds present and their concentrations. Professional testing is especially recommended if you live in an area known for PFAS contamination or if you’re considering investing in a filtration system and want a thorough analysis.
Having said this, it is fairly safe to assume that if your water source is from a public water resource, then it contains PFAS. You can also check out local reports we provide on our website for your city regarding test results.
How to Remove PFAs From Water: Effective Filtration Methods
Removing PFAS from drinking water requires specialized filtration methods, as these “forever chemicals” are highly resistant to traditional water treatment. Fortunately, certain advanced filtration systems have been proven effective in reducing PFAS levels. Here are the top methods to consider:
Activated Carbon Filtration
Activated carbon filters are one of the most accessible and widely used options for reducing PFAS, especially in point-of-use systems. These filters work by adsorbing contaminants onto a porous carbon surface, trapping PFAS molecules within the filter media.
- Effectiveness: Activated carbon is particularly effective at removing longer-chain PFAS compounds. However, for optimal performance, filters must be replaced regularly, as they can become saturated and less effective over time.
Reverse Osmosis (RO)
Reverse osmosis systems are the most effective at filtering PFAS, as well as a wide range of other contaminants. RO works by forcing water through a semi-permeable membrane that blocks PFAS molecules, ensuring only purified water passes through.
- Effectiveness: RO systems can remove up to 99% of PFAS compounds, including both long- and short-chain varieties, making them one of the most reliable options for PFAS filtration.
Ion Exchange Resins
Ion exchange resins are a more advanced and specialized filtration technology designed to capture PFAS ions by replacing them with harmless ions like chloride. These resins are often combined with other filtration methods for maximum efficacy.
- Effectiveness: Ion exchange resins are particularly effective for removing both short- and long-chain PFAS compounds, which makes them useful in settings where PFAS levels are high or varied.
Choosing the Right Filtration Solution for Your Home
While there are several methods available to help you figure out how to remove PFAs from water, a reverse osmosis (RO) system stands out as the most effective choice for removal. As it reliably filters out a broad range of contaminants and achieves high levels of PFAS reduction.
Why Reverse Osmosis Is the Best Choice for PFAS Removal
Reverse osmosis systems remove up to 99% of PFAS, including both long- and short-chain varieties, which are more difficult to capture with other filtration methods like activated carbon. While activated carbon filters are affordable and widely available, they don’t always provide the same level of PFAS reduction and may require frequent replacements to remain effective.
Key Considerations When Choosing an RO System
RO systems can be installed under the sink for point-of-use filtration, providing safe water directly at your drinking and cooking source. They’re also versatile, as many models can be combined with other filters, like activated carbon, to target a wider range of impurities and enhance water taste. Although RO systems can require more maintenance and initial setup, the consistent and thorough filtration they provide makes them an ideal choice for families looking for reliable PFAS protection.
