Best Water Filters That Remove PFAS & PFOA

Water pollution – unfortunately, it’s not just a local issue but has become a global concern with contaminants like PFAS and PFOA posing significant health risks. These nasty substances can easily find their way into our drinking water sources leaving us with major health problems including cancer, hormone disruptions, and developmental issues.

As fellow humans who want to live long and healthy lives, investing in the right tools to keep ourselves safe is crucial! And one of these tools is an effective filtration system that removes harmful substances from our water supply.

In this article, I’ll be sharing some of the best water filters for removing PFAs and many other contaminants. That will give you peace of mind knowing your family is drinking clean and safe water.

Key Takeaways:

  • Reverse osmosis systems and granular activated carbon (GAC filters are highly effective in removing PFAS and PFOA from water.
  • Solid block carbon filters and activated alumina filters are also reliable options for removing these contaminants.
  • Consider additional features like carbon pre-filters or high micron ratings for enhanced filtration efficiency.
  • Regularly maintain and replace filter cartridges as recommended by the manufacturer to ensure optimal performance.

The Importance of Removing PFAs from Drinking Water

Before diving into the top water filters, let’s understand why it’s essential to eliminate PFAS and PFOA from our drinking water. PFAS are man-made chemicals commonly used in industrial processes and consumer products. Due to their persistence in the environment, they can contaminate water sources and accumulate in our bodies over time.

Studies have associated exposure to PFAS with various health risks, including liver damage, immune system dysfunction, and certain types of cancer. Pregnant women and young children are particularly vulnerable to these chemicals’ harmful effects.

Therefore, ensuring that your drinking water is free from PFAS is crucial for maintaining good health.

How I Selected The Best Water Filters for PFAs & PFOA

When I delved into the research and testing of products for this guide, my focus was purely on water treatment systems that prioritize reducing PFAs contamination. As a health-conscious individual myself, it was important for me to find only the best of the best.

After careful consideration and evaluation, I selected filters based on their proven ability to effectively remove PFAs & PFOs, valuable input from customers who have already tried them out firsthand, practicality and affordability — all while upholding impeccable quality standards.

I wouldn’t endorse anything less than what I would personally trust in my own home. So you can always count on me to provide unbiased recommendations that are tailored just for you!

Top Water Filtration Processes for Removing PFAs & PFOA

Here are some of the best water filtration technologies available on the market that remove PFAs:

1. Reverse Osmosis (RO) Systems:

  • Reverse osmosis systems are considered highly effective in removing PFAS and PFOA from water.
  • They use a semi-permeable membrane to filter out contaminants, including these harmful chemicals.
  • Look for RO systems with additional carbon filters for enhanced removal capabilities.

2. Granular Activated Carbon (GAC) Filters:

  • GAC filters are widely used for removing organic contaminants, including PFAS and PFOA.
  • These filters contain activated carbon that adsorbs the chemicals, trapping them and preventing them from passing through.
  • Ensure that the GAC filter you choose is specifically designed to remove PFAS and PFOA.

3. Solid Block Carbon Filters:

  • Solid block carbon filters are another effective option for removing PFAs.
  • They contain a dense block of activated carbon that captures and absorbs contaminants as water passes through.
  • Look for solid block carbon filters with a high micron rating to ensure optimal filtration efficiency.

4. Activated Alumina Filters:

  • Activated alumina filters are specifically designed to target fluoride, arsenic, and other contaminants, including PFAs.
  • These filters use adsorption to trap and remove harmful chemicals from the water.

5. Ion Exchange Filters:

  • Ion exchange filters work by replacing harmful ions with harmless ions.
  • These filters can effectively remove PFAS and PFOA from water through the exchange process.

Frequently Asked Questions

What are PFAS and PFOA?

PFAS (Per- and Polyfluoroalkyl Substances) and PFOA (Perfluorooctanoic Acid) are synthetic chemicals widely used in various consumer products. They are harmful and persistent pollutants that can contaminate water sources and pose health risks when ingested.

How can I determine if my water contains PFAS and PFOA?

Testing your water is the most reliable method to determine the presence of PFAS and PFOA. Contact your local water utility or consider using home water testing kits. You can also send samples to certified laboratories for comprehensive analysis.

Do all water filters remove PFAS and PFOA?

No, not all water filters are capable of removing PFAS and PFOA. Standard pitcher filters, faucet-mounted filters, and basic carbon filters may not be sufficient. It’s important to choose filters explicitly designed and tested for PFAS/PFOA removal.

Can boiling water remove PFAS and PFOA?

Boiling water does not effectively remove PFAS and PFOA. These contaminants are resistant to high temperatures and require specialized filtration methods, such as activated carbon or reverse osmosis, for effective removal.

Is it necessary to filter all the water in my house to remove PFAS and PFOA?

Filtering all the water in your house is not always necessary. Targeting the removal of PFAS and PFOA from your drinking water is usually the primary concern. However, if your water source is heavily contaminated or you want to ensure all water uses are covered, you may consider whole-house water filtration systems that specifically target PFAS and PFOA removal.

Are there any certifications I should look for when choosing a water filter for PFAS removal?

Yes, it’s important to look for water filters that have been tested and certified by independent third-party organizations, such as NSF International or Underwriters Laboratories (UL), for their effectiveness in removing PFAS and PFOA. The certifications to look for include NSF/ANSI 53 or NSF/ANSI P473, specifically for PFAS removal.

Can I use a water softener to remove PFAS and PFOA from water?

Water softeners primarily target mineral hardness in water, such as calcium and magnesium, and are not designed to remove PFAS and PFOA. These contaminants require specific filtration methods like activated carbon or reverse osmosis for effective removal.
