If you’re concerned about the quality of your drinking water, you’ve likely heard about PFAS (Per- and polyfluoroalkyl substances). These contaminants are linked to various health issues, and they may be lurking in your tap water.
Clearly Filtered pitchers utilize Affinity Filtration Technology, which is proven to remove up to 99.9% of PFAS chemicals from water. Independent lab tests and NSF certification further confirm their efficacy in removing harmful PFAS contaminants. Regular maintenance and filter replacement are essential for optimal performance.
This article explores PFAS in-depth, including its potential health risks, safe levels, and how Clearly Filtered products can help you remove these harmful substances from your water.

What is PFAS
PFAS are a group of synthetic chemicals that have been used in various industries since the 1940s. They are commonly found in firefighting foams, non-stick cookware, food packaging, and water-resistant fabrics. Due to their widespread use and persistence in the environment, PFAS have made their way into our water sources.
Is PFAS in my drinking water
PFAS can be found in the drinking water of millions of people around the world. They can contaminate groundwater, surface water, and even municipal water systems. To know if PFAS are in your drinking water, check with your local water provider or consider testing your water.
Health concerns about PFAS
PFAS have been linked to various health issues, including:
- Hormonal disruption
- Immune system dysfunction
- Increased cholesterol levels
- Low birth weight in infants
- Increased risk of kidney and testicular cancer
What level of PFAS is safe
The US Environmental Protection Agency (EPA) has established a health advisory level of 70 parts per trillion (ppt) for the two most common PFAS chemicals, PFOA and PFOS. However, some experts argue that even lower levels may pose health risks.

What is NSF certification?
NSF International is an independent organization that certifies products to ensure they meet strict standards for public health protection. NSF certification involves rigorous testing and evaluation to verify that a product complies with specific standards for safety, quality, and performance.
Clearly Filtered filters certified by NSF
Clearly Filtered filters are certified by NSF International to remove various contaminants, including PFAS. This certification provides assurance that the filters have been independently tested and proven effective in removing PFAS from water.
What does this mean?
NSF certification means that you can trust Clearly Filtered filters to remove PFAS from your water, as they have been independently tested and verified to meet strict safety and performance standards.
Testing Your Drinking Water for PFAS
If you suspect that PFAS may be present in your drinking water, you can have your water tested by an accredited laboratory. These tests can detect PFAS at very low levels and help you determine if your water is safe to drink or if you need to take action to remove the contaminants.
Considerations for Pitcher Filters
Pitcher filters must be maintained to remove PFAS
To ensure that your Clearly Filtered pitcher filter continues to remove PFAS effectively, it’s essential to maintain and replace the filter according to the manufacturer’s recommendations. Over time, the filter’s capacity to remove contaminants can decrease, so regular maintenance is crucial for optimal performance.
