PFAS 101: Your Top 5 Frequently Asked Questions Answered

Below are answer to the top 5 frequently asked questions about PFAS:

How are people exposed to PFAS?

PFAS can be found in a wide range of products and materials, including non-stick cookware, food packaging, stain-resistant carpeting, and firefighting foam. As a result, exposure to these chemicals can occur through a variety of routes, including ingestion, inhalation, and dermal contact.

One of the most common ways people are exposed to PFAS is through contaminated drinking water. PFAS chemicals are highly resistant to degradation, which means they can persist in the environment and accumulate in water sources over time. This is particularly concerning for communities located near military bases, airports, and other industrial sites where PFAS-containing firefighting foam has been historically used.

Another potential source of PFAS exposure is through the use of certain consumer products, such as non-stick cookware and stain-resistant fabrics. When these products are heated or washed, they can release PFAS chemicals into the air or water, which can be inhaled or ingested by humans and animals.

To reduce your risk of exposure to PFAS, it’s important to be aware of the products and materials that contain these chemicals and to take steps to reduce your use of them whenever possible. This may include using alternative cookware and cleaning products, filtering your drinking water, and avoiding products treated with stain-resistant coatings.

What filter removes pfas from drinking water?

If you’re concerned about PFAS contamination in your drinking water, one of the most effective ways to reduce your exposure is by using a water filter that is specifically designed to remove these chemicals.

One type of filter that is particularly effective at removing PFAS is known as activated carbon. This type of filter works by adsorbing (not absorbing) the chemicals onto its surface, effectively removing them from the water. However, not all activated carbon filters are created equal, and some may be more effective than others at removing PFAS.

Another type of filter that has been shown to be effective at removing PFAS is reverse osmosis. This type of filter uses a semi-permeable membrane to remove impurities from the water, including PFAS. However, reverse osmosis filters can be more expensive and require more maintenance than activated carbon filters.

No matter which type of filter you choose, it’s important to select one that is certified to remove PFAS. Look for filters that have been tested and certified by organizations such as NSF International or the Water Quality Association.

How do you test tap water for PFAS?
