Reduce Pfoa in Water

Die Reduzierung von PFOA im Trinkwasser ist ein wichtiger Schritt, um die Gesundheit Ihrer Familie zu schützen. Diese vom Menschen hergestellte Chemikalie steht im Verdacht, gesundheitliche Probleme zu verursachen, wenn sie in zu großen Mengen in den Körper gelangt. Die gute Nachricht ist: Es gibt einfache und zugleich effektive Methoden, PFOA aus dem Wasser herauszufiltern.
In diesem Blogbeitrag von Frizzlife stellen wir Ihnen diese Methoden im Detail vor – also verlieren wir keine Zeit und legen gleich los!

A short introduction to Pfoa

PFOA stands for perfluorooctanoic acid. It's a man-made chemical that is very difficult to break down in our environment and our bodies. It has been used for many years to make non-stick cookware and stain-resistant coatings.
Some studies suggest that long-term, high-level PFOA exposure may increase the risk of cancer or cause other health problems. Most people carry small amounts of PFOA in their bodies—for example, through eating food stored in plastic packaging.

How can you reduce Pfoa in drinking water?

Installation of a reverse osmosis filter
A reverse osmosis system is ideal for removing PFOA. This method forces water through a special membrane that acts like a sieve, trapping tiny PFOA molecules so they don't enter the purified water.
Reverse osmosis filters remove over 90% of PFOA. All you need to do is replace the filter cartridges every 6 to 12 months, depending on your household's water usage.

Use of activated carbon filters
Activated carbon filters are another highly effective option. These filters contain a special carbon material that attracts and binds contaminants like PFOA. The carbon draws the molecules into its numerous fine pores and safely stores the chemicals inside.
When purchasing a filter, make sure it's certified to reduce PFOA. Remember to replace the filter cartridge regularly—usually every six months—to maintain its filtration efficiency. Compared to other methods, activated carbon filters are very cost-effective to operate and maintain.

Use of point-of-use filters
Point-of-use filters offer a convenient way to treat water precisely where you drink it—for example, directly at the faucet or under the sink. These filters work similarly to central home filtration systems: They capture PFOA and other contaminants, but only treat the water at a specific point of use.
When choosing filters, look for ones certified to reduce PFOA. Remember to replace the cartridge regularly—usually every 2 to 6 months—to maintain filtration efficiency. Point-of-use filters are easy to install and maintain, providing you with clean drinking water without having to filter all of your water in your home.

frequently asked Questions

Is there a way to test my water for PFOA?

Yes, there are several ways to test your water for PFOA contamination. Many municipalities conduct regular PFOA tests as part of their standard water quality monitoring. You can also contact your local water supplier and ask about the latest test results. Private laboratories like Eurofins offer PFOA water test kits that you can purchase online and send in yourself. These provide accurate results within a few weeks. Another option is to hire a professional water testing company to take samples from your taps. They will analyze the water and provide a detailed report on any contaminants found, including PFOA levels. Testing is a good way to assess your water quality and determine if treatment is necessary.

Can boiling water reduce PFOA?

No, boiling water does not remove PFOA. This is because it is a fairly stable chemical that neither breaks down nor evaporates when boiled. The recommended approach is to use various filtration techniques for effective removal. How often should I change my filter to ensure PFOA removal? While there is no fixed timeframe, you should maintain the filter according to the manufacturer's instructions.
