Can you filter PFAS from drinking water?
Do you want to filter PFAS from drinking water? Yes, you can. But not with every filter. PFAS are difficult to remove and require specific filtration techniques. Below we explain the most effective methods.
Which filters work against PFAS?
1. Activated Carbon Filters
Filtering PFAS from Drinking Water with Activated Carbon is one of the most commonly used materials to filter PFAS. It binds chemicals to the surface and can, in particular, long chain PFAS (such as PFOS and PFOA) effectively. Please note: not all carbon filters are equally powerful. Granular activated carbon (GAC) generally performs better than compact blocks, provided they are properly maintained.
2. Reverse Osmosis (RO)
Filtering PFAS from Drinking Water with An RO system pushes water under high pressure through a semi-permeable membrane. Even the smallest particles, including PFAS, are left behind. Reverse Osmosis is one of the most effective techniques, but requires an investment and installation under the sink. RO is often combined with activated carbon for optimal operation.
3. Ion Exchange Filters
This technique involves exchanging PFAS molecules with harmless ions. Ion exchangers are effective for both long and short chain PFAS. They are often used in industrial applications, but are also available for household use.
4. Combination systems
The best filters combine multiple technologies: activated carbon, RO and ion exchange. These systems offer higher filtration efficiency, but are also usually more expensive and larger in size.
What doesn't work against PFAS?
Many simple water filters such as jugs with standard cartridges (without high quality activated carbon) or simple tap filters do not remove PFAS or only remove a few. Boiling does not help either – PFAS do not evaporate at 100 degrees.
What should you pay attention to when choosing a PFAS filter?
1. Independent test results
Always check that the filter has been tested for PFAS removal by independent laboratories, such as NSF International or TÜV.
2. Type of PFAS
Ask whether the filter can also remove short-chain PFAS, as these are even more difficult to filter and are increasingly found in water.
3. Maintenance and replacement
Filters lose their effectiveness over time. Pay attention to the replacement schedule and availability of cartridges or membranes.
4. Capacity and ease of use
If you have a family or drink a lot of water, choose a filter with sufficient capacity and a fast flow rate.
What are the best PFAS filters for home use?
What does the government say about PFAS in drinking water?
In 2023, the European Union will have a joint PFAS limit value set for drinking water: 100 nanograms per liter for sum of 20 PFAS, and 500 nanograms for total PFAS. The Netherlands has adopted these guidelines. However, exceedances are still regularly reported, especially near industrial areas.
Why is PFAS so difficult to remove?
PFAS are molecularly strong and do not dissolve well in water, making them difficult to filter. The fluorocarbon chains also make them chemically stable. Therefore, removing PFAS often requires a combination of techniques and precise filtration down to the nano level.
What can you do yourself besides filtering?
In addition to filtering your tap water, you can limit PFAS exposure by:
- Do not use pans with Teflon coating
- Avoid cosmetics with 'fluorine' or 'PTFE' in the ingredients list
- Do not use water-repellent sprays indoors
- Choose products with eco-labels

By filtering PFAS from drinking water, you reduce the risk of health problems caused by long-term exposure to these harmful substances.
Water without PFAS: is it possible?
Completely PFAS-free water is difficult to guarantee, but a good filter can get you close. PFAS are widespread and enter our drinking water through various sources. By being mindful of water consumption and using certified filtration systems, you can significantly reduce exposure. Consider using filtered water for other kitchen tasks, such as cooking and making coffee. This ensures water with no or very low PFAS concentrations in your household.
Filtering PFAS from tap water: practical tips
To filter PFAS from tap water, you can start with a jug filter as a temporary solution, but for maximum protection, a faucet filter or an under-sink system is more effective. Make sure you choose a model with clear test reports and replace the filters regularly. Pay attention to water pressure and installation requirements. Good preparation makes all the difference. By filtering PFAS from drinking water this way, you immediately improve the water quality in your home.
Filtering tap water against PFAS
Tap water in the Netherlands contains traces of PFAS in some regions. Filtering tap water is therefore essential for health and safety. Besides filters on the tap or in the kitchen, you can opt for a central filtration system for your entire house. This allows you to filter not only your drinking water, but also the water you use for showering and cooking. This is especially useful if you live in an area where PFAS is present in higher concentrations.

Frequently Asked Questions (FAQ)
Does a standard water filter jug remove PFAS?
Not always. Only filter jugs with high-quality activated carbon or extra filter layers can (partially) remove PFAS. Look at independent test results.
Are PFAS harmful in small quantities?
Even small amounts of PFAS can accumulate in the body. Long-term exposure is associated with health risks, especially in children and pregnant women.
How often should I replace a PFAS filter?
It depends on the type of filter and the amount of water you use. Some filters need to be replaced monthly, others last 6 months to a year. Always follow the manufacturer's guidelines.
Can I completely remove PFAS from my water?
With advanced systems like reverse osmosis combined with activated carbon you can remove most of the PFAS. Complete removal is difficult, but you can drastically reduce exposure.
Are PFAS also dangerous through showering or bathing?
PFAS are mainly absorbed through ingestion (drinking or eating). Absorption through the skin is limited, but with long or hot showers there can be slight exposure through inhalation or skin contact.
PFAS in our tap water? It sounds like a futuristic problem, but it is the harsh reality. More and more Dutch people are concerned about the quality of their drinking water. Rightly so. Because PFAS – a group of persistent chemicals – are difficult to break down, potentially harmful to health and now widespread in our environment. In this article you will discover how to PFAS drinking water can filter, which methods really work and what to look for when choosing a PFAS water filter.
What exactly are PFAS?
PFAS stands for Per- and Polyfluoroalkyl substances, a collective name for thousands of synthetic substances that have been used since the 50s in, among other things, pans with non-stick coatings, rain gear, cosmetics and fire-fighting foam. They are water- and grease-repellent, but above all: extremely persistent. They hardly break down in the environment and in our bodies. That is why they are also called 'forever chemicals'.
Filtering PFAS from Drinking Water: How Does it End Up in Our Drinking Water?
PFAS can end up in our surface and groundwater via industrial discharges, agricultural land, landfills and even the air. Because our tap water often comes from these sources, traces of PFAS can end up in drinking water. Although drinking water companies do their best to remove PFAS, they are not always completely successful.
Are PFAS in drinking water dangerous?
Scientific studies link long-term exposure to PFAS to various health problems. Think of:
- Hormonal disruptions
- Increased risk of kidney and liver problems
- Elevated cholesterol levels
- Reduced functioning of the immune system
- Lower fertility
Although the amounts of PFAS in Dutch drinking water are usually below the legally permitted standards, more and more people are choosing to be safe than sorry. Read more about PFAS Drinking Water
