PFAS water filters
Effective protection against forever chemicals: the Alb Active PFAS systems filter short- and long-chain PFAS out of your tap water – while also reducing over 80 other pollutants such as chlorine, microplastics and pharmaceutical residues.
Our PFAS filters
Whether on the tap or under the sink: all systems use the Active PFAS cartridge with patented absorber resin.

What is filtered?
PFAS
High filtration performance for long- and short-chain PFAS such as perfluorobutanesulfonic acid (PFBS) and perfluorobutyrate (PFBA).
Chlorine and other off-flavours
The high-quality Alb Filter coconut block activated carbon adsorbs unpleasant odours (chlorine, CHCs, CFCs and much more) and off-flavours in drinking water.
Microplastics and other fine particles
Thanks to the very fine structure of the sintered activated carbon, even the tiniest plastic particles are reliably retained.
Pharmaceutical residues and pesticides
Organic compounds such as pesticides, herbicides, insecticides and pharmaceutical residues, as well as hormones and hormone-like substances, are reduced.
Heavy metals such as lead and copper
The adsorptive effect of the activated carbon binds and reduces heavy metals in drinking water.
How the Active PFAS cartridge works
Fine block retains particles
The pores of the sintered activated carbon are about 14 times finer than a human hair. Microplastics, sand and rust get caught in them.
Activated carbon binds odors and pollutants
Activated carbon works like a sponge with a huge internal surface area: chlorine, pharmaceutical residues, hormones and pesticides stick to it, while minerals flow through.
PFAS resin works like a magnet
At the core is an ion exchange resin: the negatively charged PFAS particles stick to the positively charged resin beads – both long-chain and short-chain. RadiantFlow® technology ensures that the water flows through the resin evenly.
Development partner
Developed with instrAction® from Heidelberg
The absorber resin of the Active PFAS cartridge was created in close collaboration with instrAction® from Heidelberg, a specialist in innovative filter media. The P absorber resin was developed and tested for over ten years – Made in Germany.
- High selectivity for short- and long-chain PFAS
- Fast adsorption even at high flow rates
- Stable performance across the entire pH and temperature range
"The Active PFAS cartridge shows that our patented absorber resin can ensure highly effective PFAS retention to below the detection limit, even in compact systems such as the Alb Filter!"

What are PFAS?
Forever chemicals: PFAS (per- and polyfluoroalkyl substances) are a group of more than 10,000 industrial chemicals. Because of their water-, grease- and dirt-repellent properties, they have been used since the 1940s in outdoor clothing, pan coatings, packaging or firefighting foam. They barely break down in nature and accumulate in soil, waterways and the human body.
How PFAS get into drinking water: Via wastewater, contaminated soil and past use of firefighting foam, PFAS seep into the groundwater – and from there into the mains network. Because these substances are water-soluble and extremely stable, they spread over wide areas.
How big is the problem? The Federal Office for the Environment (FOEN) detected PFAS at just under half of Switzerland's groundwater monitoring sites (measurements from 2021) – at around 2% of them, the total exceeded 0.1 µg/l. That is the sum value the EU sets for 20 PFAS in drinking water. Even if your water supplier complies with the requirements, traces may be present in your drinking water.

FAQs on PFAS and PFAS water filters
Understanding PFAS
What exactly are PFAS and why are they called ‘forever chemicals’?
PFAS are synthetic chemicals that make products water- and dirt-repellent. They hardly break down at all and remain in the environment and the body for decades – hence the name.
Are PFAS really dangerous for me and my family?
Studies link PFAS to immune deficiency, raised cholesterol, thyroid problems, developmental disorders in children and an increased risk of cancer. Pregnant women, children and people with long-term exposure should be particularly careful.
Which types of PFAS do Alb Filter products filter exactly?
Our systems reduce both long- and short-chain compounds such as perfluorobutanesulfonic acid (PFBS) and perfluorobutyrate (PFBA) – reliably, in a single step. This matters because short-chain PFAS are increasingly used as substitutes and are harder to filter.
How effective is the filtration compared with the PFAS maximum values?
In Switzerland, the Drinking Water Ordinance (TBDV) sets maximum values for individual PFAS – 0.3 µg/l for PFOS and PFHxS and 0.5 µg/l for PFOA. The federal government plans to adopt the stricter EU sum value of 0.1 µg/l (100 ng/l) for 20 relevant PFAS. Alb Filter systems with the Active PFAS cartridge often lower PFAS concentrations to below the detection limit – extra safety, even if your tap water is close to the maximum values.
Alb PFAS filters in practice
What makes the Active PFAS cartridge so special?
The Active PFAS is a specially developed cartridge with a core of PFAS absorber resin (anion exchanger), which binds negatively charged PFAS ions almost ‘magnetically’. Combined with sintered coconut activated carbon and RadiantFlow® technology for an even flow, long- and short-chain PFAS are effectively reduced – often to below the analytical detection limit.
What other pollutants does the Active PFAS cartridge filter?
In addition to PFAS, it reduces chlorine and chlorine-related off-tastes, odours (e.g. CHCs, CFCs), microplastics down to 5 µm, pharmaceutical residues, pesticides, herbicides, insecticides, hormones and heavy metals such as lead and copper. Important: the minerals (e.g. calcium and magnesium) are retained – your water tastes naturally fresh.
How often do I need to replace the PFAS filter?
On average, the PFAS cartridge should be replaced after 3,000–5,000 litres or around 4 months – depending on water consumption and initial water quality. For a family of 4 (approx. 8–12 litres of drinking water per day), the cartridge usually lasts the full 4 months. The change only takes seconds.
What is the difference between the Duo Active PFAS on the tap and the under-sink filter?
The Duo Active PFAS is the tap filter with a diverter lever: you switch between filtered and unfiltered water in a flash – this saves cartridge capacity when washing up and maintains full mains pressure.
The Active PFAS under-sink filter is installed out of sight under the sink and supplies your kitchen with filtered water at all times – ideal for a permanent, discreet solution.
Will the Active PFAS cartridge fit my existing Alb Filter system?
Yes – the cartridge is compatible with all Alb drinking water filter housings such as Element, DUO and Fusion. Unscrew the old cartridge, screw in the new one, rinse briefly – done. Ideal if you already have an Alb Filter and want to upgrade it specifically to protect against PFAS.
Why is an Alb Filter worthwhile against PFAS compared with other methods?
Compared with reverse osmosis (which uses a lot of water and removes minerals) or simple jug filters, Alb Filter is practical, resource-efficient and specifically optimised for PFAS: high flow rate, no electricity required, minerals retained and Made in Germany quality.
