Pairs perfectly with this
The PFAS specialist under the sink
The only under-sink filter in the Element range specifically optimised against ‘forever chemicals’: an ion-exchange absorber resin binds long- and short-chain PFAS, while the sintered activated carbon stage (5 µm) takes care of chlorine, off-flavours, microplastics and heavy metals.
The stainless steel housing
Made of high-quality V4A stainless steel
The robust and durable stainless steel housing is free of harmful substances, corrosion-resistant, easy to clean, germ-resistant and neutral in odour and taste.
Direct connection to the cold-water angle valve
Our connection kits include all the parts needed to mount the housing directly on the cold water angle valve under the sink.
One housing, four cartridges
Choose from our drinking water cartridges Active, Active+, Active PFAS and Nano, or combine them to cover the maximum filter spectrum.
Modular filter housing
The housing can be extended with an additional filter stage (Fusion) and supplemented with the Protect module. With the appropriate adapters, the housing can also be used in a campervan or in the shower.
10-year warranty on the stainless steel housing
The stainless steel housing comes with a 10-year manufacturer's warranty.
Made in southern Germany
Our water filters are manufactured in southern Germany and are subject to Alb Filter's high standards of quality and durability.
What is filtered?
Active PFAS cartridge made of sintered activated carbon with PFAS absorber resin: the ion exchange resin binds long- and short-chain PFAS, while the activated carbon stage (5 µm) takes care of chlorine, off-flavours, microplastics and heavy metals.
PFAS – long- and short-chain
The ion exchange absorber resin reliably binds long- and short-chain forever chemicals such as PFBS and PFBA.
Chlorine and other off-flavours
The sintered coconut block activated carbon (5 µm) adsorbs unpleasant odours (chlorine, CHCs, CFCs and much more) and off-flavours in drinking water.
Microplastics and other fine particles
The pores of the activated carbon stage are around 14 times finer than a hair (5 µm) – microscopically small plastic particles and other particles are reliably trapped.
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.
PFAS absorber resin core
The ion exchange resin used to reduce long- and short-chain PFAS binds the contaminants like a magnet. The negatively charged PFAS ions are held in place by the positively charged anion resins, preventing them from being carried any further.
The patented RadiantFlow® technology ensures an even flow through the filter medium and delivers a high, reliable filtration effect throughout the entire working area of the granulate.
Binds odours and pollutants
The strong surface forces (adhesion) of the activated carbon remove unwanted cloudiness and odours such as chlorine from the water, as well as organic compounds and pollutants. These include pharmaceutical residues, hormones, pesticides/plant protection products, per- and polyfluoroalkyl substances (PFAS) and many more.
Retains microplastics
The activated carbon stage has pores of only 5 µm – around 14 times finer than a human hair. Microplastics, sand, rust and other particles are reliably trapped in them.
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!"
Dr. Christian Meyer, Head of Production and Synthesis – instrAction®
Easy filter change without tools
With the quick-coupling connection kit, you can change the cartridge in a few seconds – without any tools. The integrated water stop prevents residual water from leaking out during the change.
Before changing, simply close the water supply at the angle valve – done.
Optionally with Protect pre-filter
The Protect module protects your main cartridge from coarse particles such as rust, sand and sediment (filter pad 40 µm), thereby extending its service life. Particularly useful with old pipes or unknown water quality.
Installed between the lid and the housing in just a few seconds.

Frequently asked questions
Will the filter fit under my sink?
The Element housing is 122 mm high (Fusion: 227 mm, with quick couplings + approx. 7 cm). It is mounted upright or with an optional wall bracket on the cold water angle valve – this fits into almost any sink cabinet.
Do I need a 3-way tap?
No. The filter works with any cold water connection. A 3-way tap is ideal if you want to draw filtered and unfiltered water separately to save filter capacity.
How often do I need to change the cartridge?
Active cartridges every 4 months, the Nano cartridge every 6 months – depending on water quality and consumption.
Can I install the filter myself?
Yes. Connecting it to the angle valve takes just a few minutes and doesn't require a professional – the connection kit and instructions are included.
What happens during holidays or longer breaks?
If the filter has not been used for a while, simply let the water run for 20–30 seconds. If you're away for several weeks, we recommend removing the cartridge, storing it in a cool place and flushing it before use.

Raimund Verified buyer
I'm very satisfied with the filter. I managed the installation wonderfully and I also ordered a tap for the sink. I'm really no handyman and it still worked out well. It's really very easy to handle. You just shouldn't turn the tap on too hard, but let the water run through slowly, as the manufacturer recommends. The taste is super and since I drink a lot of water, it's really worth it for me!

Ich bin sehr zufrieden mit dem Filter. Den Einbau habe ich wunderbar hinbekommen und ich habe mir auch noch einen Wasserhahn für die Spüle bestellt. ich bin wirklich kein Handwerker und es hat trotzdem gut geklappt.Es ist wirklich sehr einfach zu handhaben. Man sollte nur den Hahn nicht zu doll aufdrehen, sondern das Wasser langsam durchlaufen lassen so wie es der Hersteller empfiehlt. Der Geschmack ist super und da ich viel Wasser trinke, lohnt es sich für mich wirklich!

Quick coupling is a must. It makes filter changes etc. extremely easy. Water pressure is (as expected) a bit lower because of the filter, but having clean, pure water is definitely worth it.

Schnellkupplung ist ein Muss. Es vereinfacht Filterwechsel etc extrem. Wasserdruck ist durch den Filter (wie erwartet) etwas geringer, aber das ist es auf jeden Fall Wert sauberes, reines Wasser zu haben.

Marita Verified buyer
Very good under-sink filter with strong PFAS performance. Water is clearer and more neutral in taste. Installation went well too (quick coupling recommended!). The flow rate does get a bit lower, though. But I'm happy to accept that for the reduction in pollutants.

Sehr guter Untertischfilter mit starker PFAS-Performance. Wasser ist klarer und neutraler im Geschmack. Einbau ging auch gut (Schnellkupplung empfehlenswert!). Der Durchfluss wird allerdings etwas geringer. Für die Schadstoff Reduktion nehme ich das aber gerne in Kauf.
