Pollutant filter for installation under the sink

The under-sink water filter provides pure, great-tasting drinking water straight from the tap. The BIOTON filter cartridge not only protects against pollutants, but also improves the taste of the water and filters out the finest particles such as microplastics and germs down to a size of 0.7 µm. The cartridge also helps to reduce visible limescale stains.

Once installed under the sink, the water filter delivers top-quality drinking water whenever the cold water tap is turned on. Also ideal for 3-way taps.

What is filtered?

What is filtered?

Active Plus+ cartridge with Bioton filter material: the activated carbon stage binds odors, chlorine and dissolved pollutants, the ion exchanger reduces limescale by approx. 4–6 °dH – and the fine pores also mechanically retain particles and bacteria.

Chlorine and other off-flavours

Chlorine and other off-flavours

The Bioton cartridge adsorbs unpleasant odours (chlorine, chlorinated hydrocarbons, CFCs and much more) and off-flavours in drinking water.

Limescale – noticeably softer water

Limescale – noticeably softer water

The ion exchanger reduces carbonate hardness by approx. 4–6 °dH – fewer limescale stains on glasses and in the kettle.

Microplastics and other fine particles

Microplastics and other fine particles

The pores of the Bioton cartridge are around 100 times finer than a hair (0.7 µm) – microscopically small plastic particles and other particles are reliably trapped.

Germs and bacteria

Germs and bacteria

The 0.7 µm germ barrier retains germs and bacteria purely mechanically – without chemicals.

Pharmaceutical residues and pesticides

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

Heavy metals such as lead and copper

The adsorptive effect of the activated carbon binds and reduces heavy metals in drinking water.

Binds odours and pollutants

Thanks to the strong surface forces (adhesion) of BIOTON, unwanted turbidity and odours such as chlorine, but also organic compounds and pollutants, are filtered out of the water. These include pharmaceutical residues, hormones, pesticides/plant protection products, per- and polyfluoroalkyl substances (PFAS) and many more.

Binds odours and pollutants

Retains microplastics and bacteria

Bioton has pores of only 0.7 µm – around 100 times finer than a human hair. Sand, rust and microplastics are trapped in them, and bacteria are also mechanically retained. Certified germ protection is provided by the Nano cartridge.

Retains microplastics and bacteria

Limescale reduction through ion exchange (softening effect)

In water treatment, softening (limescale reduction) of the water is achieved through the chemical process of “ion exchange”. With the help of cation and anion exchangers, unwanted salts are removed from the water. For example, one calcium molecule is replaced by two sodium molecules.

When the water exits the fine channels, the pressure drops abruptly. In the process, part of the limescale (Ca²⁺) is converted into aragonite. Aragonite has a different structure from limescale and adheres much less to surfaces – which reduces annoying limescale stains.

Limescale reduction through ion exchange (softening effect)

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.

Easy filter change without tools

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.

Installation

With the connection kits, you can easily mount the Alb Filter system under the kitchen sink on the angle valves. The connection is made to the cold water supply.

To make sure your filter works reliably from the start, please read the included step-by-step instructions before the first installation. They describe how to mount the connection kits as well as how to correctly install the filter cartridges and put the system into operation. The instructions for download: Under-sink user manual (PDF).

    Installing the standard connection kit

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.

  • Thomas Verified buyer Bielefeld, DE · 24 days ago

    To be honest, I would have liked a stronger reduction of the limescale content in my water. Using test strips, I couldn't see much difference between filtered and unfiltered water. You'd think that wouldn't be so hard, since suppliers like Brita manage it with their tabletop water filter jugs, and you don't necessarily want to go straight for a reverse osmosis system. But, as I then learned from my communication with Alb-Filter, that isn't necessarily the main focus of this filter. Shame. But I'll keep an eye on whether the …

    Tatsächlich hätte ich mir eine stärkere Reduzierung des Kalkgehalts in meinem Wasser gewünscht. Ich konnte auf Teststreifen mit gefiltertem und ungefiltertem Wasser keinen großen Unterschied erkennen. Man sollte ja meinen, dass das nicht so schwer wäre, da Anbieter wie Brita das mit ihren On-Table-Wasserfilterkannen ja auch hinbekommen, und man nicht unbedingt gleich zu einer Umkehrosmose-Anlage greifen möchte. Aber, wie ich aus der Kommunikation mit Alb-Filter dann erfuhr, liegt darauf nicht unbedingt der Hauptaugenmerk bei diesem Filter. Schade. Aber ich beobachte mal, ob sich die …
