Pollutant and germ filter for installation under the sink

The Fusion combines two filter stages in one housing: the Active cartridge reduces pollutants, chlorine and off-flavours, while the Nano cartridge retains 99.999% of all germs and bacteria (0.1 µm, certified to ASTM F838-15A).

The stainless steel housing

Made of high-quality V4A stainless steel

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

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.

Two filter stages in series

Two filter stages in series

In the Fusion housing, two cartridges work one after the other: stage 1 against pollutants (Active or Active PFAS), stage 2 as a germ barrier (Nano). The cartridges can be combined freely.

Modular filter housing

Modular filter housing

The Fusion housing consists of two Element modules with a Connect module and can be extended with the Protect module. With the appropriate adapters, the housing can also be used in a camper van or in the shower.

10-year warranty on the stainless steel housing

10-year warranty on the stainless steel housing

The stainless steel housing comes with a 10-year manufacturer's warranty.

What is filtered?

What is filtered?

The Fusion filters in two stages: stage 1 (Active) binds odours, chlorine and dissolved pollutants, stage 2 (Nano, 0.1 µm) retains germs and bacteria – certified to ASTM F838-15A.

Microorganisms (Nano)

Microorganisms (Nano)

The Nano cartridge focuses on filtering germs and bacteria in high concentrations, e.g. E. coli, Vibrio cholerae, Shigella, Salmonella.

Legionella (Nano)

Legionella (Nano)

The Nano cartridge reliably filters legionella out of tap water. Whether as a preventive measure or following a positive legionella test.

Chlorine and other off-flavours (Active)

Chlorine and other off-flavours (Active)

The high-quality Alb Filter coconut activated carbon block adsorbs unpleasant odours (chlorine, CHCs, CFCs and much more) and off-flavours in drinking water.

Pharmaceutical residues and pesticides (Active)

Pharmaceutical residues and pesticides (Active)

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 (Active)

Heavy metals such as lead and copper (Active)

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

Microplastics and other fine particles

Microplastics and other fine particles

The pores of the hollow-fiber membrane are about 700 times finer than a hair (0.1 µm) – microscopically small plastic particles and other particles can't get through.

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.

Binds odours and pollutants

Retains microplastics

The sintered activated carbon has pores of only 10 µm – about 7 times finer than a human hair. Microplastics, sand, rust and other particles reliably get caught in them.

Retains microplastics

Stops germs and bacteria

Inside the Nano cartridge is a hollow-fiber membrane made of thousands of ultra-thin tubes, similar to bundled drinking straws. Its pores measure just 0.1 µm – about 700 times finer than a human hair and therefore smaller than bacteria. This keeps out germs, bacteria and legionella as well as microplastics and other particles.

Stops germs and bacteria

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).

  1. Assembly overview of the Fusion with the standard connection kit: angle valve, flex hose (1), Fusion filter housing (2), thread adapter (3) and inlet hose

    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.

  • Cordula Verified buyer Duisburg, DE · 21 days ago

    Friendly customer service, questions were answered and easy to reach by phone. I compared various water filter systems and decided on Alb Filter. The installation was easy, despite a little 2-year-old who found it all very exciting and was included in the process. The hoses could be a bit longer. My daughter and her family really like the taste of the water.

    Freundlicher Kundenservice, Fragen wurden beantwortet und telefonisch gut erreichbar. Habe verschiedene Wasserfilter Systeme verglichen, und mich für die Alb Filter entschieden. Die Montage war leicht, trotz einem kleinen, 2jährigen, der das sehr spannend fand und mit einbezogen wurde. Die Schläuche könnten etwas länger sein. Meiner Tochter und ihrer Familie schmeckt das Wasser sehr gut.

    Super easy for fitting the filter. Matching connections are important.

  • Anonym Verified buyer Biberach, DE · 3 months ago

    The installation size is very well suited to under-sink installation. The enclosed instructions are absolutely sufficient. It is still too early to judge the resulting water quality, as it was only installed 4 days ago.

    Installationsgröße ist sehr gut für Untertischeinbau geeignet. Beiliegende Beschreibung absolut ausreichend. Für eine Beurteilung der erzeugten Wasserqualität ist es noch zu früh, da Einbau erst vor 4 Tagen erfolgt.
