The germ barrier for your kitchen

The under-sink filter with Nano cartridge retains 99.999% of all germs and bacteria – certified to ASTM F838-15A. The right choice for old pipes, a positive legionella test or the highest hygiene requirements.

The germ barrier for your kitchen

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.

One housing, four cartridges

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

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.

What is filtered?

What is filtered?

Nano cartridge with 0.1 µm hollow-fibre membrane: it retains 99.999% of all germs and bacteria purely mechanically – certified according to ASTM F838-15A, at a full flow rate of approx. 11 l/min.

Microorganisms

Microorganisms

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

Legionella

Legionella

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

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.

Biofilm-forming microorganisms

Biofilm-forming microorganisms

Reduces the formation of biofilm and other deposits caused by bacteria.

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

Protection against legionella!

This certified quality solution offers maximum protection against Legionnaires' disease. The Nano cartridge can be used both preventively and in the event of acute legionella contamination and provides protection in accordance with ASTM F838-15A.

Protection against legionella!

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.

Optionally with Protect pre-filter

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 standard connection kit: angle valve, flex hose (1), filter housing (2), thread adapter (3) and inlet hose

    Installing the standard connection kit

    1. Flexible hose with 1/2“ male thread and 3/8“ female thread
    2. Filter housing (note the flow direction – marked with an arrow and IN)
    3. Thread adapter: 3/8“ male thread × 1/2“ female thread
  2. Assembly overview of the connection kit with quick couplings: angle valve, flex hose (1), quick couplings (2, 3), filter housing (4), quick couplings (5, 6) and inlet hose

    Installing the connection kit with quick couplings

    1. Flexible hose with 1/2“ male thread and 3/8“ female thread
    2. Quick coupling plug with 1/2“ female thread
    3. Quick coupling with 1/2“ male thread
    4. Filter housing (note the flow direction – marked with an arrow and IN)
    5. Quick coupling plug with 1/2“ female thread
    6. Quick coupling with 3/8“ male thread

You can find more information on installation in the included installation instructions and in our installation help.

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.

    Meine Erwartungen sind voll aufgegangen, und sind sehr zu empfehlen. Ich habe bereits eine Anlage im Wohnwagen verbaut. Einfach Super.

  • Cris Verified buyer Athens, GR · 1 year ago

    Good flow rate, although the (filter) quality hasn't been tested yet. The roughened surfaces/rings are actually good but unnecessarily sharp-edged. The instructions supplied are extensive but confusing, as they cover all filter types.

    Guter Durchfluss, wobei die (Filter-)Qualität noch nicht getestet wurde. Die aufgerauten Oberflächen/Ringe sind eigentlich gut aber unnötig scharfkantig. Die mitgelieferte Anleitung ist umfangreich, aber verwirrend, da alle Filtertypen behandelt werden.

  • Dirk Verified buyer Westoverledingen, Deutschland · 1 year ago
