Pure drinking water right in your kitchen

The entry-level model for under-sink filtration: the Element housing with Active cartridge is mounted on the cold water angle valve, where it takes up little space, and reduces pollutants, chlorine, microplastics and heavy metals – at full flow rate.

Ideal in combination with a 3-way tap, but works on any cold water connection.

What is filtered?

What is filtered?

Active cartridge made of sintered coconut activated carbon block. The Active cartridge works in two ways: adsorption binds odours, chlorine and dissolved pollutants, while mechanical filtration retains particles down to 10 µm – at a full flow rate of approx. 7 l/min.

Chlorine and other off-flavours

Chlorine and other off-flavours

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

Microplastics and other fine particles

Microplastics and other fine particles

Thanks to the ultra-fine structure of the sintered activated carbon, microscopic plastic particles are reliably retained.

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

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

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)

    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.

    I had the aluminium version before; the stainless steel one is noticeably sturdier - especially the fine thread. What I'm missing is a clear marking of the flow direction on the lids, like In and Out. On the housing it doesn't help much once I've taken everything apart, as the lids fit on either side.

    Hatte vorher die Alu-Variante, die in Edelstahl ist merklich robuster - vor allem das Feingewinde. Was mir fehlt, ist eine eindeutige Markierung der Flussrichtung auf den Deckeln, wie In und Out. Auf dem Gehäuse hilft sie nicht viel, wenn ich alles zerlegt habe, da die Deckel auf jede Seite passen.

    Under-sink drinking water filter does exactly what it's supposed to. ​Plus points: ​Easy cartridge change: Thanks to the click system, the filter change is done in seconds, with no tools at all. ​Compact: Takes up hardly any space in the cupboard under the sink. ​The water pressure at the tap is minimally weaker than before, but that's normal with filters. ​All in all a great product for everyday use. I would buy it again

    Untertisch Trinkwasserfilter tut genau das, was er soll. ​Pluspunkte: ​Einfacher Kartuschenwechsel: Dank des Klick-Systems ist der Filterwechsel in Sekunden erledigt, ganz ohne Werkzeug. ​Kompakt: Nimmt im Unterschrank kaum Platz weg. ​Der Wasserdruck ist am Wasserhahn minimal schwächer als vorher, was aber bei Filtern normal ist. ​Insgesamt ein klasse Produkt für den Alltag. Würde ich wieder kaufen
