Wie wechsle ich die Filterkartusche?

Changing the cartridge in an Alb filter is easy and only takes about two minutes. Detailed instructions can be found on the Alb Filter website. It is generally recommended to change the cartridges every 4 to 6 months, depending on usage and water conditions.

Kann ich verschiedene Kartuschen in einem Filtergehäuse verwenden?

Yes, all drinking water and shower filter cartridges from Alb Filter are compatible. This means that you can switch between drinking water and shower filter cartridges as required.

Wie lagere ich die Filterkartuschen nach dem Urlaub?

After a long period of non-use, the cartridges should be removed and dried thoroughly before being stored in a cool, dry place. This prevents the formation of germs and mold.

Wie einfach ist die Installation bzw. Nutzung der Alb Filter?

Wie nachhaltig sind die Produkte von Alb Filter?

Alb Filter attaches great importance to sustainability. The filter housings are reusable and made of durable stainless steel, resulting in less waste. The filter cartridges are also produced in a resource-saving manner and are recyclable.

Warum reduziert sich der Kalkgehalt im Wasser nicht vollständig?

The Active Plus+ filter cartridge reduces limescale using a built-in ion exchanger, but the limescale is not completely removed. Depending on the water hardness, the limescale content is only partially reduced so as not to negatively affect the taste of the water.

Wie verbessert ein Alb Filter den Geschmack meines Wassers?

An Alb filter improves the taste of your water by removing pollutants such as chlorine, pesticides and heavy metals. Activated carbon in the filter cartridges also adsorbs organic compounds such as chlorine, which can cause unpleasant odors and tastes. Certain cartridges, such as the Balance cartridge, add minerals that make the water softer and more appealing in taste

Kann ich die Filter an jeder Art von Wasserhahn installieren?

Yes, the Alb Filter Duo can be installed on most taps without an adapter. To attach the Duo tap filter, you need a thread on the tap. To do this, remove the aerator from your tap and use the Alb Filter thread guide to check whether an adapter is required. For special taps, such as low-pressure taps, we recommend our Under-sink water filters.

Warum sollte ich mein Leitungswasser filtern?

Filtering your tap water offers numerous benefits. It removes pollutants such as chlorine, pesticides, heavy metals and microplastics that could otherwise remain in the drinking water. These pollutants can not only have a negative impact on the taste and smell of the water, but can also pose health risks. A water filter ensures clean, tasty water and helps to reduce the intake of potentially harmful substances. In addition, valuable minerals are retained, which is another advantage over other filter systems such as reverse osmosis.

Duo Active

Pollutant filter for the tap

The Duo Active two-way tap filter only delivers the best drinking water when you really need it. This conserves the capacity of the cartridge and therefore also the environment and your wallet. The Active drinking water cartridge ensures a delicious taste and reduces over 80 harmful substances in Tapwater.

The Duo is available in stainless steel, matt or black and transforms any kitchen tap into a real eye-catcher. The filter housing fits all standard taps with an M22 thread. With the enclosed M24 adapter, the Alb Filter Duo is ready to use in many cases. If a different adapter is required, we will be happy to include it. Ideally, you should determine the thread size of your tap before ordering - you can find instructions in our thread guide.

What is filtered?

Removes odors and bad taste from the water

Chlorine and other taste impairments

The high-quality Alb Filter coconut block activated carbon adsorbs unpleasant odors (chlorine, CHCs, CFCs, etc.) and impairs the taste of drinking water.

Filtration of microplastics in drinking water

Microplastics and other fine particles

The ultra-fine structure of the sintered activated carbon reliably retains microscopic plastic particles.

Reduces pesticides and pharmaceutical residues

Drug residues and pesticides

Organic compounds such as pesticides, herbicides, insecticides, pharmaceutical residues, hormones and hormone-like substances are reduced.

Heavy metals such as lead and copper

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

Binds odors and pollutants

The strong surface forces (adhesion) of the activated carbon remove unwanted turbidity and odors such as chlorine as well as organic compounds and pollutants from the water. These include pharmaceutical residues, hormones, pesticides/pesticides, perfluorinated and polyfluorinated alkyl substances (PFAS), etc.

MechanischeFiltration-ACTIVE.webp__PID:3caa4324-d5e4-40d0-86c2-471ee93a39db

Filters microplastics up to 10µm

The sintered activated carbon has a pore size of just 10µm (0.01 mm). This means that even very small particles are effectively retained by the fine structure. The Active cartridge thus offers protection against microplastics, sand, rust and other particles.

Installation

Unscrew the aerator of the tap.
If necessary, install an adapter on the tap thread.
Then screw the Duo water filter hand-tight to the tap thread or the previously installed adapter using the union nut.
Open the lower cover of the filter housing and press the enclosed cartridge into the cover with a slight twisting motion. Then screw the cover back onto the filter body and tighten it hand-tight.
