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.

Reduces heavy metals

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.
