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.

Simply switch on the filter stage
The stainless steel switch lever allows you to quickly switch between filtered and unfiltered water.
Compatible with all standard taps
Thanks to a wide range of adapters, the Duo can be installed on almost all standard taps. Our thread guide will help you find the right adapter.

Filtered or unfiltered?
Thanks to the integrated switch lever, you can quickly and easily switch between filtered and unfiltered water. This protects the filter cartridge and ensures that the full line pressure is maintained when rinsing or filling the watering can.


Fits with or without adapter
Thanks to numerous adapters, the Duo also fits taps with thread sizes that do not correspond to the standard Duo thread of M22.
Select the correct adapter directly when ordering (free of charge).

Does not fit taps with:
- Pull-out fittings (without locking mechanism)
- Sensor technology
- Permanently installed aerators
- Oval or square aerators

What is filtered?
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.
Microplastics and other fine particles
The ultra-fine structure of the sintered activated carbon reliably retains microscopic plastic particles.
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.


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.
