Duo Nano
Germ and bacteria filter for the tap
The Duo Nano 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. With its highly effective 0.1 µm hollow fiber membrane, the Nano cartridge effectively keeps bacteria, legionella and microplastics out of the water.
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.
Area of application
The Duo filter housing
Made from 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 odorless and tasteless.
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).

What is filtered?
Microorganisms
The main focus of the Nano cartridge is the filtration of germs and bacteria in high concentrations, e.g. E-Coli, Vibrio Cholarae, Shigella, Salmonella.
Legionella
The Nano cartridge reliably filters legionella from the Tapwater. Whether as a preventative measure or in the event of a positive legionella finding.
Microplastics and other fine particles
Microscopically small plastic particles and other particles are reliably filtered out of the water thanks to the 0.1 µm hollow fiber membrane.
Biofilm-forming microorganisms
Reduces the formation of biofilm and other deposits caused by bacteria.
Stops germs and bacteria
Inside our nano cartridge is a hollow fiber membrane. Similar to bundled straws, this membrane consists of many hollow fibers connected to each other. Due to their small diameter of 0.1 µm, these hollow fiber tubes are able to reliably filter pathogens such as bacteria and germs as well as microplastics and other particles from the water.
Protection against legionella!
The certified quality solution offers maximum protection against Legionnaires' disease. The nano cartridge can be used both preventively and in the event of an actual legionella infestation and protects in accordance with ASTM F838-15A
