Pre-filter for Duo Nano tap filter

The pre-filter extension for the Alb Filter Duo Nano tap filter to protect the Nano filter cartridge.
Effective against coarse dirt such as pipe deposits, sediment, rust, sand and much more.

Why might the pre-filter be useful?

In certain installation situations (old buildings etc.), pipe deposits, sand, sediment, rust, particles or suspended matter can clog the individual hollow-fibre membranes of the Nano cartridge much more quickly and reduce the service life of the filter cartridge. The replaceable 40 µm pre-filter cap (pat.) ensures coarse pre-filtration and increases the lifespan.

How is the pre-filter used?

The pre-filter is slipped directly over the inlet opening of the Nano cartridge. See image.

    Hello, the first time I only ordered the Nano cartridge, the water quality is on another level the second time I also ordered a pre-filter for the coarser particles and at the latest change 3 weeks ago I got a shock when I saw the pre-filter. it had mutated from white to medium brown and looked like liquid c..p I don't want to imagine what I had been drinking before without the Alb filters, because I believed that German water was the best, "most controlled" foodstuff, but thanks to the company Alb, who have such an effective system …
