Questions & Answers

What is Alb Filter Duo and does it fit my faucet?

Alb Filter Duo turns your tap fitting into a drinking water dispenser. The drinking water filter is screwed directly to the tap and is installed within a few minutes. It fits most taps in kitchens.

How does it work with the filter cartridges?

Our Alb Filter Duo is a modular filter. This means that you buy the stylish filter housing only once and in future only change the filter cartridge inside every 4 - 6 months. Of course you can also switch between the different versions of our cartridges.

Use of the Alb Duo with pressureless boilers

When using our Alb Filter Duo for the tap, in connection with unpressurized water heaters, please note that due to the high fineness of the cartridge, a pressure is built up in front of it (approximately at the level of the mains pressure), which is only slowly reduced. Under certain circumstances, this can lead to damage to the non-pressure-resistant boiler.

However, there are also pressure-resistant boilers for which the above-mentioned restrictions do not apply. This can be recognised, for example, by the type plate " max. operating pressure ... ". This must be at least 4 bar. However, these boiler types are usually somewhat more expensive to purchase than the unpressurized ones.

As an alternative, we also offer our Alb under-table versions, which are approved for use on unpressurised systems.

How do I know what thread my faucet has?

Most kitchen sinks have an M22 or M24 threaded tap. Included with the Alb Filter Duo housing is a stainless steel adapter for taps with M24 thread. Should it still not fit, Alb Filter offers further adapters in its shop. In order to make sure in advance whether an adapter is required, we advise you to use the thread wizard.

What is the advantage of Alb Filter Duo over a classic Alb Filter?

Alb Filter Duo is not a classic continuous-flow filter, but also allows you to extract the water in your kitchen unfiltered. You can choose between filtered and unfiltered water by means of a selector switch. That's how you protect your cartouche.

When should I filter the water and when not?

Whenever you want to drink water, prepare drinks, clean or prepare food with it, you should use filtered water. Untreated water is also sufficient for rinsing or washing hands.
