Will the Alb Filter® DUO fit my tap?
Guidebook Guidebook
Yes! In 85% of cases, you probably have either a tap with an M22 or M24 threaded connection. An additional stainless steel adapter for M24 threads is included in the scope of delivery. For all other taps, we have additional adapters in our store.
It is best to measure the thread of your tap before ordering and select the appropriate adapter directly when ordering. You will then receive the correct adapter free of charge with your order. You can easily check which adapter you need with our small Guidebook .
Alternatively, you can also get advice by phone or email. We will be happy to help you.

From our Guidebook
Why filter water?
In Germany in particular, there is a widespread belief that our drinking water is of impeccable quality. So why should we buy a drinking water filter? Why are only around 60 pollutants covered by the Drinking Water Ordinance? Find out more here.
Which ingredients can be found in our Tapwater?
We clarify which pollutants and health-relevant substances are in our water. We also explain how the pollutants get into the water in the first place, what effects they have on our health and how harmful substances can be reduced from the water. Find out more here.
How useful are water filters?
Although Tapwater in Germany is strictly monitored, in practice it has serious shortcomings, at least from time to time. This is partly due to the fact that many substance concentrations, such as heavy metal or drug residues, hormones, microplastics and pesticides, are neither listed nor taken into account by the German Drinking Water Ordinance.
For this reason, you should always use filtered water if you want to drink your Tapwater or use it to clean or prepare food. Unfiltered water is also sufficient for rinsing or washing your hands.
