5 out of 5 starsVery fast delivery, unobtrusive packaging and beautiful product design. I've now put the filter into operation - right away I would like to suggest an improvement for the 2.0 version: sanding the outside of the sleeve so that there is more grip on the paper. The filter can be turned easily, but it slips a little in the paper if you turn it loosely. Otherwise, it's a great idea, super sustainable and does what it's supposed to do. I will recommend this part to my colleagues. With that in mind, see you at the next party in Bonn & kind regards, Patrick R.

5 out of 5 starsI have used Actitube activated carbon filters for almost twenty years and the expense of purchasing them is not exactly convenient but with this kit I have solved everything: high quality of the carbons and the surgical steel filter is very well made in all its aspects. I highly recommend the purchase to those like me who use this type of filter!

5 out of 5 starsThe filter is great and works perfectly. Unfortunately, the cleaning bottles are not leak-proof. The cleaning agent ran out completely overnight. Maybe something needs to be improved.

Vielen Dank für das Feedback. Das mit den Reinigungsgefäßen nehme ich für die Version 2.0 mit auf :)
