Somehow, the price difference must indeed be justified

Fast and uncomplicated delivery. However, not much to expect from the product. The filter is not more than half as thick as the original - thus it also contains significantly less activated carbon.

Furthermore, you have to handle the filters carefully, otherwise crumbles plenty of coal out. As someone remarked before, the lattice spacings are still quite large.

One of the two filter fits perfectly on the connection. The second does not fit properly and will depend somewhat loose it - even if I attach the filter to the other terminal. On both sides of the same problem.

All in all, the product okay, what do you expect for the money. Next time I will, however, draw back to the more expensive original filters. Thinking to get a whole but cheaper - partly because of the significantly higher filter performance.
