It says what it promises. The case is very high quality and the filter. It reduces salts as it says because the water in the Evros is terrible with salts, odors, and taste, but the filter eliminates them all provided you have a filter for sediments. In the main supply, at least that's how I have it. It helps your coffee to have its own taste and not from the water. With a couple of glasses, you quench your thirst, so it has the necessary elements for water. The replacement ultracarb si, if you shake it, you will hear small stones inside, but it is not broken, that's how the blue or the resin does for salts. Finally, the only negative thing I saw is that you have to let the water run through the filter for 2-3 seconds and then put the glass because otherwise, if you put it directly, it will leave a metallic taste in your palate, while if you let it run a little, it won't leave it like that at least that's how I feel

Your filter provides water equivalent to bottled water, it is the first replacement filter, I have had it for about 4 months and the water is crystal clear!!!
Very easy connection, with relatively good and fast flow. The filter lasts from 8 to 12 months and needs cleaning every 2-3 months with a sponge, it shows less salts than the original doulton filter, so it is slightly better than the pre-installed one in the mechanism.

Top filter. Incredible water quality and very good taste without odors. I think there is no better one

I notice a difference in the taste of the water. You just have to let it run for at least 20 minutes on the first day and then it is suitable for use.
