The filter cartridges hold a little longer one probably on average. a week in a massive daily use as the filter cartridges of DM & Co. What I do not found so great was that I got sent a package which is packaged in original box and the other consisted of 3 non-individually wrapped cartridges. Moreover, I came out of a cartridge then also a little more water towards the open as it vapor actually should have been. Well it was just water. On average, the cartridges do what they should and that filter water longer as no-name products.
