The Longlife Mg2 + cartridges from BWT is filter cartridges for water filter systems that do exactly what filter cartridges for water filter systems do so: you liberate the tap water of calcifying and flavor-impairing metals. And they do reliably. The filtered water is absolutely clear. Only the bottom of the filter jug sit down sometimes some coal particles that are there, however, only be seen with a lot of concentration. This happens at Brita cartridges however well. Handling is both immediate - with the subjective impression that the filters would go faster with BWT, relativized by a measurement with stopwatch has. Both do not take much. But you can still say that the cartridge of BWT actually a little better in the jug Brita Maxtra fits as the cartridges. Continues to be positive, that before the first use only once has let through water that is to be discarded. The Brita cartridges you have to do that twice.
The taste is of the filtered water be faulted. It tastes soft and fresh, and my opinion is pure tap water be diluted purely as preferable even when the tea definitely - the latter not least because it protects the device. Since I use water filter, has still not deposited lime in my kettle, and that has not changed even after the change from Brita at BWT.
Positive highlight the higher filter performance is according to the manufacturer, the here is 120 liters (with just Brita 100 liters). Both will however indicated that they have to change after 4 weeks. I think that's a bit exaggerated and therefore consider myself also prefer to the liter indication.
As for magnesium, which is here allegedly added to the water, I can not comment. I have not a test lab at home. Can be tasted to the under any circumstances, and also the direct comparison with Brita-filtered water brings with much imagination produced a difference. Ultimately, that's really just a matter of good sense to do something for his health. Negative impact on this course, I have not noticed particularly positive but neither (but I'm not someone who wakes up at night with cramps in the calves or the like).
Conclusion: These cartridges are ordinary, but actually compared with other manufacturers normal cartridges for water filter that will fit into any newer filter jugs, which can accommodate oval cartouches. The handling is easy, relatively little water-Schwechat Sartorius membranes, and the taste, of course, as opposed to tap water is hard significantly better. The added magnesium is probably useful for people who must otherwise rely on magnesium tablets.
Since the cartridges are, instead, but actually good overall, but not in any way outstanding better than the other manufacturers a little more expensive, there is of me in accordance with a "Like" 4 stars.
