I am skeptical by nature, therefore was my expectations compared to the Brita Maxtra Water Filter ... and was quite surprised.
The calcification decreased close to zero. Of course I checked with a test strip and then had it officially. I've been using the system for two years now and had since not descale, simple cleaning is enough my equipment.
The use of the Brita Maxtra is very simple: Just let tap water run through the machine, wait for few minutes, and it's ready to use.
That was the objective part, subjectively I want the water now described as soft, taste a little sweeter and more pleasant.
Granted, the refill cartridges are not cheap pleasure in the long run. But for me it's a piece of practical quality of life. And I as a frugal accountant found out for myself that you can use the given four weeks not only cartridge, the filter effect is sufficient even good five to six weeks. Beyond this date, I have already discovered then however slight white marks.
I am completely satisfied, Brita Maxtra delivers an excellent result.
