After the test weeks in our family and friends, I can only praise the BWT cartridge. In autumn / winter season even up to 5 liters - - We usually 2 liters min. Of tea. The coffee, too, but not in such proportions ;-). I find that the tea just as the coffee tastes much better! The flavor is full, the taste is fine, on the tee there is no more film, the one often has other forms. I drink very much like latte macchiato and the tastes even better recently. Our friends and family have noticed the difference and expressed praise. I could even my mother, who held nothing * far * from the things that convince you that the BWT cartridges improve the water and that they can enjoy their tea as tea drinker even better. Together chamfered:
Cartridges fit easily into Brita Maxtra water filter.
-Filtereigenschaften Were great - descaling of appliances you could leave it out completely.
-taste Of pure water less convincing but tea, coffee, cappuccino and all other drinks taste definitely better.
-Mg2 + Filter technology eliminates the oral magnesium supplements.
