We have this water filter already bought a 2nd time (the first was for us, the 2nd is a gift). The filters are a little pricey (but that they are at other brands as well), but the coffee tastes better and the machine must be decalcified much rarer. However Pur I'd rather drink our hard tap water, filtered water tastes I find bland and stale. Since I do not use more shampoo, the water filter more often in use, because I again sink through my hair after washing with the filtered water, which helps a lot.
