As someone who is concerned with quality of water, I've been drinking filtered Brita water for years, so I bought a space saving water jug with this filter in it because we bought a new fridge, but was very surprised at how weak this filter was. I am very surprised that it only lasts 4 weeks (which is a ridiculously short filter life) and it's contents are very loose inside to where you could see through it. This filter lasted almost the the whole 4 weeks. by the end, I tasted the tap water even after pouring it through several times. There is a rough patch at the bottom of the pitcher where the limescale has been getting through (in the spot where it trickles inside, and, no, our water here isn't that hard.) It is not just the one filter but a few I have used and everytime it's the same. I went back to bottled water again because I feel that I don't even want to drink the water out of my pitcher. Now I use it to water plants. I miss my old Brita filters where they were packed tightly and consistently and gave me CLEAN, crisp, great-tasting water. Whoever designed these should be fired.
