I have been using this for a few weeks now and love the pureness of the water. This pitcher filters water quickly. The only downfall of it is that it is not big enough for this water drinking fool. I am able to get three large glasses of water out of each pitcher, so I am refilling this pitcher a lot. When you first get it you will need to fill the pitcher and throw out the water. It seems to have charcoal in the water. It only happened on the first fill which it is stated in the instructions that it might happen. I can see the difference of the water between this and tap water. The tap water has a cloudy hue to it where the filtered water is crystal clear. I never thought water had a taste but you can taste a difference between the filtered and tap water. Overall I am very happy with this pitcher and will be using it for the foreseeable future.
