Query: it is good

shipped on time. wonderful tasting clean water. i have major pain issues and i need to drink almost a gallon of water every day and even though it may filter a little slower than some other pitchers, there are no leaks, and i have no question that the water i am drinking now is improving my pain and life in a way i couldn't achieve with tap water nor afford with one of the systems available for hundreds of dollars. Amazon and Pur... great combination! order yours today! you won't regret it!!
