Sometimes well water is not the best tasting, this makes a good filter essential. I have used some filters that make the water drinkable, the PUR 7 cup basic pitcher actually made the water taste good. I don't remember how many contaminants it said it cleaned, I just know it made my normally "funny" smelling water taste and smell like bottled water. It also filters faster than my old one. It feels like a good quality product, right down to the ergonomic handle with a rubberized grip. The PUR 7 cup Pitcher worked so good I went out and bought one for my Mom. I love this thing!
