Query: Whirlpool 4396710 KitchenAid PUR - Water Filter, 1-Pack

The shipping was quick but when I opened the red cover I heard the pop sound and there was water or some liquid inside. I read other reviews which states that it is used one if it makes the pop sound, which it did. I am not going to buy another one of this.
