I love my Pur Classic Faucet Filtration System! It was so easy to install and it works well. My water tastes so good and I feel safe just drinking water from the tap now. I love the convenience of having it attached to the faucet. I have used water filters in a container to keep in the fridge for my drinking water. The faucet filter makes it more convenient to use for running water for cooking and giving to my pets.
