The PUR Classic Faucet Filtration System, White Finish was soo easy to install.  It came with 4 different faucet adapters which is amazing.  The metal faucet adapter fit perfectly with my faucet. After activating the filter, the taste of the water is definitely different it taste much cleaner and crisp.  I was buying up to six cases of bottled water a month I will be saving a little money using this product.  Thank you PUR for such a great product.
