because after many months of operation, it gums up and doesn't spring open as it should when you're done dispensing filtered water. You have to switch between filtered or not manually. Since it can't be disassembled for cleaning, I bought a new one to regain its automatic function. But, well worth the investment for a device that filters just the water you're going to drink. This is tops for a faucet system. Wash your hands under unfiltered water, then pull the button to fill a glass of filtered to drink. Cartridges are readily available and easy to change. It comes with adapters to fit most faucet threads and is very easy to install.

It was easy to install. Easy to use. The water has no chlorine taste anymore. We save a lots of money to drink the water from home, not from the store. Our water became drinkable, enjoyable taste .
