Query: Good Filter

I first tried Brita faucet mount filter, that did not work well at all. The water tasted nasty and there were also leakage.I read reviews on this Culligan water filter and decided to give it a try, it actually works much better than the Brita filter I tried. The water tasted pretty clean and fresh, there is no leakage, very easy to install. The Culligan water filter is simple and convenient. I've used it for a month now and it is still great! However, the knob that changes from regular water to filtered water gets stuck from time to time. Overall, good filter!
