We use one of the cylinder filters that replaces a short section of removable tubing under a counter. It is primarily there to filter incoming city water, so that our dish washing, showers, and sink water is clean. It gets changed once a year. For drinking and cooking, we never trust the city water - we bring a few jugs of our home filtered well water along for that.
