Filter seems to work as well as anything else. My air is pretty clean and my water is a little better than average so there's not a lot of stress on the filter. I just don't like this type of filter setup. I like the Lasko 1128 humidifier. The filters are cheaper and the thing is a humidifying beast. It is about as loud as a jet plane however
