    had one a few months now, filter media is still good...it has definetely reduced the water marks on those occasions where I have left the car to dry naturally and not towelled off (which isn’t often to be honest, can’t stop the habit of using the microfibre towel!) but , certainly on obsidian black, you will still see water marks unfortunately....

    What you may actually be seeing is dust that has settled in a windy day in the beads of water on your immaculately waxed car.

    If the resin media is still good and producing 0ppm water, there will be no water spotting until the media passes its sell by date
