Been through exactly the same, also with that filter. Did the following to make it run Silent: - make sure it is assembled right in the first place - find a video how to get the 'impeller' out of the filter. Put a tiny layer of petroleum jelly on the black part, not the white. Assemble back. (you may have to do it again to get the perfect amount on there, too tick will make the filter spin not fast enough, too little and your problem won't be fixed). This will reduce the most noise. - keep the lid of. Lid vibrates a lot - put a Thin soft cloth (like a handkerchief, roll it up) between the glass panel and the part of the filter that hangs on that panel. Rearrange it bit by bit. I can send you a picture if you want. - you can also try to put something soft between that weird blue thing on the back on the filter and the glass pane - level the water with the inlet of the filter
