Whisper quiet, I could barely even tell it was on. I literally had to put it on high and put my ear to the pump to hear it. What a difference from the old days. I just hope it stays this quiet.
I got mine last night and I was blown away how much quieter they are. I put mine on about 75% and they are so quiet I don't notice them. Even at 100% they are quiet. Unfortunately it makes me much more aware how loud my return and overflow are! One of my MP10's is over 5 years old (but wet side was replaced last year), and it's basically brand new pump.
