Product review (5 stars): Slightly louder, but not too much so
Picked up one of these when we needed to replace the filter in our Samsung refrigerator. The water now comes out at a slightly higher pressure and the filter is a little bit louder, but not so much that it bothers us, just enough that we noticed at first.

I had read other reviews that said there was some minor leaking caused with this filter, but we didn't have these issues, at least yet.
