Cleaning noise from a laser scan. Any advice?

Looking to clean up a lot of background noise around objects. Either random isolate vertexes or almost a halo around objects. Is there any kind of routine that might be able to automatically remove these points from the point cloud.

I usually use the "Segment" tool (looks like scissors) and cut/delete those areas out. Zoom around your cloud, tilt to best view of the redundant data, snap a segment line (green) polygon around the data and then pick the "Segment Out".
There's a couple of good YouTube videos showing the usage:

Yeah, thats what i've been doing, its... painful. I've been experimenting with some good luck the SOR and Noise filters, just realized today they were cleaning areas that i wanted to keep. /sigh
