A reasonable AM filter is not good for SSB or CW.

Once you start getting into better filters, they start to be much more mode specific, so you wind up using mode specific ones, switched for the modes you want to be able to use.
Don't be put off a filter by any reports that it's not good for modes it wasn't designed for. The modes are sufficiently different in their needs that this is actually a good sign!
