Steve,
You can set the width of the K2 filters to whatever you desire. There
are 4 filter widths for each mode (CW, RTTY, and SSB). The practical
most narrow CW bandwidth is 200 Hz. Usually, at settings more narrow
than that, the signal is attenuated rather than narrowed.
For additional information on setting the K2 filters, take a look at my
webpage www.w3fpr.com Step 3 of the K2 Dial Calibration article.

Is it possible to get a narrower filter than 400?
