Simply re-define the nwfilter in question using virsh nwfilter-define.
Any VMs using that filter will automatically update.

Thank you for the quick reply.
As for adding the nwfilter to a guest that does not already have the
filter, will that guest need to be rebooted? Or can I add it to the
guest via 'virsh edit'?
I ask becase, from what I can tell, adding a new filter via 'virsh edit'
doesn't seem to work -- though it's good to know that once a 'filterref'
has been defined in the guest, it can be adjusted on the fly.
