Ctrl-click on the flows pane and start typing filter and the node should appear. If not then you must be using an old version of node-red when it was called rbe, so type that. Then add it to the flow and look at the help text for it.

Check, using a debug node, what the message looks like before the filter node. If the messages are different then the filter will not block them.
