Good afternoon gurus

I have recently bought a chromebook for the purpose of couch surfing, email previewing etc.  I have a personal POP3 account with Paradise.net.nz and a throw-away account with GMail.  I have linked my POP3 account to GMail so now ALL my emails turn up in GMail.  I can set up a filter to send designated senders to a folder but what I want to do is send all my POP3 mail to a folder to separate personal from junk.  I have looked at the Chromebook Forum but can't find the answer there.

My question then is can I redirect all POP3 mail to a folder in GMail?
