Junk Filter Question

I have designated an email address to receive payment notification
emails from paypal when ever a sale is made on a website...

Unfortunately, the notifications keep getting caught in my Junk
mailbox.  

I have set a filter to transfer any email from 'paypal.com' to a
certain folder, and I have set another filter to transfer any email
with the subject 'Notification of payment received' (which is always
the subject header for this notices), as a back up / failsafe.  

Despite both filters (which have been dragged to the top of my filter
list), these notification emails are still getting directed to my Junk
mailbox.

How can I change my filters to get these emails to be properly directed
where I choose so that  I don't run the risk of missing/losing them in
my Junk folder?

Thanks for any advice with this!
