How to filter out duplicate items before creating new airtable records?

Describe the problem/error/question

I am trying to filter out content that has been retrieved from an RSS feed, format it, and send it to my airtable database. However, this RSS feed isn’t updated with new content very frequently, so when I run my workflow it causes duplicate records to be created in the airtable. I’ve checked other sources for an answer but nothing seems to be working. I’ve left off at the airtable node because I’m not sure how to use the filter by formula option, as I can’t seem to find good documentation on it and this is my first time using airtable. Can someone please help me start from where I left off?

Much appreciated

What is the error message (if any)?

None
