After we've set up a Trigger to begin the flow, we need to determine what "conditions" must be met in order to proceed (if any), before we can run any Actions step. These "conditions" are your Filters.
Field Changed
Check if a specific Podio Item Field has just been changed in value.
This is an important step in Update Flows
Field Value Match
Match a Podio Item Field to a specific value (eg status='new')
Field Previous Value Match
Match a Podio Item Field's previous value to a specific value (eg status was 'new').
Creator / Editor
Check who created this revision in Podio that triggered this flow.

Match a specific date, day of the week or day of the month.

Check the contents of a triggering comment.
