Use the destination filter tester during setup to verify that you're filtering out the right events. Filtered events show up on the schema page but aren't counted in event deliverability graphs.

Destination Filters can't target properties or traits with spaces in the field name. As an alternative, use[Insert Functions](/docs/connections/functions/insert-functions/), which let you write code to take care of such filtering.

The check for unsupported events types happens before any destination filter checks. As a result, Destination Filters can't prevent unsupported event type errors. To filter these events, use the[Integrations Object](/docs/guides/filtering-data/#filtering-with-the-integrations-object).
