Easy way to Bulk Delete emails

Easy way to Bulk Delete emails

We get a lot of email into our TeamInboxes and we need to go through now and delete a lot of them. 
Yes, we can use filters but the select all, only allows for 250 threads at a time, once you page down the screen to get that many found.

Is there a way / tool to be able to use those filters to do bulk deletes on existing threads?
